    摘要: Long chain alkyl substituted aromatic compounds, particularly alkylated naphthalenes, are produced by the alkylation of aromatics, e.g. naphthalene, with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of a zeolite alkylation catalyst, preferably a large pore size zeolite such as zeolite Y and in the presence of from about 0.5 to 3.0 weight percent water, preferably 1.0 to 3.0 weight percent. The use of the water co-feed increases the selectivity of the alkylation for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products and also increases activity and catalyst stability.

    摘要: An improved catalyst composition is disclosed for converting synthesis gas to hydrocarbon mixtures. The catalyst comprises an iron-containing, Fischer-Tropsch catalyst and a crystalline zeolite having a silica-to-alumina ratio of greater than 200 (including zeolites containing essentially no alumina) and an (R.sub.2 O+M.sub.2 /.sub.n O):SiO.sub.2 rate of less than 1.1:1 where M is a metal other than a metal of Group IIIA, n is the valence of said metal, and R is an alkyl ammonium radical, said organosilicate being characterized by a specified x-ray diffraction pattern.

    摘要: An improved method for preparing a crystalline aluminosilicate zeolite having uniform pores and greater than 40 percent crystallinity which comprises forming a critical reaction mixture containing a source of at least two cations, silica, alumina and water, wherein at least about 70 weight percent of the alumina is provided to the reaction mixture by an alumina-containing clay being added thereto, and maintaining the reaction mixture at a temperature and pressure for a time necessary to crystallize the crystalline aluminosilicate from the reaction mixture. It is desirable to preform said reaction mixture into discrete particles such as pellets or extrudates which retain their shape and acquire substantial strength in the crystallization process.
