SBA-15的改性及催化文冠果油制备生物柴油
Preparation of bildiesel from sorbifolia oil catalyzed by modified SBA-15
摘要
Abstract
The supported solid base catalysts KNO3-AlSBA-15 and KNO3-Al-SBA-15, was prepated with mesoporous molecular sieve SBA-15 as carrier, and was loaded with Al and with alkali metal salts KNO3 by direct synthesis and post synthesis respectively. The catalysts were characterized by means of XRD, BET, SEM and CO2-TPD. The result showed that addition of Al had a good protection on the pore structure of catalyst. The alkalinity of catalyst was enhanced significantly after loading KNO3.The transesterification reaction process of sorbifolia oil with the catalyst for biodiesel preparation indicated that KNO3-Al-SBA-15 showed better catalytic activity than traditional catalysts. The biodiesel yield could reach 92%, and this catalyst also showed steady catalytic activity after being reused for many times.关键词
