摘要:
C5+ hydrocarbon synthesis by contracting a synthesis gas with a catalyst naming at least one metal from group VIII deposited on a support formed by at least one oxide, said catalyst being prepared using a process of at least: i) contracting at least the support with at least one solution containing at least one precursor of metal from group VIII; ii) contracting at least the support with at least one organic compound formed from at least one cyclic oligosaccharide composed of at least 6 α-(1,4)-bonded glucopyranose subunits; iii) at least one calcining to obtain at least the metal from group VIII in the oxide form; i) and ii) being carried out separately, in any order, or simultaneously.

摘要:
A catalyst composition for the vapor phase ammoxidation of alkanes and olefins of the general empirical formulae: VSbaMbOx VSbaMbM′b′Ox VSbaMbQcOx VSbaMbQcQ′c′Ox wherein M and M′ are at least one element selected from magnesium, aluminum, zirconium, silicon, hafnium, titanium and niobium, M and M′ being different, Q and Q′ are at least one element selected from rhenium, tungsten, molybdenum, tantalum, manganese, phosphorus, cerium, tin, boron, scandium, bismuth, gallium, indium, iron, chromium, lanthanum, yttrium, zinc, cobalt, nickel, cadmium, copper, strontium, barium, calcium, silver, potassium, sodium and cesium, Q and Q′ being different, a is 0.5 to 20, b is 2 to 50, b′ is 0 to 50, c is 0 to 10, c′ is 0 to 10 and x is determined by the valence requirements of the elements present. The catalyst composition containing isolated vanadium and antimony species in an inert matrix is prepared by incorporating respective compounds of vanadium and antimony into the oxide of at least one or more M and adding by co-precipitation or impregnation one or more optional Q in the relative atomic proportions indicated by the subscripts.
