Abstract: A biocomponent feedstock can be hydroprocessed using an FCC off-gas as a hydrogen source. A relatively low cost catalyst, such as a water gas shift catalyst and/or spent hydrotreating catalyst, can be used as a hydrogenation catalyst for the process. The hydroprocessing can allow for olefin saturation and/or deoxygenation of the biocomponent feed by using a relatively low value refinery stream.

Abstract: Separated volumes can be created in a reactor using interior dividing wall or interior conduit structures. Feedstocks can be hydroprocessed in the separated volumes to allow multiple types of hydroprocessing conditions and/or feeds to be processed in a single reactor. The feedstocks can remain separate for the entire volume of the reactor, or the dividing barrier can end at some intermediate point in the reactor.

Abstract: The invention relates to a method for forming an at least partially renewable diesel product, comprising: hydrodeoxygenating a feedstock comprising about 0.1 wt % to about 50 wt % of a fresh biocomponent portion with a relatively pure hydrogen treat gas in the presence of a hydrodeoxygenation catalyst under relatively low total pressure to form a hydrodeoxygenated product; and separating the hydrodeoxygenated product into a vapor effluent and a liquid effluent, at least a first portion of the latter being recycled to the hydrodeoxygenation step, and at least a second portion of the latter being a diesel product. Advantageously, the hydrodeoxygenation catalyst can have a relatively low catalytic activity (about 50% or less of fresh HDS/HDN activity).

Abstract: Diesel fuel is produced from a feedstock that is at least partially biocomponent in origin. A feedstock is treated in a reactor including one or more hydrotreating zones having a continuous gas phase. The liquid effluent from the hydrotreating zones is then hydroprocessed in a hydroprocessing zone having a continuous liquid phase, such as a hydroprocessing zone in the same reactor. The hydroprocessing zone can be operated under effective catalytic dewaxing conditions.

Abstract: Non-hydrotreated biocomponent feeds can be mixed with mineral feeds and processed under catalytic isomerization/dewaxing conditions. The catalytic isomerization/dewaxing conditions can be selected to advantageously also substantially deoxygenate the mixed feed. Diesel fuel products with improved cold flow properties can be produced.

Abstract: Feeds containing a hydrotreated biocomponent portion, and optionally a mineral portion, can be processed under catalytic conditions for isomerization and/or dewaxing. The sulfur content of the feed for dewaxing can be selected based on the hydrogenation metal used for the catalyst. Diesel fuel products with improved cold flow properties can be produced.

Abstract: A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a ZSM-48 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.

Abstract: 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.

Abstract: A biocomponent feedstock can be hydroprocessed using a hydrogen-containing refinery as a source of hydrogen gas. A relatively low cost catalyst, such as a water gas shift catalyst and/or spent hydrotreating catalyst, can be used as a hydrogenation catalyst for the process. The hydroprocessing can allow for olefin saturation and/or deoxygenation of the biocomponent feed by using a relatively low value refinery stream, e.g., containing from about 20 mol % to about 60 mol % hydrogen.

Abstract: This invention provides processes for producing fuel, particularly transportation fuel, from biological material, e.g., lipid material. One aspect of the invention involves hydroprocessing a feedstock in a hydroprocessing zone that is maintained at conditions that promote the efficiency of converting the lipid-containing feedstock into transportation fuel. Such conditions include one or more of maintaining CO content of the hydroprocessing zone at a predetermined amount and recycling or providing a hydrogen-containing gas to the hydroprocessing zone that has been treated to remove CO.

Abstract: This invention relates to processes for the production of a fuel composition from a feedstock that comprises lipid material (e.g., bio-material) and mineral oil. The processes can be carried out without producing a significant mount of undesirable side reactions such as cracking, polymerization, and aromatization, which can be an undesirable consequence of large heats of reaction. As a result, the invention provides for the production of a product that is relatively high in quality, and catalyst used in the processes is not adversely affected to any significant extent.

Abstract: This invention relates to the production of dewaxed and/or hydroisomerized fuel composition that includes a step of hydrotreating a feedstock containing the lipidic material. The fuel compositions are high quality fuel compositions in which the fuel can be ultimately tailored for a variety of end uses such as jet fuel or diesel fuel.

Abstract: 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.

Abstract: A biocomponent feedstock can be hydroprocessed using an FCC off-gas as a hydrogen source. A relatively low cost catalyst, such as a water gas shift catalyst and/or spent hydrotreating catalyst, can be used as a hydrogenation catalyst for the process. The hydroprocessing can allow for olefin saturation and/or deoxygenation of the biocomponent feed by using a relatively low value refinery stream.

Abstract: 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.

Abstract: Processes are provided for producing a diesel fuel product having a sulfur content of 15 wppm or less (e.g., 10 wppm or less) from feed sources that include a biocomponent feedstock. The biocomponent feedstock can be initially co-processed with a mineral feed in a fluidized bed stage, such as an ebullating bed processing stage. Ebullating bed processing can mitigate the impact of the biocomponent feed on other hydrotreatment aspects of a diesel boiling range feed. Challenged biocomponent feeds can be handled by introducing the biocomponent feed into the ebullating bed reactor in a manner that reduces the fouling impact of the feed.
