A process for producing fuel components from a material of biological origin, comprising the following steps a) evaporating the material of biological origin for removing impurities from the material of biological origin to produce purified biological material, b) hydroprocessing said purified biological material in the presence of hydrogen gas and at least one catalyst to form a mixture of hydrocarbon compounds, c) separating gaseous compounds from said mixture of hydrocarbon compounds to obtain liquid hydrocarbon compounds, d) fractionating said liquid hydrocarbon compounds to obtain fuel components, characterized in that the material of biological origin is selected from the group consisting of fish oils such as Baltic herring oil, salmon oil, herring oil, tuna oil, anchovy oil, sardine oil, and mackerel oil; plant oils such as rapeseed oil, colza oil, canola oil, tall oil, crude tall oil, sunflower seed oil, soybean oil, corn oil, hemp oil, linen seed oil, olive oil, cottonseed oil, mustard oil, palm oil, peanut oil, castor oil, Jatropha seed oil, Pongamia pinnata seed oil, palm kernel oil, and coconut oil; and animal fats such as lard, tallow, rendered lard and rendered tallow, and waste and recycled food grade fats and oils, as well as fats, waxes and oils produced by genetic engineering; animal waxes such as bee wax, Chinese wax insect wax), shellac wax, and lanoline (wool wax); plant waxes such as carnauba palm wax, Ouricouri palm wax, jojoba seed oil, candelilla wax, esparto wax, Japan wax, rice bran oil, terpenes, terpineols and triglycerides or mixtures thereof characterized in that: the evaporating is accomplished in two evaporation steps, whereby in the first step of the evaporation water and light components are removed at a temperature of 50 - 250°C and a pressure of 5 - 100 mbar; and in the second step the fraction containing pitch is minimized by evaporating the liquid product of the first evaporation step at a temperature of 200 - 450°C and a pressure of 0 - 50 mbar; or the evaporating is accomplished in three evaporation steps, whereby in the first step, water and light components are removed at a temperature of 50 - 250°C and a pressure of 5 - 100 mbar; and in the second step the liquid product of the first evaporation step is evaporated at a temperature of 180 - 350° and a pressure of 0.1 - 40 mbar; and in the third step the fraction containing pitch is minimized by evaporating the liquid fraction of the second evaporation step at a temperature of 200 - 450°C and a pressure of 0 - 50 mbar. a) evaporating the material of biological origin for removing impurities from the material of biological origin to produce purified biological material, b) hydroprocessing said purified biological material in the presence of hydrogen gas and at least one catalyst to form a mixture of hydrocarbon compounds, c) separating gaseous compounds from said mixture of hydrocarbon compounds to obtain liquid hydrocarbon compounds, d) fractionating said liquid hydrocarbon compounds to obtain fuel components, the evaporating is accomplished in two evaporation steps, whereby in the first step of the evaporation water and light components are removed at a temperature of 50 - 250°C and a pressure of 5 - 100 mbar; and in the second step the fraction containing pitch is minimized by evaporating the liquid product of the first evaporation step at a temperature of 200 - 450°C and a pressure of 0 - 50 mbar; or the evaporating is accomplished in three evaporation steps, whereby in the first step, water and light components are removed at a temperature of 50 - 250°C and a pressure of 5 - 100 mbar; and in the second step the liquid product of the first evaporation step is evaporated at a temperature of 180 - 350° and a pressure of 0.1 - 40 mbar; and in the third step the fraction containing pitch is minimized by evaporating the liquid fraction of the second evaporation step at a temperature of 200 - 450°C and a pressure of 0 - 50 mbar.
