ABSTRACT:
Hydrogenation-dehydrogenation of suitable feedstock is provided wherein such feedstock is subjected to hydrogenation-dehydrogenation conditions in the presence of a catalytic amount of a solid containing, at least in part, a synthetic amorphous solid prepared by hydrolyzing and polymerizing in the presence of water a silane having the formula R(Si)X.sub.3, wherein R is a nonhydrolyzable organic group, X is a hydrolyzable group and (Si) is selected from the group consisting of ##STR1## and calcining the polymerized product, said silane being admixed with a second compound, R'.sub.n MY.sub.m, 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, IVA, VA, IVB, VB, VIB, VIIB 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.
