TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The hydrodeoxygenation catalyst is a water gas shift catalyst that comprises an oxide of iron, copper, zinc and/or chromium (preferably Fe3O4). The hydrodeoxygenation catalyst comprises a spent hydrotreating catalyst; and at least one metal from Group VIB of the periodic table of elements and at least one metal from Group VIII of the periodic table of elements. The spent hydrotreating catalyst comprises nickel and/or cobalt and comprises molybdenum and/or tungsten. The vapor effluent is used as a refinery fuel gas. The hydroisomerization catalyst comprises a molecular sieve having a SiO2:Al2O3 ratio of less than or equal to 100 and a metal oxide binder, and the dewaxing catalyst has a ratio of zeolite surface area to external surface area of at least 80:100. The molecular sieve is EU-1, zeolite beta, ZSM-35, ZSM-11, ZSM-57, NU-87, ZSM-22, EU-2, EU-11, ZBM-30, ZSM-48 and/or ZSM-23. The metal oxide binder in powder form has a surface area of less than or equal to 100 m2/g. The metal oxide binder comprises at least one of silica, alumina, titania or zirconia. The hydroisomerization catalyst also comprises a promoter metal selected from the metals of Group VIII of the periodic table of elements. The hydrotreated mineral hydrocarbon stream is in a diesel and/or higher temperature boiling range. The feedstock comprises a mineral hydrocarbon component (at least 5 wt.%) having a sulfur content of less than or equal to 100 wppm and a nitrogen content of less than or equal to 50 wppm. The mineral hydrocarbon component comprises kerosene boiling range stream.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method further involves hydroisomerizing the first portion of the liquid effluent prior to recycle; and mixing the hydrodeoxygenated product with a hydrotreated mineral hydrocarbon stream having sulfur content of less than or equal to 30 wppm and a nitrogen content of less than or equal to 30 wppm. In the method, the feedstock has not previously been catalytically hydrotreated. EXAMPLE - No suitable example given.
