PURPOSE: To refine a heavy slurry oil fraction at good efficiency by dispersing catalyst fines in a feed oil, passing the mixture through a hydrovisbreaker to lower the viscosity, separating the effluent into higher and lower boiling fractions and passing the respective fractions into a cracking unit so as to convert them into lower-molecular-weight oil products.
CONSTITUTION: In a process for converting an oil containing heavy hydrocarbons, a feed stock containing cracking catalyst fines is passed through a hydrovisbreaker 24 to lower the viscosity of the feed oil, the hydrovisbreaker effluent is separated into at least one low-boiling fraction and a high-boiling fraction in a separator 30 to incorporate the high-boiling fraction in the dispersed cracking catalyst fines. Next, the at least one low-boiling fraction is discharged as a product stream from the separator 30 and passed to a cracking unit 36 to convert it into lower molecular weight hydrocarbon product oil, and the higher boiling fraction containing the dispersed cracking catalyst fines is passed into a catalytic cracking unit 44 to convert the higher boiling fraction into lower molecular weight hydrocarbon products. Thus, a heavy slurry oil fraction is refined by cracking.

PURPOSE: To provide a process for preparing low-sulfur and high-sulfur cokes which can efficiently obtain low-sulfur and low-sulfur cokes respectively from a heavy fraction and a light fraction by catalytically hydrogenating an untreated heavy fuel oil to lower the sulfur content, separating the product into a heavy fraction and a light fraction, subjecting each fraction to delay coking, and then conducting baking.
CONSTITUTION: In preparing a low-sulfur coke and a high-sulfur coke from a single starting material, an untreated heavy fuel oil 2, such as a still residue oil, is catalytically hydrogenated with hydrogen 6 in a hydrogenator 4 to lower the sulfur content of the product to not more than 0.75 wt.%, the hydrogenation product is separated by means of a fractionator 10 into a heavy fraction 42 and a light fraction 14, the light fraction and the heavy fraction are subjected to delay coking respectively in coke ovens 16, 44, and the resultant crude coke products are baked respectively in baking machines 24, 52. Thus, a low-sulfur baked coke 26 is obtd. from a coked light fraction, while a high-sulfur baked coke 54 is obtd. from a coked heavy fraction.

Disclosed is a catalytic cracking process which includes more than one catalytic cracking reaction step. The process integrates a hydroprocessing step between the catalytic cracking reaction steps in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, the hydroprocessing step is included between the reaction stages, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step. |

For upgrading heavy slurry oil containing catalyst fines from a catalytic cracking operation, the viscosity of the slurry oil is lowered in a hydrovisbreaking process step. In a preferred embodiment an admixture of the fines containing slurry oil and a metal containing resid oil fraction, resulting from a crude distillation, is passed through the hydrovisbreaker. The hydrovisbreaker effluent is separated into higher and lower boiling fractions with the lower boiling fraction preferably passed through a cracking unit so as to covert the lower boiling fraction to lower molecular weight hydrocarbon products. |

A synthetic fuel gas is produced from crude oil by a combination of inter-related steps which separate the oil into several fractions, a first ethane and lighter gaseous fraction, a further gas fraction containing propane and butane, a gasoline containing fraction boiling up to, about 400* F, and a heavy oil or residual fraction, the first two fractions are treated with caustic to remove sulfur and sulfur compounds therefrom, the third fraction is hydrodesulfurized and the fourth fraction is catalytically cracked to extinction to produce gaseous products and an additional gasoline fraction which is hydrodesulfurized whereupon all except the first fraction are combined and then converted by known operation to produce a synthetic natural gas or fuel. This gas or fuel can be combined with the first gas fraction either before or after hydrogen has been removed from it.

The combination processing concept described involves using a low severity reforming operation primarily as a source of hydrogen for CHD processing and other treating operations in the production of low octane reformate (90-95 R+O) which is then upgraded by cracking over a crystalline aluminosilicate catalyst to produce a higher octane gasoline boiling product. Alkylation of reformer and FCC light ends contributes to gasoline boiling product yields.
