PROCESS FOR THE REMOVAL OF HIGHER HYDROCARBONS FROM NATURAL GAS

摘要

Process for the removal of higher hydrocarbons contained in natural gas further containing sulphur compounds by simul-taneous conversion of the hydrocarbons to aromatic com-pounds and methane in presence of a catalyst comprising a crystalline alumino silicate having in its anhydrous state a formula expressed in terms of mole ratios as follows: xQ: 0.01 - 0.1 M2/n O:0-0.08 Z2O3:SiO2:0.0001 - 0.5 Me, wherein: Q is an organic nitrogen compound; Z is aluminum, boron, gallium or mixtures thereof; x is between 0 and 0.5; M is at least one metal cation of valence n or proton; and Me is at least one of the metals, which form a water in-soluble sulphide by contact with a sulphur compound being present in the natural gas and/or in a preparation mixture for preparation of the catalyst.
