Patent number: 6919016Abstract: A process is disclosed for preparing a C4 stream for feeding to an alkylation process which reacts isobutane with butene to produce isooctane. The C4 stream is treated in a first distillation column reactor to remove dienes and mercaptans and separate out any C5's which might be present. The treated C4's are then fed to a second distillation column reactor that concurrently isomerizes 1-butene to 2-butene and splits the normal C4's from the iso C4's. The iso C4's are then fed to a third distillation column reactor where a portion of the isobutene is saturated to isobutane. The C4's from the isomerization/splitter are combined with the C4's from the hydrogenation unit and fed to a cold acid alkylation unit. The third distillation column may also oligomerize a portion of the isobutene to diisobutene in the upper end which is saturated in the bottom of the column to isooctane.Type: GrantFiled: August 5, 2004Date of Patent: July 19, 2005Assignee: Catalytic Distillation TechnologiesInventors: Gary G.

Patent number: 6676830Abstract: A process for the desulfurization of a light boiling range (C5-350° F.) fluid catalytically cracked naphtha, which may be first subjected to a thioetherification to react the diolefins with mercaptans contained in it to form sulfides, is fed to a high pressure (>250 psig) catalytic distillation hydrodesulfurization step along with hydrogen under conditions to react most of the organic sulfur compounds, including sulfides from the thioetherification to form H2S. The H2S and a light product stream (C5's and C6's) are removed as overheads. The bottoms from the catalytic distillation hydrodesulfurization step is fractionated and the bottoms from the fractionation contacted with hydrogen in a straight pass hydrogenation step in the presence of a hydrodesulfurization catalyst at pressure of >250 and temperature >400° F. to further reduce the sulfur content.Type: GrantFiled: September 17, 2001Date of Patent: January 13, 2004Assignee: Catalytic Distillation TechnologiesInventors: Montri Vichailak, Bertrand Klussman, Mario J.

Patent number: 6416658Abstract: A process for concurrently fractionating and hydrotreating of a full range naphtha stream. The full boiling range naphtha stream is subjected to simultaneous hydrodesulfurization and splitting into a light boiling range naphtha and a heavy boiling range naphtha, which have been treated to covert mercaptans in the fractions to H2S, which is separated with and separated from the light naphtha wherein the improvement is a further hydrodesulfurization by contacting the light boiling range naphtha with hydrogen in countercurrent flow in a fixed bed of hydrodesulfurization catalyst to remove recombinant mercaptans which are formed by the reverse reaction of H2S with olefins in the naphtha during the initial hydrodesulfurization.Type: GrantFiled: October 19, 2000Date of Patent: July 9, 2002Assignee: Catalytic Distillation TechnologiesInventors: Mario J.
