Abstract: There is provided a method for improving the attrition resistance and heat stability of a silica-alumina fluid catalytic cracking catalyst where the catalyst contains up to 35 weight percent alumina by treating the catalyst with steam such that the catalysts stability factor is increased to a value of at least 12.5. The above treatment provides an improved fluid catalytic cracking catalyst for utilization for the cracking of a hydrocarbon charge under the catalytic cracking conditions.

Abstract: The viscosity index of a hydrocracked lubricating oil stock boiling in the range of about 600*-1100* F. is increased by fractionating the stock into a light fraction boiling from 600* F. to about 750* F. and a bottoms fraction; mildly hydrogenating the light fraction and subsequently reblending the hydrogenated light fraction with the unhydrogenated fraction. Low boiling cracked hydrocarbons may be removed from the reblended lubricating oil to adjust the initial boiling point temperature to a desired value.
Abstract translation: 通过将原料分馏成沸腾至600°F至约750°F的轻馏分和塔底馏分，将沸点在约600°-1100°F范围内的加氢裂化润滑油原料的粘度指数提高。 轻轻地使轻馏分氢化，随后用未氢化的馏分使氢化轻馏分反应。 低沸点裂化烃可以从再润滑的润滑油中除去，以将初始沸点温度调节至所需值。

Abstract: Hydrodesulfurization of an atmospheric residuum is effected by separating it into a vacuum gas oil and vacuum residuum and desulfurizing the gas oil fraction under less severe conditions than the heavy fraction. The vacuum residuum is contacted initially with a catalyst containing a Group VI metal and Group VIII metal or their sulfides on an alumina support containing 2-4 weight percent silica, a surface area of at least 250 m2/g. and a pore volume of at least 0.6 cc./g.; the effluent from the first zone is mixed with the gas oil fraction and the resulting mixture is then contacted with the catalyst at a lower temperature than the effluent temperature from said first zone.

Abstract: Petroleum oils of reduced sulfur content are produced by introducing into a catalytic hydrodesulfurization zone a residuecontaining petroleum oil of which at least 10 volume per cent boils below 1,000*F. separating the hydrodesulfurization zone effluent into a fraction boiling below about 1,000*F. and a fraction boiling above about 1,000*F. desulfurizing the fraction boiling below about 1,000*F. and combining the product with the fraction boiling above about 1,000*F. The catalyst in the first hydrodesulfurization should have a surface area of at least 250 m2/g., a pore volume of at least 0.6 cc/g and should contain at least 2 percent by weight silica.

Abstract: There is provided a method for increasing the catalytic cracking activity, selectivity and attrition resistance of a crystalline aluminosilicate containing catalytic cracking catalyst by treating the catalyst at a temperature above about 1300*F. and below the thermal destructive temperature of the crystalline aluminosilicate in the absence of steam. The above treatment provides an improved catalytic cracking catalyst for utilization in the cracking of a hydrocarbon charge under catalytic cracking conditions.
