Original Abstract Submitted
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.
