Title:
METHOD FOR PREPARING FUEL FROM LIGHT BIO-OIL
Document Type and Number:
WIPO Patent Application WO/2022/156342
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for preparing fuel from light bio-oil, characterized in comprising the following steps: step 1, converting light bio-oil into an alcohol substance; and step 2: converting the obtained alcohol substance into an ether substance. In step 2, the method for converting the obtained alcohol substance into an ether substance comprises: adding a liquid olefin containing a double bond into the obtained alcohol substance, and generating a high-quality ether substance by means of an addition reaction. In the present invention, a high-quality ether substance is generated from bio-oil by means of an addition reaction and is used as an oxygen-containing additive. According to the present method, the molecular weight of each component in light bio-oil can be increased, so as to improve the combustion performance of the light bio-oil, thereby enhancing the utilization value of the light bio-oil. Moreover, the problem of low efficiency and poor product selectivity caused by direct catalytic upgrading due to complex components in the light bio-oil can be well solved.
