Abstract:

费托合成技术能将煤、天然气和生物质等含碳资源间接转化为液体燃料,对于缓解我国油品资源短缺的现状具有重要意义。本文在介绍费托合成技术的原理以及微反应器优势的基础上,对费托微反应器的相关研究工作进行了总结。在反应器的类型介绍部分,分析了填充型和壁面涂覆型两大类微反应器各自的特点,与壁面涂覆型微反应器相比,填充型反应器有压降大、导热性能相对较差等问题,而在整体式微反应器中应用的催化剂层壁面涂覆技术则可有效地避免这些问题。在数值分析方面,指出费托合成相关的模拟研究主要集中在通过建立反应动力学模型,对微反应器内的温度场和产物分布进行分析,并对操作工况和反应器结构的设计提供依据。最后指出,目前费托合成微反应器在反应板片和冷却系统的结构优化与匹配设计、反应单元的组装、催化剂的壁面负载技术以及微反应器中的传输现象等研究领域,还有很多方面需要研究,在未来微反应器中费托合成技术会得到更大的发展。
