Abstract
Organic compound conversion in the presence of refractory metal oxide solid materials, characterized by the presence of surface hydroxyl groups, which have undergone modification by being subjected to the sequential steps of (1) silylating, (2) calcining and (3) steaming is provided. The silylating step in the modification of the refractory materials is accomplished by contacting the solid material with an organic- or halogen-substituted silane at a temperature of between about 25.degree. C and about 500.degree. C to effect bonding between the silane and the surface hydroxyl groups of the solid. The calcining step in the modification of the refractory materials is accomplished by heating the resulting silylated solid at a temperature and for a time sufficient to remove substantially all of any introduced organic or halogen substituent. The steaming step in the modification of the refractory materials is accomplished by contacting the resulting calcined solid with an atmosphere containing at least 2 percent by volume of steam at a temperature of between about 900.degree. F and about 1600.degree. F for at least about 1/2 hour.
