摘要： The process produces a diesel stream from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The recycle gas is recycled to the hydrotreating reactor without removing hydrogen sulfide, which is needed in the biorenewable feed to keep the hydrotreating catalyst active. A purification unit can be utilized on a purge gas stream to purify the gas and improve hydrogen concentration in the recycle gas when added to the recycle gas.

摘要： The process produces a diesel from a biorenewable feedstock by hydrotreating to remove heteroatoms and saturate olefins. The biorenewable feedstock is contacted in a guard bed reactor in the presence of hydrogen to saturate olefins and remove metals to produce a contacted feed stream. The contacted feed stream is then heated in a charge heater to a higher temperature than in the guard bed reactor and hydrotreated in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to deoxygenate the contacted feed stream to provide a hydrotreated stream.

摘要： A process for hydrotreating a feed stream comprising a biorenewable feedstock is disclosed. The process comprises hydrotreating the feed stream in the presence of a hydrotreating hydrogen stream and a hydrotreating catalyst to provide a hydrotreated stream. The hydrotreated stream is separated into a hydrotreated liquid stream and a hydrotreated gas stream. The hydrotreated liquid stream is subjected to stripping to provide a stripper off-gas stream. At least a portion of the stripper off-gas stream is contacted with a caustic stream to provide a sulfur-lean gas stream and a sulfur-rich caustic stream. The sulfur-rich caustic stream is further treated to provide a treated gas stream.

摘要： A bio-renewable conversion process for making fuel from bio-renewable feedstocks is combined with a hydrogen production process that includes recovery of CO2. The integrated process uses a purge gas stream comprising hydrogen from the bio-renewable hydrocarbon production process in the hydrogen production process.

摘要： A process isolates a liquid hydrocracked stream from a liquid hydroisomerized stream, so heat in the hydrocracked stream can be preserved. Preserving heat in the hydrocracked stream avoids having to reheat the hydrocracked stream before product fractionation. Particularly, kerosene in the hydrocracked stream is not cooled with the hydroisomerized stream and then reheated in fractionation to distill the kerosene range hydrocarbons from the diesel range hydrocarbons.

摘要： The invention provides processes for the production of hydrocarbons from a biorenewable feedstock blended with a mineral feedstock comprises hydrotreating to remove heteroatoms and saturate olefins. The carbon monoxide is not fed to the downstream hydroisomerization reactor but supplanted with a hydrogen gas with a low concentration of carbon monoxide so as not to poison the hydroisomerization catalyst to improve the cold flow properties for a diesel fuel.
