Abstract:
1. A method for isomerizing and/or dewaxing a diesel fuel, comprising: mixing a biocomponent feed portion with a mineral feed portion to form a combined feedstock, the combined feedstock having a sulfur content of less than about 500 wppm, the biocomponent feed portion being at least about 25 wt % of the combined feedstock; and contacting the combined feedstock with an isomerization/dewaxing catalyst under effective isomerization and/or dewaxing conditions including a temperature of at least about 350° C., the isomerization/dewaxing catalyst comprising ZSM-48 and at least 0.5 wt % of Pt, Pd, or a combination thereof, the ZSM-48 having a silica to alumina ratio of about 75:1 or less, the isomerization and/or dewaxing conditions being sufficient to produce an isomerized and/or dewaxed product having a cloud point of about −20° C. or less, wherein the biocomponent feed portion is hydrotreated prior to contacting the combined feedstock with the isomerization/dewaxing catalyst.
