Patent ID: 8105397

Claim:
A process for the transformation of carbon containing compounds having a weight average carbon content of less than 30%, with a conversion yield of at least 80% by weight, into a mix of hydrocarbon compounds with 3 to 23 carbon atoms, said mix being liquid at 20° C. and at 10 5 Pa, in which the said carbon containing compounds are reacted at least partly at a temperature comprised between 100° C. and 750° C., in presence of at least one reactive material and in presence of an alumino-silicate catalytic system comprising at least one counter ion selected from the group Na, K, Ca and mixtures thereof in a sufficient amount so that a (water/alumino-silicate catalytic system) mixture prepared by mixing 0.2 g of catalyst in powder form with 20 ml water having a pH of 5.56 and a temperature of 20° C., has a pH measured at 20° C. comprised between 4 and 6, whereby the alumino-silicate catalytic system has: a BET surface comprised between 5 and 60 m 2 /g, and a surface formed by mesopores with a size comprised between 2 nm and 50 nm, comprised between 5 and 50 m 2 /g, said alumino-silicate catalytic system further comprising 0.005% to 1% by weight of at least one element selected from the group consisting of Ba, Sr and mixtures thereof with respect to the dry weight of the alumino-silicate catalytic system.
