    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.

    摘要: In a method of synthesizing a silicoaluminophosphate molecular sieve having 90+% CHA framework-type character, a reaction mixture is prepared comprising sources of water, silicon, aluminum, and phosphorus, as well as an organic template. In one aspect, the reaction mixture is heated at more than 10° C./hour to a crystallization temperature and is retained at the crystallization temperature or within the crystallization temperature range for a crystallization time from 16 hours to 350 hours to produce the silicoaluminophosphate molecular sieve. In another aspect, the reaction mixture is heated at less than 10° C./hour to a crystallization temperature from about 150° C. to about 225° C. and is then retained there for less than 10 hours to produce the silicoaluminophosphate molecular sieve. The molecular sieve can then be recovered from the reaction mixture and, preferably, used in a hydrocarbon conversion process, such as oxygenates to olefins.
