Abstract
This invention relates to a catalyst and process for selectively hydrodesulfurizing naphtha feedstreams using a catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material.
Claims22
A selective hydrodesulfurization catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material and bound with a silica binder derived from silicone resin.
The catalyst of claim wherein the catalyst has been sulfided.
A selective hydrodesulfurization catalyst comprising at least one hydrodesulfurizing metal supported on a low acidity, ordered mesoporous support material, the selective hydrodesulfurization catalyst being made by a process comprising:
- (a) combining the low acidity, ordered mesoporous support material with silicone resin to form a mixture of mesoporous support material and silicone resin,
- (b) calcining the mixture from step (a) to convert silicone resin to silica binder,
- (c) impregnating the calcined low acidity, ordered mesoporous support material from step (b) with an aqueous precursor containing at least one metal to form a metal-impregnated, low acidity, ordered mesoporous support material;
- and
- (d) heating the calcined metal-impregnated, low acidity, ordered, mesoporous support material from step (c) at a drying temperature and drying pressure and for a drying time to remove water.
