TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The combined feedstock has a sulfur content of less than or equal to 50 wppm and a nitrogen content of less than or equal to 20 wppm. The hydrotreated feedstock has a sulfur content of 100-500 wppm sulfur. The second feedstock comprises a mineral feedstock portion that is hydrotreated under effective hydrotreating conditions prior to mixing with the biocomponent feed. The isomerized and/or dewaxed product is hydrofinished under effective hydrofinishing conditions. The molecular sieve is ZSM-23 or ZSM-48 with silica to alumina ratio of less than or equal to 90:1. The dewaxing catalyst comprises at least Ni (2 wt.%) and W and/or Mo (at least 10 wt.%). Preferred Method: The effective catalytic isomerization/dewaxing conditions include a total pressure of 400 psig (2.8 MPag) to 1500 psig (10.3 MPag), liquid hourly space velocity (LHSV) of 0.5-5 hr-1, and a treat gas rate of 500 scf/bbl (84 Nm3/m3) to 2000 scf/bbl (340 Nm3/m3). The mineral feed portion is hydrotreated by contacting with a hydrotreating catalyst including at least one hydrogenation metal under effective hydrotreating conditions prior to mixing with the biocomponent feed portion. The effective hydrotreating conditions include a temperature of 315-425 degrees C, a total pressure of 300 psig (2.1 MPag) to 3000 psig (21 MPag), LHSV of 0.2 hour-1 to 10 hour-1, and a hydrogen treat gas rate of 500 scf/bbl (84 Nm3/m3) to 10000 scf/bbl (1700 Nm3/m3). The hydrotreated feedstream is cascaded to the isomerization/dewaxing step without intermediate separation. The mineral feed portion is mixed with the biocomponent feed portion prior to hydrotreatment of the biocomponent feed portion. The isomerized and/or dewaxed product is hydrofinished under effective hydrofinishing conditions. The hydrotreating the feedstock produces a hydrotreated feedstock and a gas phase effluent containing H2S. The contacting the hydrotreated feedstock with the isomerization/dewaxing catalyst further involves: contacting at least a portion of the gas phase effluent with the isomerization/dewaxing catalyst. The method (M2) further involves: combining the hydrotreated feedstock with a second feedstock prior to the contacting with the isomerization/dewaxing catalyst, where the combined feedstock having sulfur content of 100-500 wppm sulfur. The effective hydrotreating conditions include exposing the feed to a catalyst including at least one hydrogenation metal at a temperature of 315-425 degrees C, a total pressure of 300 psig (2.1 MPag) to 3000 psig (21 MPag), an LHSV of 0.2-10 hour-1, and a hydrogen treat gas rate of 500 scf/bbl (84 Nm3/m3) to 10000 scf/bbl (1700 Nm3/m3).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The biocomponent feed portion includes a fat and/or oil whose source is at least one of vegetable, animal, fish, and algae.
