摘要
A catalyst support is made with a bidisperse micropore size distribution. One region has small micropores with an average pore diameter of less than 100 Angstroms units. The other region has large micropores with an average pore diameter which is between 100 and 600 Angstrom units. By adding catalytic metals for desulfurization and demetallation, a hydrotreating catalyst is made which is able to treat heavy feeds containing large metal bearing molecules. In a preferred embodiment the desulfurization metals are placed in the small micropores and the demetallation metals are placed in the larger micropores.
