In a process for preparing a dehydrogenation catalyst of the type in which a support comprising zinc aluminate is impregnated with at least one of platinum and tin from an impregnation solution, the improvement comprises simultaneously impregnating the support with the platinum and the tin by contacting the support with an impregnation solution which comprises, in solution, a tin compound, a platinum compound, and carboxylic acid. The thus prepared catalyst can be employed in the dehydrogenation of at least one alkane containing 2-8 carbon atoms per molecule in the presence of steam.

A novel polymerization catalyst system comprising a diluent, a substrate, a nickel compound wherein the nickel is in a zero oxidation state and picolinic acid and a method for making such catalyst system is described. The polymerization catalyst system can be used in a process for the polymerization of polymerizable olefins.

Olefin polymerization

A process for converting catalytic cracking catalyst fines to a shaped composition comprises acid-treatment of catalytic cracking catalyst fines, followed by separation and drying of the acid-treated fines; preparing a shapable mixture by mixing the dried catalyst fines with calcium aluminate, sodium silicate, phosphoric acid and water; shaping (preferably extruding) the obtained shapable mixture; and drying and thereafter calcining the obtained shaped particles. A shaped composition having high crash strength is obtained by this process.

Binding and shaping of cracking catalyst fines

Provided is an improved process for removing sulfur compounds from sulfur contaminated fluid streams by contacting such fluid streams with an absorbent composition comprising zinc oxide, silica, and molybdenum disulfide. The absorbent composition comprising zinc oxide, silica, and molybdenum disulfide is a novel composition which has the desirable properties of high sulfur loading capacity and the, ability to be contacted with the hydrogen sulfide containing fluid stream for the removal of such hydrogen sulfide from said fluid stream with a minimum amount of sulfur dioxide slippage. An additional embodiment of the disclosed invention includes a method for minimizing the amount of extrusion die wear during the production of the zinc oxide based absorbent compositions. Extrusion die wear is reduced by adding a quantity of molybdenum disulfide to the zinc oxide absorbent in an amount which provides desirable lubricating properties such that extrusion die wear is reduced during the manufacture of the composition.
