PROCESSES FOR PRODUCING A FUEL FROM A RENEWABLE FEEDSTOCK

摘要

An apparatus and a process for providing a green diesel with improved flow properties. A renewable feed comprising an oil is deoxygenated to provide an effluent. The effluent may be isomerized to improve the qualities of the effluent for use as a diesel fuel. Additionally, the effluent may be filtered to increase the fuel flow properties. As filtration zone can be used, which includes a filter and which may be flushed with a portion of the feed stream to the filtration zone or a portion of filtration zone effluent. The wash stream may be heated.

1. A process for improving a fuel flow property of bio based diesel fuel, the process comprising:
converting a biorenewable feedstock in a reaction zone having a catalyst and being operated under conditions to provide a hydrocarbon effluent; isomerizing the hydrocarbon effluent in an isomerization zone having an isomerization zone being operated at conditions to provide an isomerization effluent; filtering one or more contaminants from the isomerization effluent in a filtration zone having a filter configured to remove at least 70% of particles with an average particle size of between about 0.1 to 5 micrometers to provide a filtered effluent; and, separating at least a diesel range fuel stream from the filtered effluent.
