Experimental research on catalytic hydrogenation and esterification of light fraction of bio-oil
Journal Title: Science Paper Online - Year 2010, Vol 5, Issue 3
Abstract
Distilled bio-oil with a certain mount of glycerol could divide bio-oil into two groups (light fraction and heavy fraction). Due to the different character of the two groups, it is a reasonable way to upgrading them respectively. In this paper, the effect of different reducing mediums on light fraction of bio-oil had been investigated under 180 ℃ using Pd/HZSM as catalyst. The light fraction of bio-oil contained acids, aldehydes, ketones, unsaturated alcohols and some phenols. The results showed that most organic acids were transformed into esters and furfurals were eliminated. Formic acid and sodium formate could function as effective reducing medium by supplying H2 through water-gas shift reaction.
