Abstract

The invention discloses a system for preparing hydrogen and biochar from biomass based on a steel slag extract. The system comprises a pretreatment system, a heat treatment system in which mixed reactants fully react, a solid collection system used for collecting solid residues obtained after the reaction in the heat treatment system, and a gas collection system used for collecting gas obtained after the reaction in the heat treatment system. According to the method, a calcium-magnesium alkaline reagent in the steel slag extract is used as one of reactants and can absorb moisture in the biomass raw material, so that the damage to the biomass structure and the hydrogen production reaction are facilitated, and the pretreatment of the biomass raw material is simplified. An iron-based catalystextracted from the stainless steel slag is used as a byproduct and is low in price, and batch production can be achieved. The solid residues obtained after biomass hydrogen production are mixed in sintering raw materials for iron making for use, and meanwhile biochar, calcium magnesium carbonate and an iron-based catalyst in the solid residues can be fully recycled.

Description

technical field [0001] This application relates to a system derived from carbon dioxide adsorption, utilization and sequestration (Carbon Capture, Utilization and Sequestration) based on iron and steel slag extract for biomass production of hydrogen and biochar. Background technique [0002] The existing global energy structure is still dominated by fossil fuels, but the existing energy structure based on fossil fuels will bring a lot of carbon emissions and potential climate change problems. As a carbon-free energy source, hydrogen energy has good application prospects, but the current economical and practical industrial production method is still to separate hydrogen from fossil fuels. emission problem. [0003] In this context, the iron and steel industry, as a major carbon emitter, has also proposed carbon-free ironmaking, that is, using hydrogen as an alternative reducing gas. The current main source of hydrogen is water electrolysis using new energy sources (wind powe...
