Patent number: 8703641Abstract: In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of the metal precursor feeds end up in the supernatant. The metals can be recovered via any of chemical precipitation, ion exchange, electro-coagulation, and combinations thereof to generate an effluent stream containing less than 50 mole % of metal ions in at least one of the metal residuals, and for at least one of the metal residuals recovered as a metal precursor feed for use in the co-precipitation reaction. In one embodiment, the resin functions as an anion exchange resin with an acidic supernatant to recover Group VIB metal residuals, and a cation exchange resin with a basic supernatant to recover Promoter metal residuals. An effluent stream from the process to waste treatment contains less than 50 ppm metals.Type: GrantFiled: October 18, 2011Date of Patent: April 22, 2014Assignee: Chevron U.S.A.

Patent number: 8701393Abstract: An internal combustion engine in which an SOx trap catalyst (13) for trapping SOx contained in the exhaust gas contains an oxygen adsorbing and releasing material (54) which can adsorb SO2 contained in the exhaust gas and an SOx storage material (55) which can store SOx in the form of sulfates. The SO2 which is contained in the exhaust gas is chemically adsorbed at the oxygen adsorbing and releasing material (54) without being oxidized. If the temperature of the SOx trap catalyst (13) becomes higher than the start temperature of adsorbed SO2 movement, the SO2 which is chemically adsorbed at the oxygen adsorbing and releasing material (54) is oxidized and stored in the form of sulfates in the SOx storage material (55).Type: GrantFiled: July 23, 2009Date of Patent: April 22, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takamitsu Asanuma, Yoshihisa Tsukamoto, Kazuhiro Umemoto, Junichi Matsuo, Hiromasa Nishioka
