Abstract:
A method for deoxygenating renewable oils comprised of natural oils or greases or derivatives thereof containing triglycerides or free fatty acids includes the steps of: providing a catalyst comprising a support predominantly comprised of alumina with metal compounds provided on the support based on Mo and at least one selected from the group consisting of Ni and Co, and at least one selected from the group consisting of Cu and Cr, and contacting the renewable oils with the catalyst under conditions sufficient to deoxygenate the renewable oils.
Abstract:
A catalyst for removal of NOx from exhaust gas, containing cerium oxide and titanium dioxide, wherein a first portion of the cerium oxide forms at least one agglomerate of cerium oxide crystallites interdispersed in the titanium dioxide, and a second portion of the cerium oxide forms at least one island on a surface of the titanium dioxide, a method for producing the catalyst, a process for selectively reducing NOx levels in an exhaust gas using the catalyst, and an SCR canister containing the catalyst therein.
Abstract:
A process for the conversion of a feed comprising a mixture of hydrogen and carbon monoxide to hydrocarbons, the hydrogen and carbon monoxide in the feed being present in a ratio of from 1:9 to 9:1 by volume, the process comprising the step of contacting the feed at elevated temperatures and atmospheric or elevated pressure with a catalyst comprising titanium dioxide and cobalt wherein the catalyst initially comprises from 30% to 95% metallic cobalt by weight of cobalt.
Abstract:
The invention relates to a catalyst for decomposing nitrous oxide, to a method for producing same, and to the use thereof. The catalyst contains rhodium on a catalyst support, and the catalyst support is produced by mixing zirconium dioxide powder with a silicon compound as a binder and water so as to form a kneadable mass, homogenizing the mass, molding the mass into molded bodies, drying, and calcining. The binder is selected from silicon compounds of the general formula (I) to (IV) (Hal)xSiR4-x(l) (Hal)xSi(OR')4-x(II) (Hal)xSi(NR R )a-x(III) RxSi(OR')4-x (IV) RxSi(NR R )4-x(V) (R O)xSi(NR R )4-x(VI), where Hal independently of one another represents halogen (F, Cl, Br, or I), R independently of one another represents H or an optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, arylalkyl, or aryl group, R , R independently of one another represent H or an optionally substituted alkyl, acyl, arylalkyl, or aryl group, and x represents 0 to 4.

Abstract:
The purpose of the present invention is to provide silanol compounds that can be used as raw materials of siloxane compounds and the like, and a composition of the silanol compounds, as well as to provide a production method that makes it possible to produce silanol compounds at excellent yield. A composition comprising 5 mass% to 100 mass% of a silanol compound represented by Formulas (A) to (C) can be prepared by devising to produce silanol compounds under water-free conditions, to produce silanol compounds in a solvent having the effect of suppressing the condensation of silanol compounds, and to perform other such processes, the composition being able to be used as a raw material or the like of siloxane compounds because the silanol compounds can be stably present in the resulting composition.
Abstract:
The structure (102, 302, 402, 502, 602, 702, 802, 902) comprises one or more segments (404, 604) having axially oriented substantially parallel fluid flow passages (110, 304, 410, 510, 610,710,810,910); cell walls (112, 312, 412, 512, 612, 712, 812, 912) between adjacent fluid flow passages, each cell wall having at least two opposite cell wall surfaces, and comprising (in or on a cell wall surface) at least one active compound that can interact with a fluid contained within or passed through the passages; and a plurality of axially continuous, axially oriented, filaments (114, 314, 414, 514, 614,714, 814,914) that are thermally and/or electrically conductive for transfer of thermal energy from the active compound. According to the invention the filaments are embedded within the cell walls in direct contact with the active compound on or in the cell wall surface, and can transfer thermal energy between the active compound and the conductive filaments.
