Ru/C催化作用下生物油在超临界乙醇中的提质
Upgrading of bio-oil in supercritical ethanol over Ru/C
摘要
Abstract
To upgrade bio-oil,two upgrading methods were employed:low temperature hydrogenation (175℃) followed by supercritical upgrading in ethanol (HS),and direct upgrading in supercritical ethanol (DS). By both methods,the physical properties (heating value,pH) of bio-oil were improved greatly. Besides,the relative content of acids,ketones,and phenols decreased significantly while that of alcohols/ethers and esters increased dramatically after upgrading. The reactions occurred in each step were tentatively discussed based on GC-MS results. Compared with the upgraded bio-oil from DS,the relative content of alcohols/ethers was higher in that from HS,while the relative content of ketones,phenols,and esters showed an opposite result. The consumption of ethanol was lower in HS. The recovery of ethanol by rotary evaporation and reutilization of the recovered ethanol not only reduced the consumption of ethanol,but also increased the relative content of esters in the upgraded bio-oil. These results indicated that bio-oil could be effectively upgraded by supercritical upgrading at relatively low ratios of ethanol to bio-oil.关键词
