Abstract
The present invention relates to a process for producing mixture of fuel components, which process comprises providing a feed of biological origin; subjecting said feed of biological origin and a hydrogen gas feed to a single step of hydroprocessing in the presence of a catalyst system comprising dewaxing catalyst to form a mixture of fuel components. The present invention relates also to an apparatus for producing a mixture of fuel components from a feed of biological origin. The invention relates also to the use of the fuel components.
Claims13
A process for producing a mixture of fuel components, wherein the process comprises
- providing a feed of biological origin selected from tall oil, crude tall oil, resins and resin acids obtained from plants, and bio-oil from hydropyrolyzed wood;
- subjecting said feed of biological origin and a hydrogen gas feed to a single step of hydroprocessing in the presence of a catalyst system comprising a NiW catalyst supported on zeolite-Al2O3, wherein the volume ratio of hydrogen gas feed to feed of biological origin is 100:1 to 1250:1 normal liter/liter, to form a mixture of fuel components,
- said NiW catalyst supported on zeolite-Al2O3 effecting the hydroprocessing by hydrodeoxygenating, hydrodesulfurizing, isomerizing, ring opening and cracking the feed of biological origin, and
- separating from the mixture of fuel components a fraction comprising C17 and higher hydrocarbons and recycling the fraction back to the feed of biological origin and/or to the step of hydroprocessing.
