    Abstract: 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.

    Abstract: A process and apparatus for producing biofuel from biorenewable feedstock is disclosed. The process comprises hydrotreating the biorenewable feed stream in a hydrotreating reactor to hydrodeoxygenate a biorenewable feed stream to provide a hydrotreated effluent stream. The hydrotreated effluent stream is separated in a hot separator into a hot separated vapor stream and a hot separated liquid stream. A hydroisomerization feed stream is taken from the hot separated liquid stream and hydroisomerized in a hydroisomerization reactor to provide a hydroisomerized stream. All or a portion of a return stream taken from the hot separated vapor stream is recycled to the hydroisomerization reactor. The disclosed process and apparatus minimize the carryover of the normal C16 to the biofuel and maximizes the hydroisomerization of n-paraffin hydrocarbons in the hydrotreated effluent stream to produce a biofuel which meets the biofuel specification without affecting or compromising the biofuel yield.

    Abstract: Processes for producing linear alkylbenzenes from natural oils incorporating hydrogen and heat integration are described. The processes include recycling at least a portion of the hydrogen stream to the linear selective cracking unit, and heating exchanging the paraffin stream, or the C9 to C14 stream, or the C14+ stream, or the first stream, or the second stream, or combinations thereof with the dehydrogenated stream, or the alkylation effluent stream, or both; or providing heat from deoxygenating the natural oil to the linear selective cracking unit, or the dehydrogenation unit, or the alkylation unit, or combinations thereof, or both.

    Abstract: 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.
