    摘要： The present invention provides for a catalyst composition which is effective for use in the production of dimer products and higher olefin products from lower olefins such as propylene and butene in high yields and with an average degree of branching in the dimer products of less than about 1.6 methyl groups per molecule, generally in the range of from about 1.0 to 1.4 methyl groups per molecule. The present invention also provides a process for producing such dimer and higher olefin products using the catalyst composition of this invention. The catalyst of the invention comprises an amorphous nickel oxide (NiO) present as a disperse substantial monolayer on the surfaces of a silica (SiO.sub.2) support, which support also contains minor amounts of an oxide of aluminum, gallium or indium such that the ratio of NiO to metal oxide present in the catalyst is within the range of from about 4:1 to about 100:1. The catalyst may be prepared by precipitating a water insoluble nickel salt onto the surfaces of a silica support which has been impregnated with the metal oxide or onto a silica-alumina support which has been dealuminized such that the resulting nickel oxide/alumina ratio will fall within the ranges set forth above. The catalyst may then be activated by calcination in the presence of oxygen at a temperature within the range of from about 500.degree. to 700.degree. C.

    摘要： The present invention provides for a non-nickel-containing catalyst which is effective for use in the production of dimer products and higher olefin products from a butene starting material at relatively high conversion, good selectivity towards octene production and good activity maintenance over prolonged polymerization times. The catalyst is prepared by impregnating an amorphous trivalent metal oxide support selected from the group consisting of aluminum oxide, gallium oxide and indium oxide with a silicon-containing precursor compound which, after calcination, yields a substantial mono layer of SiO.sub.2 on the surface of the metal oxide support. A disperse layer of TiO.sub.2 is then deposited on the surface of the SiO.sub.2 monolayer by application of a solvent solution of a precursor compound containing titanium onto the SiO.sub.2 monolayer, followed by calcination to reduce the precursor titanium compound to TiO.sub.2.

    摘要： The invention concerns a method for reactive separation of mixtures containing hydrocarbons and oxygenated hydrocarbons, by contacting a mixture of hydrocarbons such as C.sub.2 to C.sub.26 hydrocarbons and mixtures thereof and oxygenated hydrocarbons, such as C.sub.2 to C.sub.40 oxygenated hydrocarbons and mixtures thereof to form a mixture of hydrocarbons and lower molecular weight oxygenated hydrocarbons and heating the mixture in water at temperature typically from about and pressure sufficient to cleave the oxygenated hydrocarbons to lower molecular weight products to form a liquid layer containing water soluble reaction products and an organic layer containing primarily hydrocarbons.

    摘要： The present invention provides for a simplified process for converting ethers into their corresponding alcohols comprising forming an aqueous mixture of the ether and at least about 50% by weight water and heating the mixture under autogeneous pressure at a temperature of from about 250.degree. to 450.degree. C., more preferably from about 250.degree. C. up to the critical temperature of water which is about 374.degree. C. Heating is continued for a period of time sufficient to convert at least about 20% by weight of the ether, usually from about 5 up to about 120 minutes, depending on temperature and the amount of water present, and the identity of the starting ether feedstock.The process may be characterized as an aquathermolysis reaction wherein the reaction proceeds in water primarily through ionic routes rather than through free radical routes. Accordingly, relatively high conversion rates and good yields of alcohol and other reaction by-products may be obtained without the necessity of using a catalyst in the process.
