CharTech company is interested in producing biocarbon using agriculture and forest biomass residues as**feedstock to replace coal in steel making as a GHG carbon neutral source. However, biocarbon needs to have a**high carbon content and contain only low amounts of unwanted minor components, such as alkali metals and**phosphorous, in order to meet the requirements by the steel industry. In this project, CharTech is partnering with**the university group to investigate the efficacy of applying environmental friendly supercritical CO2 extraction**technology as a pretreatment for removal of the unwanted minor components from biocarbon produced from**agriculture and forest biomass residues. Supercritical CO2 is a clean and environmental-friendly extraction**process that utilizes supercritical CO2s unique liquid-like solubility and gas-like permeability properties. Applying**environmentally friendly supercritical CO2 extraction as a pretreatment for biomass residues is highly innovative.**Successful development of this novel treatment technology will allow the industry partner to take advantage of a**very large potential clean technology market by supplying biocarbon to steel makers. The project will also train**HQPs in leading edge extraction, thermodynamic modelling, and advanced characterization technologies that will**help them become key contributors in the emerging bioeconomy.

CharTech公司有兴趣利用农业和森林生物质残渣作为原料来生产生物碳，以取代炼钢中的煤炭作为温室气体碳中性来源。然而，生物碳需要有**高的碳含量，并且只含有少量不需要的次要成分，如碱金属和**磷，以满足钢铁行业的要求。在这个项目中，CharTech正在与**大学团体合作，研究应用环境友好型超临界二氧化碳萃取**技术作为从**农业和森林生物质残渣生产的生物碳中去除不需要的次要成分的预处理的有效性。超临界二氧化碳是一种清洁、环保的萃取过程，它利用了超临界二氧化碳独特的类液体溶解性和类气体渗透性。应用**环保的超临界二氧化碳萃取作为生物质残渣的预处理具有很高的创新性。**这种新型处理技术的成功开发将使行业合作伙伴能够通过向钢铁制造商提供生物碳来利用**非常大的潜在清洁技术市场。该项目还将在前沿提取、热力学建模和先进的表征技术方面培训**HQP，这些技术将**帮助他们成为新兴生物经济的关键贡献者。
