摘要： The present invention relates to a process for preparing ethers, particularly unsymmetrical ethers, and preferably ethers suitable for use as base stocks for lubricant compositions. In particular, the process involves the reaction of a branched-chain aldehyde and a branched-chain alcohol to form an enol ether and conversion of the enol ether to a saturated ether by reduction.

摘要： The present invention provides a process for the hydrogenation of polyunsaturated hydrocarbon compounds, in particular di-olefins and alkynes, more particularly di-olefins, said process comprising contacting a feed comprising one or more polyunsaturated hydrocarbon compounds with a catalyst comprising copper and carbon in the presence of hydrogen, preferably wherein the catalyst is a copper catalyst on a carbon-containing support. The present invention also provides a process for producing a copper catalyst on a carbon-containing support and the use of a copper catalyst on a carbon-containing support to increase the selectivity towards di-olefin hydrogenation over mono-olefin hydrogenation in a process for hydrogenation of one or more di-olefins.

摘要： The present invention provides a process for upgrading a Fischer-Tropsch product by hydrocracking in the presence of a hydrocracking catalyst in a reactor, wherein the process is initiated by a series of steps (i) to (iv). The hydrocracking catalyst is (i) contacted with a hydrogen-containing stream having a feed temperature of from 360° C. to 420° C.; (ii) the feed temperature of the hydrogen-containing stream is reduced to a temperature of from 220° C. to 280° C.; (iii) the catalyst is contacted with a Fischer-Tropsch product stream having a feed temperature of from 220° C. to 280° C., which is co-fed with the hydrogen-containing stream; and (iv) the catalyst is co-fed with a Fischer-Tropsch product stream and hydrogen-containing stream having feed temperatures of from 380° C. and 400° C. for at least four days and wherein the hydrocracking catalyst is not activated by sulfiding.
