NaA分子筛膜渗透蒸发制备高纯糠醛
Preparation of High-Pure Furfural Through Pervaporation on NaA Zeolite Membranes
摘要
Abstract
Continuous and compact NaA zeolite membranes were synthesized by a hot dip-coating seeding method and applied to the preparation of high pure furfural by dehydration.The effects of feeding flowrate,feedstock temperature and furfural content in the feedstock on the dehydration of furfural were investigated.The results indicated that under the conditions of feedstock temperature 80 ℃,pressure of the penetrating side less than 100 Pa,feeding flowrate 196 mL/min and furfural content in the feedstock 93.7％(w),the separation factor of the NaA membranes could reach 34 110.Under the conditions of feedstock temperature 90 ℃ and separation factor 12 000,the flux could reach 1.79 kg/(m2 · h).The furfural content in the products was 99.5％(w) and the average penetration flux on the membranes was 0.60 kg/(m2 · h) when the furfural content in the feedstock was 89.6％(w) and after continuous pervaporation was carried out for 96 h.关键词
