Increased yields of middle distillate and jet fuel and increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a beta zeolite and a Y zeolite having a unit cell size from 24.37 to 24.43 angstrom. The catalyst has a relatively high amount of Y zeolite relative to beta zeolite.

Increased yields of LPG and middle distillate products are obtained in a two stage hydrocracking process by the use of a catalyst containing a beta zeolite. In embodiments, the beta zeolite has not been hydrothermally treated or has been hydrothermally treated at a relatively low temperature. In another embodiment, the catalyst contains a relatively low amount of beta zeolite.

An improved process for the vapor phase fluorination, especially fluorination of 1,1,1-trifluoro-2-chloroethane (CFC-133a) with HF to produce 1,1,1,2-tetrafluoroethane (HFC-134a) employs a catalyst which preferably consists essentially of boehmite and Cr(OH)Cl.sub.2.2H.sub.2 O, combined and extruded to form particulates and then heated in nitrogen.

Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by raising the density of the polymer precursor of the carbon molecular sieve through adjustment of the conditions for suspension polymerization of vinylidene chloride.

Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by impregnating a polymer precursor of the carbon molecular sieve with additional monomers and polymerizing the monomers before carbonizing the precursor.

The instant invention provides an olefin polymerization catalyst comprising chromium and titanium supported on silica. The catalyst is prepared with a low sodium ammonia-stabilized silica sol which has an average silicate particle size of from about 2 to about 6 nm. The catalyst produces polyethylene or a copolymer of ethylene and another olefin selected from the group consisting of the C.sub.3 to C.sub.8 mono 1-olefins, the polymer having a high melt index and a narrow molecular weight distribution.

A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock in an initial catalyst zone with a catalyst comprising platinum, germanium and halogen on a solid catalyst support. The product from the first catalyst zone is contacted in a terminal catalyst zone with a catalyst having the essential absence of germanium and comprising platinum, halogen and a metal promoter on a solid catalyst support.

The product from the first catalyst zone is contacted in a second catalyst zone with a catalyst comprising platinum, germanium, halogen and a metal promoter on a solid catalyst support.

A process for converting aliphatic hydrocarbons to aromatic hydrocarbons is disclosed. The process utilizes a nonacidic hydrocarbon conversion catalyst comprising potassium form L-zeolite, a Group VIII metal, and an alumina-magnesia binder wherein the weight ratio of zeolite to binder is at least 1:1.

Catalytic process for the conversion of hydrocarbons

A novel catalytic composite for the conversion of hydrocarbons is disclosed. The catalytic composite comprises a refractory inorganic oxide, a first uniform dispersion of a platinum component and a rhenium component, and a second dispersion of an indium component thereover. The composite further comprises a halogen component and a sulfur component. In addition to a novel catalytic composite there is also disclosed a method of preparing the composite and a novel process for the use of the composite.
