Process for the production of hydrocarbons

摘要

A process for the production of hydrocarbons is presented capable of converting a mixture of hydrogen and carbon monoxide (synthesis gas) into hydrocarbons, employing a hybrid catalytic system with intermediate injection of hydrogen. Said process of production of hydrocarbons operates in at least one reactor under typical conditions for Fischer-Tropsch synthesis and consists of utilisation of two types of catalyst, one whereof being a catalyst of characteristic type active in Fischer-Tropsch synthesis, the other being a catalyst of bifunctional type active in hydrocracking and hydroisomerisation reactions. In one embodiment of the present catalytic process of production of hydrocarbons both types of catalyst may be physically mixed and disposed such as to form a single-phase catalytic reaction bed in said single reactor. In another embodiment of the present catalytic process of production of hydrocarbons said types of catalyst may be disposed segregated in different catalytic reaction beds in at least one reactor. In both arrangements there is formed a hybrid catalytic system which receives an intermediate injection of hydrogen.
