AI Technical Summary

Technical Problem

In existing technologies, traditional SAF synthesis relies on fossil fuel heating, resulting in high carbon emissions, low energy efficiency, unstable hydrogen supply, and difficulty in achieving continuous and stable operation of solar-driven biomass gasification. Furthermore, waste heat recovery is insufficient, failing to meet the low-carbon and high-efficiency requirements of SAF synthesis.

Method used

Energy is provided by a solar molten salt photothermal conversion system, and steam is heated by a heat storage medium to drive a gasification reaction. The sensible heat of crude syngas is recovered to generate hydrogen for power generation. Combined with a Fischer-Tropsch synthesis reactor and catalyst, hydrogen self-sufficiency and stability are achieved, and syngas purification and separation are optimized to form a closed-loop energy utilization.

Benefits of technology

This technology enables the efficient preparation of low-carbon SAF, reduces the carbon footprint, improves energy efficiency, ensures continuous and stable system operation, enhances product yield and quality, reduces solid waste emissions, and meets the requirements of green chemistry and circular economy.

Abstract

The application discloses a method and device for synthesizing sustainable aviation fuel by solar-driven biomass gasification, which comprises the following steps: heating a heat storage medium by a solar heat collection system to provide heat energy for a gasification reaction and steam generation; feeding biomass raw materials and steam into a gasification furnace to generate a gasification reaction to obtain crude synthesis gas; recovering high-temperature sensible heat of the crude synthesis gas to generate steam and generate electricity, and using the electricity to electrolyze water to prepare first hydrogen; purifying and separating and purifying the crude synthesis gas after heat exchange and temperature reduction to obtain refined synthesis gas, and separating solid carbonaceous residues and methane to be fed into a combustor to be combusted, and heat generated by the combustion is delivered to the gasification furnace; mixing the refined synthesis gas with the first hydrogen and feeding the mixture into a first-stage Fischer-Tropsch synthesis reactor to generate a hydrocarbon mixture by Fischer-Tropsch synthesis reaction under the action of a catalyst; feeding the hydrocarbon mixture and the first hydrogen into a second-stage Fischer-Tropsch synthesis reactor to generate a second-stage Fischer-Tropsch synthesis reaction, and then obtaining sustainable aviation fuel by rectification separation.
