摘要： The invention concerns the use of a catalyst comprising at least one zeolite having a mazzite type structure in its acid form, the catalytic properties of the catalyst having been modified by depositing, on the external surface of the crystals, at least one metal selected from metals from group IIa of the periodic classification of the elements, such as Be, Mg, Ca, Sr or Ba, group IVb, such as Ti, Zr or Hf, group IIb such as Zn, Cd or Hg and group IVa such as Ge, Sn or Pb, said catalyst also comprising at least one matrix and, optionally at least one element selected from the group formed by IB and VIII of the periodic classification of the elements, for the dismutation of alkylaromatic hydrocarbons, preferably for the dismutation of toluene to produce benzene and xylenes, and/or for the transalkylation of alkylaromatic hydrocarbons, preferably for the transalkylation of toluene and trimethylbenzenes to produce xylenes.

摘要： The invention concerns a method of producing liquid hydrocarbons from natural gas, characterized in that:a) the natural gas is separated in (2) into at least two fractions, a first fraction of gas enriched with methane and a second fraction enriched with C2+ alkanesb) the methane is selectively oxidised in (7a) by molecular oxygen in the presence of a catalyst for oxidizing linkage of methanec) the fraction enriched with C2+ alkanes is at least partly mixed with the effluent from selective oxidation, when at least 80% of the molecular oxygen introduced at stage (b) has already been consumed at stage (b)d) the mixture resulting from stage (c) is pyrolysed in (7b)e) when the temperature of the mixture from stage (d) has been brought to a temperature from 300.degree. to 750.degree. C. and more particularly from 420.degree. to 550.degree. C., at least part of the olefins is converted to aromatics in (11c), in the presence of a special catalyst containing a zeolite, gallium, one or more Group VIII metals and/or rhenium, one or more additional metals selected from tin, lead, indium, germanium and thallium, possibly an alkali metal or alkaline earth metal and possibly a matrix.
