    摘要： A hydrocracking process for converting a petroleum feedstock to higher gravity, lower sulfur products, especially ultra low sulfur road diesel fuel. The process may be operated as a single-stage or two-stage hydrocracking. In each case, a hydrocracking step is followed directly by a post-treat hydrodesulfurization zone using a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals with a ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. In the two-stage option with interstage ammonia removal, the initial hydrocracking step may be followed by hydrodesulfurization using the bulk multimetallic catalyst prior to the ammonia removal which is followed by the second hydrocracking step. A final hydrodesulfurization over the bulk multimetallic catalyst may follow. The hydrodesulfurization over the bulk multimetallic catalyst is carried out at a pressure of at least 25 barg and preferably at least 40 barg.

    摘要： A method has been developed for the solution-based metal exchange of carboxylato-alumoxanes [Al(O)x(OH)y(O2CR)z]n with a wide range of metal cations. Metal-exchanged carboxylato-alumoxanes are new, particularly those in which about 10% to about 50% or more of the Al ions are exchanged for other metal ions. Additionally, the carboxylic acid ligands can be stripped from the boehmite core of metal-exchanged carboxylato-alumoxanes at low temperature leading to the formation of metal-exchanged boebmite particles. These new material phases can be used as intermediates for preparation of mixed metal aluminum oxide materials. Thermolysis of the metal-exchanged carboxylato-alumoxanes or metal-exchanged boehmite particles results in doped aluminas (M/Al2O3), binary (MAlOx), ternary (MM′AlOx) and even more complex metal aluminum oxide compounds, where M and M′ are metal ions other than those of aluminum and are preferably those of Lanthanide metals or transition metals. The method allows preparation of pure phase materials as well as the preparation of metastable metal aluminum oxide phases. The carboxylato-alumoxanes are prepared by the reaction of boehmite (or pseudoboehmite) with carboxylic acids in a suitable solvent. Up to at least half of the aluminum cations in the boehmite lattice of the carboxylato-alumoxanes can be replaced by the reaction of metal acetylacetonates with the carboxylato-alumoxane in a suitable solvent. The metal exchange reaction can also be carried out by reaction with soluble metal salts. Reactions of boehmite with the metal acetylacetonates (or soluble metal salts) do not lead to the metal exchange reaction observed for the carboxylato-alumoxanes.
