    摘要: A hydrocarbon fraction, preferably in the kerosene boiling range containing a substantial proportion of C.sub.9 + hydrocarbons is contacted with an n-paraffin fraction, such as n-pentane, over a catalyst of acidic functionality, such as Pd/zeolite beta, under conditions of hydrocracking sufficient to convert the feed to lower boiling range materials of high octane number. The n-paraffin cofeed promotes isomerization and suppresses production of n-paraffins.

    摘要: A process is disclosed for operating a refinery gas plant such as the unsaturated gas plant of a catalytic hydrocarbon conversion process that results in a reduction of the corrosive effect of acid gases on the gas plant vessels and equipment. The process comprises contacting acidic hydrocarbon feedstreams to an unsaturated gas plant separator zone with lean acid gas absorbing absorbent in an absorbtion zone comprising at least one liquid absorber bed and one vapor absorber bed. The liquid and vapor absorber beds are located upstream of the separator zone. The feedstreams to the gas plant comprise unstabilized, or wild, liquid gasoline and liquid and vapor output streams from the liquid-vapor separator for inter-stage wet gas compressor of the conversion process main fractionator. Accordingly, these feedstreams are deacidified before separation in the USGP deethanizer-absorber, sponge absorber, and debutanizer. This also eliminates the need for deacidification of the gas plant product stream.

    摘要: Light aliphatic streams containing C.sub.4 - olefins are upgraded to C.sub.5 + gasoline in a two-stage process. In the first stage, olefins are oligomerized to C.sub.5 + olefinic gasoline. Unreacted light aliphatics including ethylene as well as light oligomerization byproducts are then charged to a second stage aromatization zone. Catalysts useful for both stages include medium pore zeolites.

    摘要: Valuable product yield and catalyst useful life are improved by regenerating spent catalyst at temperatures below those maintained in the reaction zone. Relatively cold regenerated catalyst is then preheated and reactor effluent product is quenched by directly contacting the regenerated catalyst with hot reactor effluent product. The quenching step minimizes undesirable thermal cracking of valuable product to C.sub.2 -light gas. The process and apparatus are useful both in aromatization and dehydrogenation of aliphatic hydrocarbons.
