Title
Lanthanum–phosphorous modified HZSM-5 catalysts in dehydration of ethanol to ethylene: A comparative analysis
Abstract

The catalytic dehydration of ethanol into ethylene was studied over HZSM-5, phosphorous modified HZSM-5 and lanthanum–phosphorous modified HZSM-5 in the low temperature range from 473 K to 573 K. The experimental results demonstrated the lanthanum–phosphorous modified HZSM-5 offered the outstanding catalytic performance and the enhanced anti-coking ability markedly, especially for 0.5%La-2%PHZSM-5. Characterizations revealed that the improved catalytic performance and the excellent anti-coking ability of lanthanum–phosphorous modified HZSM-5 could be attributed to the harmonious acid sites and pore structure by the modification with lanthanum and phosphorous.
