Description

Technical field [0001] The invention relates to a solar energy indirect thermochemical conversion system and method, in particular to a system and method for utilizing solar energy to indirectly thermochemically convert biomass slurry. Background technique [0002] Biomass is a general term for all non-fossil organic biological substances that contain inherent chemical energy. It is a renewable, naturally available, energy-rich, low-polluting material (smaller sulfur and nitrogen), which can relieve energy to a certain extent. Crisis of carbon-containing energy. Biomass can be converted into biofuels through thermochemical conversion. Such biomass includes microalgae, cellulose, food waste, etc. [0003] Microalgae is a type of single-celled algae that can achieve autotrophic energy by light. It uses photosynthesis to convert carbon dioxide into organic matter such as protein, oil, and sugar. These organic substances can be converted into biofuels, such as biodiesel, bioethanol,...
