PROCESS FOR THE PRODUCTION OF HYBRID CATALYSTS FOR FISCHER-TROPSCH SYNTHESIS AND HYBRID CATALYST PRODUCED ACCORDING TO SAID PROCESS |
摘要 |
Process for the production of hybrid catalysts formed by mixing two catalysts; one active in Fischer-Tropsch synthesis, the other being bifunctional. Such hybrid catalyst thus formed is active both in hydrocracking and in hydroisomerisation reactions. The present invention in addition provides obtainment of a hybrid catalyst and application thereof conjointly with FT catalysts in Fischer-Tropsch synthesis reactions. The hybrid catalyst of the present invention is capable of producing in conditions typically such as those utilised in Fischer-Tropsch synthesis branched hydrocarbons in diverse bands relating to the products thereof (for example naphtha and diesel), reducing or even eliminating necessity for a subsequent hydrotreatment stage in such synthesis reactions. Utilisation of such hybrid catalysts of the present invention prolongs the operational efficiency and working life of conventional Fischer-Tropsch synthesis catalysts, reducing substantially encapsulation of particles thereof by waxes produced in the hydroprocessing reactions.
