摘要:
Processes are provided for deoxygenation of a biocomponent feedstock with reduced hydrogen consumption. The biocomponent feedstock can be processed under relatively low hydrogen partial pressures and at a relatively low treat gas ratio compared to the hydrogen need of the feedstock. The relatively low pressure, relatively low treat gas ratio hydroprocessing can result in reduced production of water and carbon monoxide and in increased production of carbon dioxide compared to relatively higher pressure process conditions.
摘要:
Processes are provided for producing a diesel fuel product having a sulfur content of 10 ppm by weight or less from feed sources that include up to 50% by weight of a biocomponent feedstock. The biocomponent feedstock is co-processed with a heavy oil feed in a severe hydrotreating stage. The product from the severe hydrotreatment stage is fractionated to separate out a diesel boiling range fraction, which is then separately hydrotreated.

摘要:
Methods are provided for hydrotreating high nitrogen feeds with improved results for nitrogen removal, aromatic saturation, and/or sulfur removal. The method includes hydrotreating the feed with a supported hydrotreating catalyst followed by a bulk metal catalyst, the hydrotreated effluent of which can be suitable for use as a feed to an FCC reactor.
摘要:
A process for preparing fuels, such as diesel fuels or jet fuels, by hydrotreating vegetable oils or fatty acid derivatives that may be applied to existing equipment for treating fossil fuels. The process comprises feeding hydrotreating a combined oxygenate feed stream, such as FAME, and a hydrocarbon feed stream until not more than 86 wt % of the esters in the oxygenate feed stream are converted to hydrocarbons, and optionally further hydrotreating the product stream within at least a second hydrotreatment reaction zone until at least 90 wt % of the esters in the oxygenate feed stream are converted to hydrocarbons, before removing and separating a hydrocarbon stream suitable for use as fuel.
