摘　　要：基于煤炭在中美两国能源结构中的重要地位,指出洁净煤转化技术仍将是2050年前两国解决煤炭利用和环境问题的主导技术。本文阐述了先进煤化工涉及的洁净煤转化技术现状及发展趋势,重点以煤气化、煤液化、煤制烯烃和煤制乙二醇等技术为例,指出未来中美两国应优先在化学链气化技术、合成气一步合成低碳烯烃、煤炭转化系统CO2减排等核心技术发展,在化工作用机制、化学反应机理、高效催化剂开发、新型反应器设计等基础领域展开合作的战略建议。Considering that coal is of important status in the energy supply in both China and in the United States of America, this paper points out that clean coal conversion technology shall remain a leading technology in solving both countries’ coal utilization and environment issues before 2050. It reviews the current situation and growing trend of clean coal conversion technology involving advanced coal chemical engineering, with a focus on technologies in coal gasification, coal liquefaction, coal to olefins, and coal to ethylene glycol. This study points out that priorities should be given to the development of core technologies including chemical looping gasification technologies, one-step synthesis of low-carbon olefins from the synthetic gas, and CO2 emission reduction in coal conversion system. Strategic recommendations are put forward that collaboration should be done in fundamental part such as mechanisms in coal chemistry and coal chemical engineering, development of efficient catalysts, and design of new-type reactor.
