Abstract

Abstract Hydrofining of suitable sulfur and/or nitrogen containing organic feedstock is provided wherein such feedstock is subjected to hydrofining conditions in the presence of a catalytic amount of a solid containing, a synthetic amorphous solid prepared by hydrolyzing and polymerizing in the presence of water a silane having the formula R(Si)X3, wherein R is a nonhydrolyzable organic group, X is a hydrolyzable group and (Si) is selected from the group consisting of -Si- and -Si(R)2-O -Si-, and calcining the polymerized product, said silane being admixed with a second compound, R'nMYm, wherein R' is selected from the group consisting of the same groups as R, Y is selected from the group consisting of the same groups as X and oxygen, M is at least one member selected from the group consisting of the elements of Groups IIIA, VIB, and VIII of the Periodic Table, m is any number greater than 0 and up to 8 and n is from 0 to any number less than 8.
