  • Process for the production of hybrid catalysts for fischer-tropsch synthesis and hybrid catalyst produced according to said process
    Patent number: 8097555
    Abstract: 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 hydroisomerization 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 utilized 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.
    Type: Grant

  • PROCESS FOR THE PRODUCTION OF HYBRID CATALYSTS FOR FISCHER-TROPSCH SYNTHESIS AND HYBRID CATALYST PRODUCED ACCORDING TO SAID PROCESS
    Publication number: 20090143220
    Abstract: 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.
