  • Process for synthesising hydrocarbons in the presence of a catalyst comprising a group VIII metal supported on silica-alumina
    Publication number: 20020132865
    Abstract: A process is described for synthesizing hydrocarbons from a mixture comprising carbon monoxide and hydrogen in the presence of a catalyst comprising at least one group VIII metal supported on a silica-alumina prepared by co-precipitating and calcining at a temperature in the range from about 500° C. to about 1200° C. for at least 6 hours so that said silica-alumina has a specific surface area of less than 260 m2/g. Said catalyst is used in a fixed bed or in suspension in a liquid phase of a three-phase reactor.

  • Supported cobalt-based catalyst
    Publication number: 20010041750
    Abstract: A supported cobalt-based catalyst is described, characterized in that the carrier has an average particle diameter, measured by means of Coulter LS230, ranging from 70 to 250 &mgr;m, a surface area higher than 175 m2/g and a pore volume higher than 0.35 cm3/g, measured with the B.E.T. method. The above catalyst is particularly useful in the Fischer-Tropsch reaction.

  • Process for converting synthesis gas in the presence of a catalyst based on a group VIII metal, whereby the metal particles are dispersed in the form of aggregates
    Patent number: 6235798
    Abstract: The invention relates to a hydrocarbon synthesis process in the presence of a catalyst that comprises a substrate, at least one metal of group VIII that comprises metal particles, preferably cobalt, characterized in that the group VIII metal particles of the catalyst are deposited on the substrate in the form of aggregates.

  • Fischer-Tropsch synthesis process in the presence of a catalyst the metallic particles of which have a controlled size
    Patent number: 6214890
    Abstract: The invention relates to a synthesis process for hydrocarbons using a mixture containing carbon monoxide and hydrogen, called Fischer-Tropsch synthesis in the presence of a catalyst comprising a support, at least one group VIII metal said process being characterized in that at least 80% of the group VIII metallic particles of the catalyst have a size comprised between D−(D.0.2) and D+(D.0.2), where D represents the average size of the metallic particles. The process can be used in a fixed-bed reactor of the catalyst or in a reactor operating in liquid phase of the catalyst.
