Abstract:
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.
Abstract:
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.
Abstract:
Hydrocarbon feedstocks are hydroprocessed in reaction systems including at least one catalyst stage containing bulk metallic catalysts comprised of a Group VIII metal, a Group VIB metal, and an organic compound-based component. 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, heated, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurizaton and hydrodenitrogenation, of hydrocarbon feedstocks.
Abstract:
Bulk catalysts comprised of a Group VIII metal and a Group VI metals are prepared using commercial scale processes. The catalysts are prepared by a method wherein Group VI and Group VIII metal reagents are mixed and interacted with at least one organic complexing agent, dried, calcined, and sulfided. The catalysts are used for hydroprocessing, particularly hydrodesulfurizaton and hydrodenitrogenation, of hydrocarbon feedstocks.
Abstract:
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.

Abstract:
Processes for producing diesel fuel having sulfur content of 10 ppm by weight or less from feed sources including up to 20% by weight of a biocomponent feedstock. The process includes hydrotreating the feed sources in a first reaction zone under hydrotreating conditions, separating the first hydrotreated stream effluent from gas components and hydrotreating the first hydrotreated stream effluent in a second reaction zone under hydrotreating conditions. The mineral hydrocarbon of the feed sources can be distillate or heavier feed sources.
