Publication number: 20080153689Abstract: Systems and methods of reducing carbon dioxide emissions in a fluid catalytic cracking unit having a reactor and a regenerator at gasification conditions are disclosed. In one example, a method comprises compressing a first gas at an inlet pressure to a predetermined high pressure to define a compressed gas and combusting a second gas with the compressed gas to a predetermined temperature to define a heated gas. The method further comprises expanding the heated gas to a predetermined low pressure to define a feed gas. The method further comprises introducing the feed gas to the regenerator. The feed gas, now at an elevated temperature, provides heat to the regenerator to burn coke off spent catalyst from the reactor, achieving a proportion of carbon monoxide in a flue gas. In turn, this reduces the concentration of carbon dioxide in the flue gas.Type: ApplicationFiled: December 21, 2006Publication date: June 26, 2008Inventors: Gavin P. Towler, Douglas N. Rundell

Publication number: 20080152549Abstract: A preheating process is provided for a regenerator in a fluid catalytic cracking system having a reactor and a regenerator at oxidative conditions. A first gas stream containing oxygen at an inlet pressure is compressed to a pressure of at least about 10 atm to produce a compressed gas stream. A second gas stream containing a fuel source is combusted with the compressed gas stream to produce a heated gas stream. The heated gas stream is expanded to a predetermined low pressure to produce a feed gas stream. The feed gas stream is introduced into the regenerator in the fluidized catalytic cracking system.Type: ApplicationFiled: December 21, 2006Publication date: June 26, 2008Inventors: Gavin P. Towler, Douglas N. Rundell

Publication number: 20020175107Abstract: Aromatic blendstocks suitable for use in making an unleaded gasoline fuel for combustion in a spark ignition engine contain substantial amounts of diisopropylbenzene which provides relatively more energy for doing work while producing fewer carbon dioxide emissions as compared to current gasoline blendstocks. Unleaded gasolines made utilizing the foregoing aromatic blendstocks contain at least about 0.3 weight percent diisopropylbenzene, preferably about 0.3 to about 10 weight percent diisopropylbenzene.Type: ApplicationFiled: February 20, 2001Publication date: November 28, 2002Inventors: George A.

Patent number: 6048451Abstract: 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.Type: GrantFiled: January 14, 1997Date of Patent: April 11, 2000Assignee: BP Amoco CorporationInventors: George A.
