Abstract
(EN)




A process for improving cold flow properties of diesel range hydrocarbons
produced from renewable feedstocks
such as plant oils and animal oils. A renewable feedstock is treated by
hydrogenating and deoxygenating to provide an effluent
comprising paraffins followed by isomerizing and selectively hydrocracking at
least a portion of the paraffins to generate a diesel
range hydrocarbon product. A portion of the diesel range hydrocarbon product
is selectively separated and recycled to the isomerization
and selective hydrocracking zone.
