Abstract
The catalytic cracking of furaldehyde, as a model compound of bio-oil, was carried over HZSM-5 zeolite catalyst under the conditions of 500 ℃ and WHSV 5.0 h-1. The effect of water content in the furaldehyde on the catalytic cracking was studied and the products was analyzed by means of GC-MS. The results show that the furaldehyde catalytic cracking products contain aldehydes, ketones, furan, indenes, benzenes, naphthalene and their derivatives. With the increase of the water content in the raw material, furaldehyde is ease to be cyclize, the contents of indenes, benzenes and naphthalene in the products increase, and the contents of aldehydes, ketones and furan decrease. According to the distribution of the furaldehyde catalytic cracking products, the catalytic reaction mechanism was speculated, which is deoxidization, decarboxylation and cyclization over HZSM-5 zeolite catalyst.关键词
