| 141 | Process for deep desulfurization of cracked gasoline with minimum octane loss | US13988316 | 2011-11-16 | US09260672B2 | 2016-02-16 | Sarvesh Kumar; Alok Sharma; Brijesh Kumar; Anju Chopra; Santanam Rajagopal; Kumar Ravinder Malhotra |
| The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70° C.), Intermediate Cut (70-90° C.) and Heavy Cut (90-210° C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurized by caustic treatment using CFC along with Light cut or separately desulfurized before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process. | ||||||
| 142 | Process for the production of low sulfur, low olefin gasoline | US10974666 | 2004-10-27 | US20060086645A1 | 2006-04-27 | Kerry Rock; Yi-Gang Xiong; Arvids Judzis |
| A process for the production of low sulfur, low olefin gasoline wherein a cracked naphtha, such as a full boiling range cracked naphtha, is first separated by fractional distillation into at least two fractions while simultaneously selectively hydrogenating the polyunsaturated compounds contained therein. The mono olefins in the light fraction are then subjected to etherification with alcohol to produce ethers or hydration with water to produce alcohols. The heavy fraction is subjected to sulfur removal by hydrodesulfurization or chemisorption. The two fractions are then combined to produce a low sulfur, low olefin gasoline. | ||||||

| A process for catalytically desulfurizing cracked fractions in the gasoline boiling range to acceptable sulfur levels uses an initial hydrotreating step to desulfurize the feed with some reduction in octane number, after which the desulfurized material is treated with a self-bound or binder-free zeolite to restore lost octane. The process may be utilized to desulfurize catalytically and thermally cracked naphthas such as FCC naphtha as well as pyrolysis gasoline and coker naphthas, while maintaining octane so as to reduce the requirement for reformate and alkylate in the gasoline blend. The self-bound catalyst offers advantages in activity and permits the process to be carried out at lower temperatures. | ||||||

| Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst under endothermic conditions in a second reaction zone. Heat is added to the endothermic reaction zone to initiate and maintain octane restoring reactions. The preferred acidic catalyst is an intermediate pore size zeolite such as ZSM-5. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The addition of heat at the second zone prolongs hydrodesulfurization catalyst life by allowing a lower hydrodesulfurization reactor temperature. The addition of heat also maximizes octane increase in the second zone. | ||||||

| Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst system comprising an intermediate pore size zeolite having crystallites of an effective radius of at least 0.25 micron. The treatment over the large crystal acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenation treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha, with the large crystal size improving gasoline yield by reducing conversion of branched paraffins. | ||||||

| Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5. The treatment over the acidic catalyst in the second step, which is carried out in a hydrogen atmosphere which is essentially free of hydrogen sulfide and ammonia, restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. The hydrogen supplied to the second step may be make-up hydrogen with recycle hydrogen routed to the hydrodesulfurization step after removal of ammonia and hydrogen sulfide in a scrubber. | ||||||

| Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization and treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 in an octane restoration step, followed by separation of a C.sub.9 -containing fraction, and recycling the C.sub.9 -containing fraction to the octane restoration step. A hydrocarbon fraction comprising C.sub.1 to C.sub.3 hydrocarbons may also be separated from the octane restored product and recycled for purposes of alkylating aromatic hydrocarbons and for this purpose, it may be advantageous to introduce a benzene-rich feed, such as a reformate, to the process. The treatment over the acidic catalyst in the octane restoration step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. | ||||||

| Low sulfur gasoline is produced from a catalytically cracked, sulfur-containing naphtha by fractionating the naphtha feed into a low boiling fraction in which the majority of the sulfur is present in the form of mercaptans and a high-boiling fraction in which the sulfur is predominantly in non-mercaptan form such as thiophenes. The low boiling fraction is desulfurized by a non-hydrogenatile mercaptan extraction process which retains the olefins present in this fraction. The second fraction is desulfurized by hydrodesulfurization, which results in some saturation of olefins and loss of octane. The octane loss is restored by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5, to form a low sulfur gasoline product with an octane number comparable to that of the feed naphtha but which contains some recombined sulfur in the form or mercaptans which are removed in a final hydrotreatment. | ||||||

| A sulfur-containing naphtha is separated into at least three fractions. Each fraction is desulfurized separately by a different desulfurization method. Subsequently, the desulfurized fractions are recombined. The intermediate boiling point naphtha fraction is desulfurized by an alkali metal desulfurization process, preferably in the presence of added hydrogen. | ||||||

| A range of lubricating oils is produced by splitting a petroleum fraction boiling above 350*C into light and heavy fractions, preferably at a cut point of 400*-500*C treating the light fraction or fractions by catalytic dewaxing and solvent extraction and treating the heavy fraction or fractions by catalytic hydrogenation and solvent dewaxing. Part of the heavy fraction may be solvent extracted and solvent dewaxed, and part solvent dewaxed only. The catalytic dewaxing process uses a mordenite catalyst and the catalytic hydrogenation may produce either high or super-high oils.

Turbine fuel provided is suitable for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, nonconventional crudes, and other highly contaminated liquids such as refinery residual oils and high sulfur fuel oil. Each fuel is produced as a single product of unit operations, not an ex-plant blend of various refinery products yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbine systems of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise use contaminated heavy crude or refinery residual oils.

| Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula Cu x Zn 1-x Al 2 O 4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SO x and low sulfur hydrocarbons. The by-product SO x is subsequently removed, producing a stream containing a reduced level of organosulfur compounds. | ||||||

| Systems and methods are provided for producing naphtha boiling range fractions having a reduced or minimized amount of sulfur and an increased and/or desirable octane rating and suitable for incorporation into a naphtha fuel product. A naphtha boiling range feed can be separated to form a lower boiling portion and a higher boiling portion. The lower boiling portion, containing a substantial amount of olefins, can be exposed to an acidic catalyst without the need for providing added hydrogen in the reaction environment. Additionally, during the exposure of the lower boiling portion to the acidic catalyst, a stream of light olefins (such as C2-C4 olefins) can be introduced into the reaction environment. Adding such light olefins can enhance the C5+ yield and/or improve the removal of sulfur from thiophene and methyl-thiophene compounds in the naphtha feed. | ||||||
