A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a 1-D, 10 member ring molecular sieve containing catalyst. The hydrotreated feed may be cascaded directly to the dewaxing step, or the hydrotreated feed can undergo intermediate separation. The diesel fuel resulting from processing of the biocomponent feed exhibits superior cetane values.

Hydroprocessing of biodiesel fuels and blends

Embodiments of a compact pressure swing reformer are disclosed. Certain embodiments have a construction comprising multiple rotating reformer beds, high temperature rotary valves at the bed ends, and E-seals to seal the beds to the valves. Several possible designs for introducing reactants into the beds also are disclosed. The multiple reformer beds are configured to provide for pressure equalization and 'steam push'. The compact pressure swing reformer is suitable for use in fuel cell vehicle applications.

The distillate catalytic hydrodesulfurization of hydrocarbon fuels wherein the optimum hydrogen treat gas rate to maximize desulfurization is determined and introduced into the reaction zone to maintain a controlled amount of hydrogen at the surface of the catalyst during hydrodesulfurization.

Deep hydrodesulfurization of hydrocarbon feedstreams

Bulk metallic catalysts comprised of a Group VIII metal and a Group VIB metal and methods for synthesizing bulk metallic catalysts are provided. The catalysts are prepared by a method wherein precursors of both metals are mixed and interacted with at least one organic acid, such as glyoxylic acid, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.

A two stage hydrodesulfurizing process for producing low sulfur distillates. A distillate boiling range feedstock containing in excess of about 3,000 wppm sulfur is hydrodesulfurized in a first hydrodesulfurizing stage containing one or more reaction zones in the presence of hydrogen and a hydrodesulfurizing catalyst. The liquid product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid product stream, which has a substantially lower sulfur and nitrogen content then the original feedstream is passed to a second hydrodesulfurizing stage also containing one or more reaction zones where it is reacted in the presence of hydrogen and a second hydrodesulfurizing catalyst at hydrodesulfurizing conditions. The catalyst in any one or more reaction zones is a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals.
