    摘要: A process for reducing the polynuclear aromatics (PNA) content of a sulfur-containing hydrocarbon stream. The process includes contacting the sulfur-containing hydrocarbon stream with a dearomatization composition comprising a promoter metal component and zinc oxide. The dearomatization composition has enhanced resistance to sulfur poisoning and is also effective to remove sulfur from the hydrocarbon stream.

    摘要: Process for forming a zeolite particle in the fluidizable size range from 20 to 150 micrometers. Acid-stable, molecular sieve zeolite mordenite is formed by mixing silica-alumina gel particles in the fluidized size range with sodium silicate, sodium hydroxide, sodium chloride, and mordenite seed crystals. For example, the mixture is reacted under autogenous pressure at 180.degree. C for 24 hours.
