Experimental and Molecular Simulation Studies on Ethanol Conversion to Propylene Over Different Zeolite Catalyst
The selectivity of propylene was constant at 20% during continuous experiments for 8 h on HZSM-5. However, HLEV catalysts produced almost no C3H6 after 2 h. The rapid change is probably due to coke deposition. Excessive adsorption of ethanol on HLEV leads to coke deposition. Lower adsorption energy of ethylene on HLEV makes ethylene desorb quickly after formation. [GRAPHICS] .
