Abstract

In order to develop a high combustion heat and stable bio-oil for safer transportation. The present invention discloses a low carbon bio-oil, selected from the group consisting of a thermo-chemical oil product, a fatty acid containing bio-oil and a bio-alcohol. The invention also discloses a preparation method of preparing the low carbon bio-oil.

First claim

What is claimed is:

1. A low-carbon bio-oil selected from the group consisting of a biomass thermo-chemical oil, a fatty acid-rich bio-oil, and bio-alcohol, wherein a range of high heat combustion for the low-carbon bio-oil is 3000-7000 cal/g.

2. The low-carbon bio-oil of claim 1 , wherein the weight percentage of the fatty acid-rich bio-oil of the low-carbon bio-oil is 1-20%.

3. The low-carbon bio-oil of claim 1 , wherein the weight percentage of the bio-alcohol of the low-carbon bio-oil is 0.1-10%.

4. The low-carbon bio-oil of claim 1 , wherein the biomass thermo-chemical oil is a biomass pyrolysis oil, a carbonized tar, a liquid product after carbonization, pyrolysis or gasification.

5. The low-carbon bio-oil of claim 4 , wherein the fatty acid-rich bio-oil is a black high acid value oils, a white high acid value oil or a palm fatty acid distillate (PFAD).

6. The low-carbon bio-oil of claim 5 , wherein the weight ratio of the biomass pyrolysis oil to the black high acid value oil is 1:1.

7. The low-carbon bio-oil of claim 5 , wherein the weight ratio of the biomass pyrolysis oil to the white high acid value oil is 3:1.

8. The low-carbon bio-oil of claim 5 , wherein the weight ratio of the carbonized tar to the black high acid value oil is 3:1.

9. The low-carbon bio-oil of claim 5 , wherein the weight ratio of the carbonized tar to the white high acid value oil is 3:1.

10. The low-carbon bio-oil of claim 5 , wherein the fatty acid-rich bio-oil is obtained from a waste oil after manufacture process.

11. The low-carbon bio-oil of claim 5 , wherein the bio-alcohol is ethanol, butanol or a higher alcohol.

12. The low-carbon bio-oil of claim 11 , wherein the weight ratio of the biomass pyrolysis oil, the black high acid value oil and the bio-alcohol is 15:5:1.

13. The low-carbon bio-oil of claim 11 , wherein the weight ratio of the biomass pyrolysis oil, the white high acid value oil and the bio-alcohol is 15:5:2.

14. A method for producing a low-carbon bio-oil of claim 1 , which comprises the steps of:
a) obtaining an oil mixture selected from the group consisting of a biomass thermo-chemical oil, a fatty acid-rich bio-oil, and bio-alcohol;
b) heating the oil mixture to 40-90° C.; and
c) settling the mixture at room temperature to obtain a low-carbon bio-oil.
