专利汇可以提供Steam-reforming catalyst专利检索,专利查询,专利分析的服务。并且PURPOSE:To make it possible to carry out the steam-reforming of gasoline containing aromatic olefin in good efficiency, by using a catalyst prepared by supporting nickel and vanadium oxide by a diatom earth carrier. CONSTITUTION:On the basis of a supporting amount to a diatom earth carrier, 30-50wt% nickel and 3-30wt% vanadium oxide are supported by said carrier and the sum amount of both of them is adjusted to 40-70wt%. In using this catalyst in the steam reforming of hydrocarbon such as gasoline, precipitation of carbon to the surface of the catalyst is eliminated and high catalytic activity is shown in steam reforming. In addition, a condition carrying out steam reforming by using this catalyst is not limited specially but the amount of steam to hydrocarbon is 10-50mol/mol, a temp. is 300-500 deg.C, reaction pressure is 0- 10kg/cm and liquid hr. space velocity (LHSV) is pref. 0.1-3/hr. Further, the amount of aromatics in gasoline is pref. 10-40vol% and the amount of olefin therein is pref. 10-30vol%.,下面是Steam-reforming catalyst专利的具体信息内容。
