摘　　要：以耐水性能良好的磺化硅胶为催化剂,在模型反应的基础上,探讨了该催化剂在生物油的催化酯化改质过程中的活性和效果。结果表明,催化剂磺化硅胶可以方便地分离和循环使用,改质后生物油的理化特性得到改善,酸值降低了80.14%,热值由14.46 MJ/kg升至31.44 MJ/kg,密度降低了23.53%,运动黏度降低了79.56%,流动性增强,为生物油的改质提供了一种有效方法。On the basis of model reaction, we served silica sulfuric acid as catalyst which had good water resistance and discussed the catalytic activity ＂Results showed that silica sulfuric acid could be and effect during catalytic esterification of bio-oil. separated and reused conveniently. Physical and chemical properties of bio-oil had been improved, acidity decreased 80.14%, caloric value increased from 14.46 MJ/kg to 31.44 MJ/kg, density decreased 23.53%, kinematic viscosity decreased 79.56%, and flow ability enhanced. This provided an effective method for bio-oil modification.
