AI Technical Summary
In existing biomass hydrothermal liquefaction methods, the low hydrocarbon content of bio-oil leads to low selectivity of target components, difficulty in separation, low calorific value, and easy deterioration, affecting the economic feasibility of the process.
By employing pulse pressure treatment during the hydrothermal liquefaction process, the reaction pressure is precisely controlled, including the first pulse pressure, the second pulse pressure, and the third pulse pressure. The third pulse pressure is ensured to be greater than the first pulse pressure, which promotes the main reaction and inhibits the side reaction, thereby generating hydrocarbon-rich bio-oil.
It increases the hydrocarbon content in bio-oil to over 87.6%, simplifies the process, reduces costs, eliminates the need for catalysts, and has wide applicability.
