Patent number: 8785340Abstract: The catalyst exhibiting hydrogen spillover effect relates to the composition of a catalyst exhibiting hydrogen spillover effect and to a process for preparing the catalyst. The catalyst has a reduced transition base metal of Group VIB or Group VIIIB, such as cobalt, nickel, molybdenum or tungsten, supported on a high porous carrier, such as saponite, the base metal being ion-exchanged with at least one precious metal of Group VIIIB. The process includes the steps of loading the base metal onto the support, reducing the base metal, preferably with H2 at 600° C., and thereafter ion-exchanging the precious metal with the base metal. Preferred examples of the catalyst include a saponite support loaded with about 10-20 wt % cobalt and about 0.1-1 wt % precious metal. The catalyst is optimized for reactions that occur in commercial processes at about 360-400° C., such as in hydrocracking.Type: GrantFiled: October 20, 2011Date of Patent: July 22, 2014Assignee: King Fahd University of Petroleum and MineralsInventors: Takuma Kimura, Mohammad Abdullah Al-Saleh, Halim Hamid Redhwi, Mohammad Ashraf Ali, Shakeel Ahmed, Masayuki Inui

Publication number: 20140190349Abstract: In a dehydration equipment, a regenerative gas heater heats a portion of CO2 gas dehydrated in an adsorption tower that is performing an adsorption process and supplies the gas to an adsorption tower that is performing a regeneration process. A regenerative gas preheater performs heat exchange between the CO2 gas that will be supplied to a regenerative gas heater and the CO2 gas sent out from the adsorption tower that is performing the regeneration process. Then, in the dehydration equipment, a regenerative gas cooler cools the CO2 gas that has been sent out from the adsorption tower that is performing the regeneration process and exchanged heat, separates water from the cooled CO2 gas, and returns the resulting gas to the adsorption tower. Thus, the dehydration equipment can prevent an increase in utility consumption due to the regeneration process.Type: ApplicationFiled: April 9, 2013Publication date: July 10, 2014Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Masayuki Inui, Takahito Yonekawa, Koji Nakayama, Tatsuya Tsujiuchi, Yoshiki Sorimachi
