Process for converting light alkanes to higher hydrocarbons
This patent describes a process for converting a lower alkane to higher hydrocarbons in stages comprising: passing a reaction mixture including the lower alkane, HCl and O/sub 2/ into contact with an oxyhydrochlorination catalyst to form an intermediate gaseous mixture included chlorinated alkanes and water; drying the intermediate gaseous mixture to less than about -40/sup 0/C dew point; passing the dried intermediate gaseous mixture into contact with a crystalline aluminosilicate catalyst at a temperature in excess of 200/sup 0/C to form a product mixture containing dry HCl and higher hydrocarbons than the alkane; separating the dry HCl from the product mixture and recycling the HCl for reaction with the lower alkane and oxygen in the presence of the oxyhydrochlorination catalyst.
