36 ABSTRACT OF THE DISCLOSURE A compound oxide catalyst carrier which comprises a silica-alumina or a titania-alumina and has a relative standard deviation of peak intensity of aluminum ranging from 0.100 to 0.170, as measured by scanning a cross section of a particle of the compound oxide catalyst carrier with an EPMA in a scan-line direction along a diameter-line or an approximate diameter-line of the cross section, has a moderately uniform aluminum concentration distribution in solid particles a moderate acidity and, therefore, is suitable for use as a catalyst carrier requiring attrition resistance and ability of inhibiting generation of coke or excessive cracking, such as a carrier of catalysts for production of middle distillate fractions by a suspension bed process hydrocracking of heavy oil.
