Abstract:
1. A method of using a crystalline alumino silicate as a catalyst for removal of higher hydrocarbons from natural gas by simultaneous conversion of the hydrocarbons in the natural gas to aromatic compounds and methane, wherein the natural gas contains sulphur compounds, and wherein the crystalline alumino silicate has, in its anhydrous state, a formula expressed in terms of mole ratios as follows: 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 insoluble sulphide by contact with a sulphur compound being present in the natural gas and/or in a preparation mixture for preparation of the alumino silicate.
