生物质热裂解技术现状及碳封存潜力分析

Research Progress on Biomass Pyrolysis Technology and CO_2 Capture Capacity Evaluation

概述了生物质热裂解技术的研究现状,重点介绍了热解反应器类型、特点、工业化生产装置及产业现状,分析了生物质热裂解产物生物碳作为土壤修复剂混入土壤封存二氧化碳的可行性和潜力,生物碳直接混入土壤进行土壤修复,不仅可实现二氧化碳长期封存,而且可促进农作物增产,间接提高了捕获二氧化碳的能力。生物质热裂解可在Gt规模上捕获固存二氧化碳,大幅度提高封存二氧化碳的能力还需开发边际性土地和荒地。

The progress on biomass pyrolysis technology was reviewed. The pyrolysis reactor, pyrolysis performance,industry scale units and commercial development were introduced in detail. The feasibility of biomass pyrolysis bio- char as fertilizers for soil amendment and carbon sequestration was discussed. Biomass pyrolysis bio-char as soil fertilizer can realize the carbon sequestration for thousands of years. It also promoted the crops production and increased the CO2 capture capacity. Biomass pyrolysis technology can realize the Gt- scale capacity of CO2 sequestration. The uncultivated land should be explored in order to increase the capacity of CO2 sequestration with large scale.
