A process for preparing an activated isomerization or alkylation catalyst composition in which a catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminum compound on an alumina carrier containing up to 20 wt. % of other components involves activating the catalyst by contacting the catalyst with a hydrogen-containing gas at a temperature in excess of 500.degree. C., with the proviso that at least when the hydrocarbon-substituted aluminum compound present in the catalyst composition is not a hydrocarbon-substituted aluminum halide, the catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step. The catalyst obtainable by this process and the use thereof in hydrocarbon conversion processes, such as isomerization and alkylation processes, are also part of the invention. The effect of the high-temperature activation step is that the activity of the catalyst is improved in comparison with a catalyst of the same composition which has not been subjected to the high temperature activation step.

Process for preparing a catalyst suitable for use in isomerizing

A process for the catalytic hydrodesulfurization of hydrocarbon- containing feeds using a catalyst of a phosphorus component, a cobalt component and a Group VIB metal component on an alumina carrier.

Process for the hydrodesulfurization of light hydrocarbon feeds

Disclosed are the preparation of a sulfided catalyst and the use of said catalyst in the hydrotreatment of hydrocarbon feeds. The sulfidation is carried out by ex situ presulfiding of a fresh or regenerated catalyst, followed by the resulting material being contacted in situ at elevated temperature with hydrogen gas in combination with either a sulfiding agent, e.g., hydrogen sulfide, or a spiked feed.

Process for the preparation of a sulfided catalyst

Disclosed is a process for the ex situ presulfidation of hydrotreating catalysts employing organic sulfur compounds with a boiling point exceeding 100.degree. C. and satisfying the formula

Process for the preparation of a presulfided and sulfided catalyst

This invention concerns a process for the preparation of a gasoline boiling hydrocarbon from a mixture of hydrocarbons specifically defined. The hydrocarbon feedstock is a mixture of two hydrocarbon oils with the first hydrocarbon oil having a Conradson carbon test value C.sub.1 and % w such that the quotient of C.sub.1 /R is higher than 0.8 and a second hydrocarbon oil having a Conradson carbon test number C.sub.2 such that the quotient C.sub.2 /R is lower than 0.2 wherein R is equal to the reactor carbon requirement for the particular catalytic cracking unit and is between 3 and 8 percent by weight.

Catalytic cracking of hydrocarbon oils from two mixtures boiling above

A process is disclosed for the preparation of a more active paraffin hydrocarbon hydroisomerization catalyst from synthetic mica montmorillonite, preferably a nickel synthetic mica montmorillonite catalyst, which may also contain palladium, by treating the catalyst with one or more compounds comprising chlorine which can further release one or more protons and/or hydrogen chloride, and preferably by treating with hydrochloric acid.

Process for the hydroisomerization of paraffins

A process for hydroisomerization of C.sub.4 -C.sub.7 paraffins with a nickel and/or cobalt synthetic mica-montmorillonite catalyst which has been pretreated with hydrogen at a temperature of at least 400.degree. C.
