    摘要: Ethane is converted to LPG and gasoline and/or aromatics concentrate in a combination process which comprises directly passing olefin effluent from the thermal cracking of ethane over a special crystalline aluminosilicate zeolite of the ZSM-5 type and recovering aromatics and C.sub.3 + hydrocarbons. For best yields, the thermal cracking step is conducted under more severe conditions than are used when ethylene production is optimized. The second, olefin conversion step is carried out at either the same pressure as the cracking step or higher. The process is of particular interest where low cost ethane is available.

    摘要: A process for the co-production of 2-alkanones having at least five carbon atoms and phenol or a substituted phenol. In the first step, benzene or a substituted benzene is alkylated with an alkyl moiety of at least five carbon atoms to selectively produce the 2-arylalkane isomer. Subsequent oxidation to the hydroperoxide and acid cleavage thereof yields the desired product. The alkylation step is carried out in the presence of a novel class of selective crystalline zeolite materials having pore openings with a major dimension of six to seven angstroms.

    摘要: Living plants and animals synthesize and often accumulate a wide variety of organic materials having a molecular weight greater than 150. These include different chemical types such as natural hydrocarbons including rubbery substances, natural resins, and natural glycerides such as oils and fats. These substances, formed in the anabolic process, are collectively called "anabolites".This invention provides a process for catalytically converting certain anabolites to liquid hydrocarbons useful for the manufacture of fuels such as gasoline and chemicals such as para-xylene. Crystalline aluminosilicate zeolites having an effective pore size of greater than about 5 Angstrom units are useful catalysts.
