    Abstract: 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.

    Abstract: A method of increasing the yield of renewable aviation fuel is described. A renewable feedstock rich in fatty acids having between 8 and 14 carbon atoms is selected, and the selected feedstock is hydrogenated and deoxygenated in a first reaction zone to provide an effluent rich in normal paraffins having between 9 and 15 carbon atoms. The normal paraffins are isomerized in a second reaction zone to isomerize at least a portion of the normal paraffins. The isomerization reaction mixture may be separated into a product stream comprising a product rich in branched paraffins having between 9 and 15 carbon atoms, which has a higher yield than a product stream made using a renewable feedstock rich in fatty acids having more than 15 carbon atoms.
