用生物碳代替化石碳炼铁是减少CO2排放的有效方法之一。加拿大生物碳资源储量十分丰富,所以,相关部门正在开展生物碳炼铁工艺研究并取得了一些可喜成果。完成了用碳生命周期对生物碳炼铁工艺前景评价和技术路线的可行性研究;完成了加拿大工业规模生物质炼铁所需生物碳资源的客观形势分析以及路边林业残余生物碳的收集、 Replacing Fossil Carbon with Biochar Ironmaking is an effective way to reduce CO2 emissions. Bio-carbon resources in Canada are very rich in reserves, therefore, the relevant departments are carrying out biofuels research and made some gratifying achievements. Completed the carbon life cycle of biofuels carbon technology prospects and technical feasibility studies; completion of the Canadian industrial-scale biomass biofuels required for the analysis of the objective situation of biochar resources and roadside forestry residual biochar collection,
