One possible way for the production of alternative fuels from renewable biomass is through catalytic oligomerization of biomass-derived light olefins such as ethylene. In this work, HZSM-5-based catalysts have been prepared and evaluated for ethylene oligomerization for liquid fuel production at 300 oC under atmospheric pressure. The production of gasoline-like fuels was confirmed by the GC-FID and Simulated Distillation GC analysis. With the modification of NaOH solution, the pore size of original HZSM-5 can be enlarged. Compared to original HZSM-5 catalyst, the modified catalyst showed higher ethylene conversion and liquid yield. In addition, the stability and the resistance to carbon deposition were also improved. Loading Ni onto HZSM-5 could promote its activity for ethylene oligomerization. However, it suffered severe carbon deposition within 5 h of reaction, reaching to 66%. The current study indicates that enlarging the pore size of HZSM-5 catalyst is a promising approach for this reaction.
