    摘要: In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone comprising a catalyst system which comprises a molecular sieve and at least one hydrogenation metal. The MCM-22 family molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom, and the hydrogenation metal is selected from the group consisting of palladium, ruthenium, nickel, zinc, tin, cobalt, and combinations of any two or more thereof. Hydroalkylation conditions of temperature and pressure are selected to produce a hydroalkylation conversion in a range of from about 15% to about 75% The benzene and hydrogen are then contacted in the at least one reaction zone under said selected hydroalkylation condition to produce an effluent containing cyclohexylbenzene.

    摘要: Disclosed herein are processes for alcohol production by reducing an esterification product, such as ethyl acetate. The processes comprise esterifying acetic acid and an alcohol such as ethanol to produce an esterification product. The esterification product is reduced with hydrogen in the presence of a catalyst to obtain a crude reaction mixture comprising the alcohol, in particular ethanol, which may be separated from the crude reaction mixture. Ethyl acetate from the crude reaction mixture may be recovered as returned to assist in recovering the esterification product.

    摘要: A process is provided for making a reaction product comprising 1-butanol by contacting a reactant comprising ethanol containing a significant amount of water with a decomposed hydrotalcite catalyst. The catalyst may be 1) hydrotalcites which have been thermally decomposed, either partially or fully, to form catalytically active species; 2) combinations of hydrotalcites (optionally containing transition metals) and metal carbonates; and 3) hydrotalcites (optionally containing transition metals) surface-impregnated with a transition metal nitrate, where catalysts 2) and 3) have also been thermally decomposed, either partially or fully, to form catalytically active species. The catalyst, at a selected reaction time, has greater activity when the ethanol contains water as compared to when the ethanol is anhydrous.
