摘要： A metallic reforming catalyst, consisting of platinum and iridium or platinum, iridium and copper on a porous carrier provides excellent conversion of naphtha to C.sub.5.sup.+ product. A method of incorporating the metals or metal compounds on the carrier and preparing the finished catalyst using dimethyl sulfoxide is a novel procedure and provides unexpected catalytic properties. Novel reforming operations using these catalysts under moderate or severe conditions do not drastically alter the product yield.

摘要： Nitrogenous compounds especially bases such as ammonia vapor are used to control the operation of a hydrocracker or catalytic dewaxer. Catalyst activity and selectivity may be controlled by addition of the base to the feed, for example, to control the balance between isomerization and hydrocracking in an operation using a zeolite beta catalyst. Runaway conditions may be controlled by the addition of nitrogenous compounds to regulate the temperature profile within the reactor.

摘要： An FCC or fluidized catalytic cracking process and apparatus for converting heavy metals laden crudes is disclosed. The heavy feed, conventional catalyst and an additive or vanadium getter contact the feed in a riser reactor. The additive is segregated from conventional FCC catalyst upstream of the conventional FCC regenerator. An elutriating, upflow riser reactor may be used with a coarse, rapidly settling getter. A fine, slowly settling getter may be used, with getter segregation achieved by using an elutriating cyclone on the riser outlet, an elutriating catalyst stripper, a sieve, or the like. The spent getter may be used once through, regenerated in a separate getter regenerator, or used as a source of fuel. Alumina and sponge coke are preferred getters.

摘要： A method for improving the cetane number of an aromatic hydrocarbon oil such as FCC light cycle oil and thereby increase its value as a blending stock for diesel fuel or heating oil. In one embodiment, the FCC light cycle oil is alkylated in the presence of a solid acidic catalyst and with a linear mono-olefin having a chain length of at least five carbon atoms. In another embodiment, the light cycle oil is alkylated with an olefin having three to nine carbon atoms or a mixture thereof and with ZSM-20 as catalyst to decrease the frequency of catalyst regeneration.
