A process for upgrading a hydrocarbonaceous feedstock employing an alumina-based catalyst at least a portion of which is in the alpha phase. The catalyst has at least 25% of its pore volume in pores from 300-1,000 Åin diameter, has no more than 10% macropores, and has a surface area of less that 100
