摘要： The present invention relates to a method for the activation of PMA based catalysts by treating the catalyst precursor with a nitrogen-containing compound such as an oxide of nitrogen gas or a nitrogen acid such as nitric or nitrous at a temperature of from about 125.degree. C. to about 400.degree. C. The method can be employed in a reactor by loading the catalyst precursor, adjusting the reactor temperature to one suitable for activation and optionally sweeping the reactor with an inert gas followed by the treating step. The method herein permits faster, lower temperature catalyst activation than when air activation is employed giving higher oxidative conversion yields and prolonged catalyst life.

摘要： In the production of benzene carboxylic acids by the oxidation of alkyl benzenes with molecular oxygen in the presence of a heavy metal oxidation catalyst, the catalyst is recovered as a residue contaminated by iron and tar-like by-products which act as inhibitors for the oxidation reaction and cannot be re-used as such. The catalyst is recovered in such a purity as re-usable by extracting the residue by water, regulating the pH of the aqueous phase to a value more than 5 but not exceeding 8 to thereby separate the tar-like products as an oily float and iron as precipitates and removing such oily float and precipitates from the aqueous phase.

The method includes (a) bringing a CoF3-containing cobalt fluoride in a reactor into contact with 3,3,3-trifluoropropene to produce a CoF2-containing cobalt fluoride and 1,1,1,2,3-pentafluoropropane, (b) transferring the CoF2-containing cobalt fluoride in the reactor to a regenerator and bringing the transferred CoF2-containing cobalt fluoride into contact with fluorine gas to regenerate a CoF3-containing cobalt fluoride, and (c) transferring the CoF3-containing cobalt fluoride in the regenerator to the reactor and employing the transferred CoF3-containing cobalt fluoride in Operation (a). Accordingly, the 1,1,1,2,3-pentafluoropropane can be continuously produced with high yield from the 3,3,3-trifluoropropene using a cobalt fluoride (CoF2/CoF3) as a fluid catalyst, thereby improving the reaction stability and readily adjusting the optimum conversion rate and selectivity.

摘要： A process for recovering double metal cyanide complex catalyst from a polymer such as polypropylene glycol in a form suitable for use as a polymerization catalyst is described. The process comprises the steps of (a) combining the polymer with a non-polar solvent to precipitate the catalyst and (b) filtering the resulting mixture in the presence of a filter aid to separate the polymer from the precipitated catalyst. In contrast to the prior art methods of catalyst removal, the process of the invention yields polymer uniformly low in color as well as recovered catalyst which may be reused in subsequent polymerizations.

摘要： Provided is a method of reactivating a used titania catalyst for hydrogenation treatment, capable of improving the catalytic activity of the used titania catalyst for hydrogenation treatment that is obtained by supporting a catalyst component on a titania support and exhibits reduced catalytic activity after having been used for hydrogenation treatment of a hydrocarbon oil, to a level comparable to that of a newly prepared fresh titania catalyst before use. The method of reactivating a used titania catalyst for hydrogenation treatment, the used titania catalyst for hydrogenation treatment being obtained by supporting a catalyst component on a titania support and exhibiting reduced catalytic activity after having been used for hydrogenation treatment of a hydrocarbon oil, includes: a coke removal step of removing a carbonaceous component on a surface of the used catalyst by heating the catalyst in an oxygen-containing gas atmosphere; an impregnation step of impregnating the carbonaceous component-removed catalyst obtained by the coke removal step with a saccharide-containing solution; and a drying step of drying the saccharide-impregnated catalyst obtained by the impregnation step, to obtain a catalyst in which a saccharide is supported.
