摘要： A three stage hydroprocessing process includes two liquid and one vapor reaction stages, both of which produce an effluent comprising liquid and vapor. Both vapor effluents comprise vaporized hydrocarbonaceous material. Fresh hydrogen is used for the hydroprocessing in both liquid stages. The second stage liquid effluent comprises the product liquid. The first stage liquid effluent is the feed for the second stage. The first stage vapor effluent is hydroprocessed in the vapor stage and then cooled to condense and recover at least a portion of the processed vapor as additional product liquid.

摘要： Disclosed is a catalytic cracking process that includes more than one catalytic cracking reaction step. The process integrates catalytic cracking steps with hydroprocessing in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, one hydroprocessing step is included between the cat cracking reaction steps, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step.

摘要： A distillate fuel feed is hydrotreated to remove heteroatoms and then separated into light and heavy hydrotreated fractions, with the heavy fraction catalytically dewaxed to improve low temperature properties. The hydrotreating and dewaxing are conducted in separate stages, which may be in the same reactor vessel. Fresh hydrogen may be passed into the dewaxing stage, with the dewaxing stage gaseous effluent then passed into the hydrotreating stage to provide hydrogen for the hydrotreating. Existing hydrotreating reaction vessels and facilities may be retrofitted to add one or more dewaxing stages.

摘要： A hydroprocessing process includes two hydroprocessing reaction stages, both of which produce a liquid and a vapor effluent, and a liquid-vapor contacting stage. The first stage vapor effluent contains impurities, such as heteroatom compounds, which are removed from the vapor by contact with processed liquid effluent derived from one or both reaction stages and, optionally, also liquid recovered from processed vapor. The first and contact stage liquid effluents are passed into the second stage to finish the hydoprocessing. The contact and second stage vapor effluents are cooled to recover additional hydroprocessed product liquid.

摘要： Hydrocarbonaceous feedstocks admixed with a flow-through catalyst and hydrogen are hydroprocessed in a hydroprocessing reactor containing a captive hydroprocessing catalyst. The flow-through catalyst is continually withdrawn with the hydroprocessed feed from the hydroprocessing reactor. The flow-through catalyst may be an FCC, hydrocracking, isomerization or ring-opening catalyst. In a preferred embodiment, the captive hydroprocessing catalyst contains Co, Ni and/or Mo on an alumina base and the flow-through catalyst is an FCC zeolitic catalyst which is withdrawn with the hydroprocessed feed from the hydroprocessing reactor and then sent to an FCC unit.
