Patent number: 10682634Abstract: A method of manufacturing a modified zeolite catalyst may include reacting a zeolite with a metal salt to form a zeolite/metal salt complex. The zeolite may be a ZSM-5 or ZSM-11. The method may include heating the zeolite/metal salt complex to form an intermediate modified zeolite, and reacting the intermediate modified zeolite with an acid. The method may include ion exchanging the intermediate modified zeolite following the reaction with the acid to form a modified zeolite catalyst.Type: GrantFiled: March 27, 2015Date of Patent: June 16, 2020Assignee: REACTION 35, LLCInventor: Peter K. Stoimenov

Patent number: 10322987Abstract: A method includes brominating a butanes feed stream including i-butane in a bromination reactor to form a bromination effluent stream including t-butyl bromide. The method includes dehydrobrominating the t-butyl bromide to form isobutylene. Another method includes brominating a mixed pentanes feed stream including i-pentane and n-pentane in a bromination reactor to form a bromination effluent stream including t-pentyl bromide. The method includes dehydrobrominating the t-pentyl bromide to form isoamylene and HBr.Type: GrantFiled: June 27, 2018Date of Patent: June 18, 2019Assignee: REACTION 35, LLCInventors: Jeffrey H. Sherman, Peter K. Stoimenov

Patent number: 10016701Abstract: A method includes injecting a feed stream including a hydrogen halide and water into a vapor liquid separator. The feed stream has a liquid phase and a vapor phase. The method further includes separating the liquid phase and the vapor phase in the vapor liquid separator to form condensate and vapor, and discharging the condensate from the vapor liquid separator in a liquid stream. The method also includes discharging the vapor from the vapor liquid separator in a vapor stream.Type: GrantFiled: May 28, 2014Date of Patent: July 10, 2018Assignee: Reaction 35, LLCInventor: Philip Grosso

Patent number: 9771308Abstract: Olefins and diolefins, such as 1,3-butiadiene, may be produced by a method utilizing a series of bromination and dehydrobromination reactions. Bromine may be reacted with n-butane to form dibromobutane. The dibromobutanes may be dehydrobrominating to form 1,3-butadiene. The method may include reacting butene with bromine to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with hydrogen bromide in the presence of oxygen to form bromobutenes, and dehydrobrominating the bromobutenes to form 1,3-butadiene. The method may include reacting butene with bromine to form dibromobutanes, and dehydrobrominating the dibromobutanes to form 1,3-butadiene.Type: GrantFiled: June 9, 2015Date of Patent: September 26, 2017Assignee: REACTION 35, LLCInventors: Peter K. Stoimenov, Jeffrey H. Sherman

Patent number: 9045385Abstract: A process is disclosed that includes brominating a C2, C3, C4, C5 or C6 alkane with elemental bromine to form a bromo-alkane. The bromo-alkane is reacted to form a C2, C3, C4, C5 or C6 alkene and HBr. The HBr is oxidized to form elemental bromine.Type: GrantFiled: December 12, 2014Date of Patent: June 2, 2015Assignee: REACTION 35, LLCInventors: Vivek Julka, Sagar Gadewar, Peter K. Stoimenov, Philip Grosso, Jeffrey H. Sherman, Aihua Zhang, Eric W. McFarland
