Patent number: 9365535Abstract: The invention provides a process for the preparation of an alkylene glycol from an alkene. A gas composition from an alkylene oxide reactor is supplied to an alkylene oxide absorber comprising a column of vertically stacked trays or comprising a packed column. Lean absorbent comprising at least 20 wt % water is supplied to the alkylene oxide absorber and is contacted with the gas composition in the presence of one or more catalysts that promote carboxylation and hydrolysis. At least 50% of the alkylene oxide entering the alkylene oxide absorber is converted in the alkylene oxide absorber. Fat absorbent is withdrawn from the absorber, is optionally supplied to finishing reactors and/or a flash vessel or light ends stripper, and is subsequently subjected to dehydration and purification to provide a purified alkylene glycol product stream.Type: GrantFiled: January 13, 2014Date of Patent: June 14, 2016Assignee: Shell Oil CompanyInventors: Eugene Marie Godfried Andre Van Kruchten, Dominicus Maria Rekers, Mathias Jozef Paul Slapak

Patent number: 8088344Abstract: A multi-tubular reactor system for catalytically reacting a fluid reactant mixture to form a fluid product comprising a shell and a plurality of reactor tubes housed therein. The reactor system is adapted to allow heat-exchange fluid to flow between the shell and the external surface of the reactor tubes. A reactor tube comprises a reaction zone, and also a heating zone and/or a cooling zone. The reaction zone is positioned downstream of the heating zone. The cooling zone is positioned downstream of the reaction zone. The reactor tube contains a bed of solid particulate catalyst in the reaction zone. The reactor tube additionally contains a heat-exchanging essentially rod-shaped insert having a length of from 1 to 20%, preferably 1 to 5%, of the total length of the reactor tube in the heating zone and/or the cooling zone.Type: GrantFiled: September 22, 2006Date of Patent: January 3, 2012Assignee: Shell Oil CompanyInventors: Arend Jan Te Raa, Mathias Jozef Paul Slapak, Alouisius Nicolaas Rene Bos

Publication number: 20080154051Abstract: The present invention relates to an improved epoxidation process and an improved epoxidation reactor. The present invention makes use of a reactor which comprises a plurality of microchannels. Such process microchannels may be adapted such that the epoxidation and optionally other processes can take place in the microchannels and that they are in a heat exchange relation with channels adapted to contain a heat exchange fluid. A reactor comprising such process microchannels is referred to as a “microchannel reactor”. The invention also provides a method of installing an epoxidation catalyst in a microchannel reactor. The invention also provides a method of preparing an epoxidation catalyst. The invention also provides an epoxidation catalyst. The invention also provides a certain process for the epoxidation of an olefin and a process for the preparation of a chemical derivable from an olefin oxide. The invention also provides a microchannel reactor.Type: ApplicationFiled: December 20, 2006Publication date: June 26, 2008Inventors: Jeroen Willem Bolk, Alouisius Nicolaas Renee Bos, Wayne Errol Evans, John Robert Lockemeyer, Paul Michael Mcallister, Bernardus Franciscus Josef Marie Ramakers, Dominicus Maria Rekers, Mathias Jozef Paul Slapak
