Publication number: 20180201554Abstract: A process for the production of jet and other heavy fuels from alcohols and mixture of alcohols is disclosed. The process may include contacting in a reaction zone at least one C2 to C11 alcohol with a solid catalyst having activity for the simultaneous dehydration of the alcohols to form olefins, isomerization of the olefins to form internal olefins, and oligomerization of the olefins produced in situ via the dehydration reaction to form an effluent comprising mono-olefinic hydrocarbons. Preferably, the alcohol feed is a mixture of alcohols, such as C2 to C7 alcohols or C4 and C6 alcohols, enabling the production of a mixture of branched hydrocarbons that may be used directly as a jet fuel without blending.Type: ApplicationFiled: March 12, 2018Publication date: July 19, 2018Applicant: Lummus Technology Inc.Inventors: Marvin I. Greene, Ruozhi Song, Arvids Judzis, JR.

Patent number: 8101810Abstract: A process for reformate benzene reduction, the process including: feeding a light reformate fraction, an olefin feed, and an alkylation catalyst to an alkylation reaction zone; contacting the light reformate fraction and the olefin feed in the presence of the alkylation catalyst in the alkylation reaction zone to convert at least a portion of the benzene and the olefin to a monoalkylate; recovering a catalyst fraction from an alkylation reaction zone effluent; and recovering a light reformate product having a reduced benzene content.Type: GrantFiled: August 20, 2008Date of Patent: January 24, 2012Assignee: Catalytic Distillation TechnologiesInventors: Christopher C. Boyer, Lawrence A. Smith, Jr., Arvids Judzis, Jr., John R. Adams

Patent number: 7431827Abstract: A process for the production of low sulfur, low olefin gasoline wherein a cracked naphtha, such as a full boiling range cracked naphtha, is first separated by fractional distillation into at least two fractions while simultaneously selectively hydrogenating the polyunsaturated compounds contained therein. The mono olefins in the light fraction are then subjected to etherification with alcohol to produce ethers or hydration with water to produce alcohols. The heavy fraction is subjected to sulfur removal by hydrodesulfurization or chemisorption. The two fractions are then combined to produce a low sulfur, low olefin gasoline.Type: GrantFiled: October 27, 2004Date of Patent: October 7, 2008Assignee: Catalytic Distillation TechnologiesInventors: Kerry L. Rock, Yi-Gang Xiong, Arvids Judzis, Jr.

Patent number: 7320745Abstract: An energy efficient process scheme for a highly exothermic reaction-distillation system in which the reactor is external to the distillation column and the feed to the reactor is a mixture of at least one liquid product stream from the distillation column with or without other liquid/vapor reactants. The reactor is operated under adiabatic and boiling point conditions and at a pressure that results in vaporizing a portion of the liquid flow through the reactor due to the heat of reaction. Under these conditions, reaction temperature is controlled by reactor pressure. The pressure (and hence the temperature) is maintained at a sufficiently high level such that the reactor effluent can be efficiently used to provide reboil heat for the distillation column.Type: GrantFiled: January 19, 2005Date of Patent: January 22, 2008Assignee: Catalytic Distillation TechnologiesInventors: Arvids Judzis, Jr., Abraham P. Gelbein, John R. Adams, Christopher C. Boyer
