NOVELTY - Preparing (P1) renewable hydrocarbons, involves: (a) dehydrating at least one renewable 4C alcohols, thereby forming a product comprising at least one 4C olefins; (b) oligomerizing at least a portion of at least one 4C olefins of step (a), thereby forming a product comprising at least 8-24C unsaturated oligomers; and (c) hydrogenating at least a portion of the product of step (b) in the presence of hydrogen, thereby forming a product comprising at least one 8-24C saturated alkanes.    USE - For preparing (P1) renewable hydrocarbons; for preparing renewable gasoline, renewable diesel fuel, renewable jet fuel and renewable aviation gasoline; and for preparing biofuel or biofuel precursor for forming biofuel (claimed).    ADVANTAGE - The processes provide improved, renewable biofuels with costs and performance properties comparable to, or superior to existing biofuels and petroleum-derived fuels (e.g. jet fuels). The process provides an integrated and simple methods for producing saturated 8-24C aliphatic hydrocarbons and aromatics from renewable alcohols (with low levels of olefins) derived from biomass. The process provides an on-specification fuel (e.g. gasoline, diesel, or jet fuel) which is completely comprised of renewable hydrocarbons.    DETAILED DESCRIPTION - Preparing (P1) renewable hydrocarbons, involves: (a) dehydrating at least one renewable 4C alcohols, thereby forming a product comprising at least one 4C olefins; (b) oligomerizing at least a portion of at least one 4C olefins of step (a), thereby forming a product comprising at least 8-24C unsaturated oligomers; and (c) hydrogenating at least a portion of the product of step (b) in the presence of hydrogen, thereby forming a product comprising at least one 8-24C saturated alkanes; by which the product of step (c) itself meets the requirements of at least one of ASTM D4814, ASTM D975, ASTM D910, or ASTM D1655, or a blend of at least 10% of the product of step (c) with a mixture of hydrocarbons meets the requirements of at least one of ASTM D4814, ASTM D975, ASTM D910 or ASTM D1655. INDEPENDENT CLAIMS are included for the following: (1) preparing a renewable gasoline involving: the process (P1), by which the product of step (c) itself meets the requirements of ASTM D4814, or a blend of at least 10% of the product of step (c) with a mixture of hydrocarbons meets the requirements of ASTM D4814; (2) preparing a renewable diesel fuel involving: the process (P1), by which the product of step (c) itself meets the requirements of ASTM D975, or a blend of at least 10% of the product of step (c) with a mixture of hydrocarbons meets the requirements of ASTM D975; (3) preparing a renewable jet fuel involving: the process (P1), by which the product of step (c) itself meets the requirements of ASTM D1655, or a blend of at least 10% of the product of step (c) with a mixture of hydrocarbons meets the requirements of ASTM D1655; (4) preparing a renewable aviation gasoline involving: the process (P1), by which the product of step (c) itself meets the requirements of ASTM D910, or a blend of at least 10% of the product of step c) with a mixture of hydrocarbons meets the requirements of ASTM D910; (5) a biofuel or biofuel precursor, prepared by the process (P1); and (6) a biofuel meeting the requirements of ASTM D4814, ASTM D975, ASTM D910, or ASTM D1655, prepared by blending the biofuel or biofuel precursor with a petroleum-derived hydrocarbon.
