20130175202 | HYDROCRACKING CATALYST FOR HYDROCARBON OIL, METHOD FOR PRODUCING HYDROCRACKING CATALYST, AND METHOD FOR HYDROCRACKING HYDROCARBON OIL WITH HYDROCRACKING CATALYST - The present invention relates to a hydrocracking catalyst for hydrocarbon oil comprising a support containing a framework-substituted zeolite-1 in which zirconium atoms and/or hafnium atoms form a part of a framework of an ultrastable y-type zeolite and a hydrogenative metal component carried thereon and a method for producing the same. The hydrocracking catalyst of the present invention makes it easy to diffuse heavy hydrocarbon oils such as VGO, DAO and the like into mesopores, is improved in a cracking activity and makes it possible to obtain a middle distillate at a high yield as compared with catalysts prepared by using zeolite comprising titanium and/or zirconium carried thereon. | 07-11-2013 |
20110217787 | CONCENTRATION MEASURING APPARATUS FOR HYDROGEN SULFIDE IN GAS FLOW, AND METHOD FOR DETERMINING SULFIDE ION - A concentration measuring apparatus for hydrogen sulfide includes an absorbing liquid that can absorb gaseous hydrogen sulfide as sulfide ion; a hollow fiber membrane contactor that contacts a gas flow with a flow of the absorbing liquid through a membrane, so that the absorbing liquid absorbs gaseous hydrogen sulfide in the gas flow as sulfide ion; a pump for a first channel that feeds the absorbing liquid to the hollow fiber membrane contactor; an oxidizer that exothermically reacts with sulfide ion; a pump for a second channel that feeds the oxidizer to the absorbing liquid; a first thermometer that measures a temperature of the absorbing liquid before the sulfide ion that the absorbing liquid has absorbed exothermically reacts with the oxidizer; and a second thermometer that measures the temperature of the absorbing liquid after the sulfide ion that the absorbing liquid has absorbed exothermically reacts with the oxidizer. | 09-08-2011 |
