Patent number: 10478773Abstract: The invention is related to the sphere technologies for desulfurization and demercaptanization of gaseous hydrocarbons. It can be used for purification of any gaseous hydrocarbon medium. The device includes a catalytic reactor loaded with a catalyst solution in an organic solvent, a means of withdrawal sulfur solution from the reactor into the sulfur-separating unit, and a sulfur-separating unit. The sulfur-separation unit includes a means of sulfur extraction. The reactor design and the catalyst composition provide conversion of at least 99.99% of hydrogen sulfide and mercaptans into sulfur and disulfides. The catalyst is composed of mixed-ligand complexes of transition metals. The technical result achieved by use of claimed invention is effectively a single-stage purification of gaseous hydrocarbons from hydrogen sulfide and mercaptans with remaining concentration of —SH down to 0.001 ppm while leaving no toxic waste.Type: GrantFiled: January 9, 2019Date of Patent: November 19, 2019Assignee: START-CATALYST LLCInventors: Liudmila Aleksandrovna Tyurina, Alexander Ivanovich Tyurin, Irina Gennadievna Tarkhanova, Alexey Aleksandrovich Tyurin

Patent number: 10427095Abstract: This application is in the field of technologies for desulfurization and demercaptanization of gaseous hydrocarbons. The device includes a catalytic reactor loaded with a catalyst solution in an organic solvent, a means of withdrawal sulfur solution from the reactor into the sulfur-separating unit, and a sulfur-separating unit. The said device has at least means of supplying gaseous hydrocarbon medium to be purified and oxygen-containing gas into the reactor, and a means of outletting the purified gas from the reactor. The sulfur-separation unit includes a means of sulfur extraction. The reactor design and the catalyst composition provide conversion of at least 99.99% of hydrogen sulfide and mercaptans into sulfur and disulfides. The catalyst is composed of mixed-ligand complexes of transition metals. The technical result achieved by use of claimed invention is single-stage purification of gaseous hydrocarbons from hydrogen sulfide and mercaptans with remaining concentration of —SH down up to 0.001 ppm.Type: GrantFiled: December 17, 2018Date of Patent: October 1, 2019Assignee: START-CATALYST LLCInventors: Liudmila Aleksandrovna Tyurina, Alexander Ivanovich Tyurin, Irina Gennadievna Tarkhanova, Alexey Aleksandrovich Tyurin
