摘要:
The present invention is an adsorbent for removing sulfur from hydrocarbon streams. The adsorbent includes nickel particles distributed in a phase containing silica and alumina.
摘要:
Supported metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic additive, and methods for synthesizing supported 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 additive, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurization and hydrodenitrogenation, of hydrocarbon feedstocks.
摘要:
Bulk bi-metallic catalysts for use in the hydroprocessing of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor containing an organic agent.
摘要:
Novel bulk tri-metallic catalysts for use in the hydroprocessing of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor containing an organic agent.

摘要:
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.
摘要:
A slurry hydroprocessing process for upgrading a hydrocarbon feedstock containing nitrogen and sulfur using bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals wherein the ratio of Group VIB metal to Group VIII metal is about 10:1 to about 1:10.
摘要:
Sulfur content of distillate feedstock, which is greater than 3,000 wppm, is reduced using multi-stage hydrodesulfurization by reacting the feestream in stages with reaction zone(s) containing bulk multimetallic catalyst comprised of Group VIII non-noble metal(s) and at least two group VIB metals. The ratio of Group VIB to Group VIII non-noble metals is 10:1 to 1:10.
