Problems solved by technology

The acid value is still high, and when used in internal combustion engines, there will be serious corrosion problems
In addition, because this method cannot remove or transform the sugar compounds in the organism, the problem of polymerization and coking in the esterification process cannot be fundamentally solved

Embodiment 1

[0039] Put 200 g of bio-oil in a 500 mL flask, then add 60 g of water (the mass ratio of bio-oil / water is 1:0.3) under the action of mechanical stirring, stir and extract at room temperature for half an hour, transfer to 500 mL In the liquid funnel, 179.76 g of water-soluble phase (upper layer) and 80.24 g of oil-soluble phase (lower layer) were obtained. See Table 2 for other indicators of oil-soluble phase and water-soluble phase.

Embodiment 2

[0041] Put 200 g of bio-oil in a 500 mL flask, then add 120 g of water (the mass ratio of bio-oil / water is 1:0.6) under mechanical stirring, stir and extract at room temperature for half an hour, transfer to 500 mL In the liquid funnel, 242.48 g of water-soluble phase (upper layer) and 77.52 g of oil-soluble phase (lower layer) were obtained. See Table 2 for other indicators of oil-soluble phase and water-soluble phase.

Embodiment 3

Abstract

The invention discloses a method for preparing fuel oil with a high calorific value by upgrading biological oil (high-speed thermally cracked biomass oil), and particularly relates to a method comprising the steps of firstly, adding water to divide the biological oil into a water soluble phase and an oil soluble phase, and then, upgrading the water soluble phase by using a chemical extracting-to-coupling conversion technology and upgrading the oil-soluble phase through hydrodeoxygenation. The method can be used for subjecting compounds such as acid, aldehyde and the like in the water soluble phase and fatty alcohol with 1-4 carbon atoms to esterification and acetalation to obtain ester, acetal, hemiacetal and the like with good combustibility, and the fuel oil with the high calorific valueis prepared after the oil soluble phase is subjected to hydrodeoxygenation. The method has the advantages that few cokes are generated in an upgrading process, and after being upgraded, an oil product is low in water content and acid value, high in calorific value and the like.

Description

technical field [0001] The invention relates to a method for improving the quality of bio-oil (biomass rapid pyrolysis oil) oil. Specifically, it involves first dividing the bio-oil into a water-soluble phase and an oil-soluble phase by adding water, and then using extraction coupling chemical conversion technology to make the water-soluble phase react with fatty alcohols containing 1 to 4 carbon atoms for esterification and acetalization reactions, and then extract the bio-oil into A method and device for producing high-calorific-value fuel oil by hydrodeoxygenating oil-soluble phases by converting organic acids and aldehydes with good flammability into esters, acetals, and hemiacetals. Background technique [0002] Bio-oil is a liquid product obtained by rapid heating and pyrolysis of biomass at 450-500°C under anaerobic or hypoxic conditions, and then rapid condensation. Biomass is a renewable and clean energy, and the production of bio-oil through rapid pyrolysis is exp...
