Know "biomass oil"

Bio-oil is a mixture of various degradants of cellulose, hemicellulose, and lignin. Biomass mainly includes firewood forests, economic forests, timber forests, crop residues, and processing residues of agricultural and forestry products such as slag and sawdust.

As the only renewable energy source that can be directly converted into liquid fuels, biomass has attracted worldwide attention due to its advantages such as huge output, storability, and carbon recycling. The conversion of renewable biomass resources into clean, high-grade liquid fuels partially replaces petroleum. This not only frees us from excessive reliance on limited petroleum resources, but also significantly reduces pollutants and greenhouse gas emissions, improves the environment, and protects the environment. .

Biomass oil is a mixture of moisture and complex oxygen-containing organic matter, ie, a mixture of cellulose, hemicellulose, and various degradation products of lignin. Its initial market position is to replace heavy oil, diesel oil and coal tar. Biomass oil can be used as fuel for direct combustion and can be used as fuel for fuel oil boilers and industrial kilns; secondly, it can replace 0# diesel fuel as internal combustion engine fuel after refined processing; and 3 it can extract or process various chemical products such as antisepsis as chemical raw materials. Agents, food seasonings, desorption agents, organic fertilizers, hydroxyacetaldehyde, and levoglucosides.

For the industrialized production of biomass oil, taking into account raw materials and other factors, the range and scale of its distribution point should be 10 km radius, and a production plant of 10,000 tons should be set up. Currently, the oil production rate of pyrolysis technology biomass oil can reach over 50% (every 2 The oil production rate per ton of straw is ≥1 ton of biomass oil. The product of the triple cogeneration plant of the project constitutes approximately 50% biomass oil and approximately 10% of combustible gas (which can be used in conjunction with the generator set for own use), approximately 20% of which Solid fertilizer (potassium fertilizer) is a science and technology environment-friendly project that can produce economic benefits in all directions.

The key technology component of biomass oil is rapid pyrolysis. This technical theory was proposed in the late 1970s. It quickly heated crushed crop stalks to more than 500 degrees, which promoted the pyrolytic cracking of macromolecules into small molecules. The oil leaves the vapor and quickly condenses to produce biomass oil.
