Optimization Of Direct Conversion Of Methane To Liquid Fuels Over Cu Loaded W/ZSM-5 Catalyst

Abstract:

The optimization of methane conversion to liquid fuels over copper loaded W/ZSM-5 catalyst was studied by utilizing experimental design from ‘Statsoft Statistica’ version 6.0 software. Response surface methodology was employed to determine the optimum methane conversion and C₅⁺ selectivity. Numerical results indicated the optimum methane conversion of 29.4% with the corresponding C₅⁺ selectivity of 57.2% were achieved at 12.3 vol% of O₂, 203.9 ml/min of total feed flow rate, and %W doped of 3.2 wt%. The optimum C₅⁺ selectivity of 70.2% was attained at 7.6 vol% of O₂, 208.9 ml/min of total feed flow rate, and 3.2 wt% of W content with the corresponding methane conversion of 26.7%. By means of variance analysis and additional experiments, the adequacy of this model is confirmed.
