Patent number: 5863419Abstract: 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. The process can be carried out in a distillation column reactor wherein the acid catalyzed reaction and fractional distillation are carried out simultaneously. Suitable alkylating agents include alcohols and olefins.Type: GrantFiled: August 18, 1997Date of Patent: January 26, 1999Assignee: Amoco CorporationInventors: George A. Huff, Jr., Ozie S. Owen, Bruce D. Alexander, Douglas N. Rundell, William J. Reagan, Jin S. Yoo

Patent number: 5254781Abstract: An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen for the methane coupling process can provide refrigerant nitrogen to liquify one or more of methane, ethylene and propylene which can be used in the cryogenic separation of the C.sub.2 + hydrocarbon products in the cracking process effluent.Type: GrantFiled: December 31, 1991Date of Patent: October 19, 1993Assignee: Amoco CorporationInventors: Narasimhan Calamur, George A. Huff, Jr., Harold A. Lindahl
