Abstract: A product of reduced sulfur content is produced from a feedstock which is comprised of a mixture of hydrocarbons and contains organic sulfur compounds as unwanted impurities. The process comprises converting at least a portion of the sulfur-containing impurities to sulfur-containing products of higher boiling point by treatment with an alkylating agent in the presence of an acid catalyst and removing at least a portion of these higher boiling products by fractional distillation. Suitable alkylating agents include alcohols and olefins. In a preferred embodiment, catalytic cracking products which contain aromatic sulfur compounds as impurities are used as a feedstock for the process.

Abstract: Compositions comprising certain metal-containing materials distributed interactively on a deboronated HAMS-1B crystalline borosilicate molecular sieve which are useful for catalytically oxidizing or oxidatively dehydrogenating organic compounds such as alkanes, aromatics, and alkyl-substituted aromatics are described. Alkanes are oxidatively dehydrogenated to olefins, and an aromatic compound such as benzene can be oxidized by nitric and/or nitrous oxide to largely phenol or largely nitrobenzene depending upon the oxidation temperature. When the compound is a methylaromatic, oxidation produces an aromatic aldehyde. Alkyl groups larger than methyl oxidatively dehydrogenate to alkenyl groups. The compositions can be used in a process to separate p-xylene from a mixture of its isomers based upon the ability of the compositions, which preferably comprise a iron molybdenum material interactively distributed on a deboronated HAMS-1B crystalline borosilicate molecular sieve, to selectively oxidize the p-xylene to an aldehyde or dialdehyde while not substantially oxidizing the ortho and metaxylene isomers. Such partially oxidized mixtures of p-xylene are useful to make TPAA or as feeds to a water-based, further oxidation to make terephthalic acid. Carbon dioxide used as a carrier gas with a methylaromatic feed to the oxidation catalyst is shown to have a beneficial effect on yield and selectivity.

Abstract: In a catalytic cracking process wherein the cracking catalyst is poisoned and contaminated by metal present in the feedstock, an improved process for the removal of such metal poisons as nickel, iron and/or vanadium is employed which comprises contacting a regenerated and sulfided catalyst with an oxygen-containing gas in a defined temperature range of from about 525.degree. F. to about 725.degree. F. and washing at least a portion of the metal poisons from the catalyst. A preferred wash solution is a reductive wash medium comprising a saturated, aqueous solution of SO.sub.2. The vanadium and nickel metals may be recovered from the resultant used wash solution for possible metallurgical use. The washed catalyst may also be subjected to subsequent oxidative washes such as a hydrogen peroxide wash prior to its return to the catalytic cracking process.
