1,204,945. Hydrocarbon conversion catalysts. TEXACO DEVELOPMENT CORP. 31 May, 1968 [16 June, 1967], No. 26276/68. Heading B1E. [Also in Divisions C3 and C5] A catalyst consisting essentially of Al 2 O 3 and Cl or Br is prepared by contacting Al 2 O 3 with Cl 2 and Br 2 and an organic compound or mixture of organic compounds having at least 2 carbon atoms at temperatures between 200‹ and 800‹F, the organic compound comprising at least 2 atoms of carbon, X atoms of H, Y atoms of Br and/or Cl wherein either X or Y can be zero, and wherein the mole ratio of molecular Cl 2 and/or Br 2 to organic compound is greater than X-Y if X greater than or equal 2 to Y or greater than zero if X < Y. Eta-Al 2 O 3 is specified and this may be used in conjunction with SiO 2 . Many organic chlorides are specified and tetrachloroethylene is used in the Example. |
