摘要:
This CO shift catalyst, which reforms carbon monoxide (CO) present in a gas, comprises the following: an active component containing a primary component, namely either molybdenum (Mo) or iron (Fe), and a secondary component, namely either nickel (Ni) or ruthenium (Ru); and a complex-oxide support that supports the active component. Said complex-oxide support comprises two or more of the following: titanium (Ti), zirconium (Zr), cerium (Ce), silicon (Si), aluminum (Al), and lanthanum (La).
摘要:
Shale oils having a high sulfur content are hydrotreated in a two stage process. The shale oil feed is passed along with hydrogen to a reactor (3) where it contacts a catalyst in a first stage (12) to effect desulfurization. The feed is then passed to a second stage (13) where it contacts a second catalyst to effect denitrogenation. The catalyst in the first stage is cobalt and/or nickel and molybdenum supported on a rare earth oxide-modified alumina. The catalyst in the second stage is cobalt and/or nickel, molybdenum, and a promoter on a zeolite and rare earth oxide-modified alumina support.

摘要:
Hydrodesulfurization of cracked naphtha, with minimum attendant hydrogenation of olefins, is effected over a sulfided carbon support catalyst bearing (i) a non-noble Group VIII metal, (ii) a Group VI-B metal, and (iii) a metal of Group IA, II A, III A, or the lanthanide Group of rare earths.
摘要:
In order to increase performances of an iron oxide-potassium oxide system catalyst to be used for an alkyl aromatic hydrocarbon dehydrogenation reaction in the presence of steam, there is provided an alkyl aromatic hydrocarbon dehydrogenation catalyst wherein a little amount of titanium oxide is added by the mixing and kneading method or by the preceding addition to iron oxide in the production of the iron oxide-potassium oxide system catalyst to be used for the alkyl aromatic hydrocarbon dehydrogenation reaction in the presence of steam. The iron oxide-potassium oxide system catalyst is allowed to contain a little amount of titanium oxide, whereby an activity can be remarkably increased, as well as a selectivity in the same conversion ratio can also be improved in the alkyl aromatic hydrocarbon dehydrogenation reaction, and further the obtained catalyst exhibits stable performances with time on stream.
