Improvement of methane activation using n-hexane as co-reactant over Zn/HZSM-11 zeolite

Abstract

Significance of effective conversion of methane (C1) to more valuable compounds such as aromatics is studied using n-hexane (C6) as co-reactant. AH yield was as high as 30 mol% C using the following reaction conditions: temperature, 500 C; contact time w=f ¼30 g h mol 1 and a C1 molar fraction, XC1: ¼(C1/C1 +C6)¼0.60, was achieved. The effect of the contact time, molar fraction, and time on stream was analyzed in order to obtain more information about different species evolution. The C1 conversion reached at 50 mol% C using Zn/HZSM-11 with 2.13 mol Zn per cell unit.
