Production of paraffinic Fuels from renewable sources by a procedure that involves a continuous hydrotreating pretreatment Stage with Hydrogen

摘要

A process, such as vegetable oil, that processes food or loads from or from renewable sources to produce paraffin hydrocarbons, including a pre-treatment by crystallization and / or precipitation and hydrogenation of goods(a) The total energy flow can be divided into several different partial flows, the number of which is equal to the reactor catalytic zone;The proportion of all kinds of partial flow injected into the continuous catalytic area is increasing to produce paraffin containing effluent. The effluent must go through a separation stage in order to separate part of the gas and part of the liquid.RDA containing paraffin hydrocarbons. At least a part of the liquid part is recovered to the first catalytic zone, so the weight ratio of the recovery to the partial flow adopted in the first catalytic zone is greater than or equal to 10.
