多联产是煤化工的发展方向

多联产是一个非常复杂的系统工程，其实质是通过以煤气化技术为“龙头”的多种煤炭转化技术的优化集成，实现煤炭资源价值的梯级利用，从而达到煤炭资源价值提升，利用效率和经济效益的最大化，同时做到煤炭利用环境最好友。希望国家能尽早成立专门机构，统筹规划，进行人才，技术，资金等资源的优化配置，充分调动各方面的积极性，集中各地业的优势力量，加速多联产的研究开发和产业化发展进程。

Integrated Co-Production - the Development Direction of Coal Chemical Engineering

The integrated co-production system of coal conversion with coal gasification as the basically technology is considered to be a very complicated system engineering. The new system can realize the graded utilization of coal resource value by the optimum integration of several coal conversion technologies, so as to realize the maximization of value improvement, utilization efficiency and economic benefit during the utilization of coal resources. The system will also be friendly to the environmental protection during coal utilization. A specialized agency should be set up as early as possible to comprehensively plan, optimize the distribution of the resources such as manpower, technique and finance, activate the powerful research force in the whole country.
