摘要
“热”诱发、“热”驱动的热化学反应是人类最早认识的化学反应,占据工业化学反应的绝大部分,是能源转化、资源加工、循环经济等的重要反应,涉及发电、供热、冶金、建材、废物消纳等重大工业行业,这些行业是与人类活动相关的CO_(2)排放源的主体,在总碳排放中占比90%以上。在“双碳”目标下,热化学反应科学和技术的创新发展凸显更加特殊和重要的作用,其重要内容之一就是“支撑热化学反应工程化”的科学与技术,即“热化学反应工程”。针对“热”诱导、“热”驱动的化学反应,本文深入归纳和分析其相关科学和技术从古至今的发展特点,凝练形成了五个具有不同科学与技术特点的典型发展时期。总结典型热化学反应相关行业的重要科学与技术的发展及其对社会进步的贡献和影响,阐明“双碳”战略背景下“热化学反应工程”的科技创新机遇和贡献“碳中和”的潜力,揭示了通过碳减排、碳替代和碳循环的技术创新和应用推广,可有效推动我国各种“超级碳排放源”的碳排放强度和碳排放量的大幅降低,实现年60亿吨级二氧化碳的消减。
Most industrial chemical processes involve thermochemical reactions,that are primarily induced or driven by heat(or heating).These reactions are found in many industrial sectors,including waste management,metallurgy,power generation,heat supply,building material manufacture and so on.Thermochemical reactions are also the earliest chemical reactions that humans have recognized.They are essential to the processing of resources,the conversion of energy,and the technologies required for a circular economy.Additionally,thermochemical reactions are the main source of CO_(2)emissions,accounting for 90%of the total carbon emissions.For the goal of“carbon neutrality”,the innovation of thermochemical reaction science and technology should play major roles.The concept of“thermochemical reaction engineering”was proposed to refer to the science and technology for engineering chemical reactions.A highlight was made to identify the major advancements in science or technology for typical and great industries created based on thermochemical reactions.An analysis was also made to understand the opportunities for further techno-scientific innovations in“thermochemical reaction engineering”and their potential contributions to the strategy of“carbon neutrality”.Through carbon reduction,carbon substitution,and carbon recycling enabled by various innovatively new thermochemical reaction technologies,it was shown that an annual cut of up to 6 billion CO_(2)was potentially possible in the industrial sectors of China,especially from those“super emitters”of carbon dioxide.
