摘要:
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.
摘要:
A protected solid adsorbent is disclosed that includes a solid adsorbent substrate and a surface layer at least partially coating the solid adsorbent substrate, the surface layer being generally permeable to an active agent. Additionally, a process for protecting a solid adsorbent and an adsorption system that includes a vessel containing the protected solid adsorbent is provided.
