Patent ID: 8592638

Claim:
Process for the preparation of an aliphatic C 2 -C 14 hydrocarbon product from a natural fat or derivative thereof, the process comprising the steps of: (i) providing the natural fat or derivative thereof, (ii) deoxygenating the natural fat or derivative thereof originating from step (i) in the presence of a catalyst to yield an aliphatic C 9 -C 28 hydrocarbon, (iii) hydrocracking the aliphatic C 9 -C 28 hydrocarbon originating from step (ii) in the presence of a catalyst to yield a product comprising an aliphatic C 2 -C 14 hydrocarbon, (iv) feeding the product of step (iii) to a distillation unit to provide a biogasoline product and a biodiesel product and fractions between said biogasoline product and biodiesel product, (v) recycling (a) part of said biogasoline product and said fractions between said biogasoline product and said biodiesel product, or (b) part of said biogasoline product, said fractions between said biogasoline product, and said biodiesel product from said distillation unit to a C 2 -C 14 isomerisation unit, (vi) isomerising the recycled parts into an isomerised product, (vii) feeding said isomerised product to the distillation unit, and (viii) recovering said biogasoline product of isomerised C 2 -C 14 hydrocarbon from the distillation unit.
