With the development of China's industrialization and urbanization process will continue to accelerate, oil imports increased year by year, increasing dependence on imported petroleum products, net oil imports had reached 136.17 million tons in 2005, 42.9% dependence on foreign oil, Although in recent years has declined, but remains a serious threat to China's political security and economic development [1]. industry in line with China's national conditions. The traditional coal chemical industry, environmental pollution, low efficiency problem must go, for the sustainable development of the coal chemical industry, industrial ecology route in recent years, the country has completed a batch of coal chemical eco-industrial park. However, due to the defects of the beginning of the construction of ecological industry chain design and production of the limitations of the technology of choice, leading to the loose structure of the part of the industry chain enterprises to build disorder, can not reach the coal maximize economic benefits and environmental friendly requirements, and so on to evaluate ecological industry chain of coal chemical analysis and optimization is necessary. This thesis is based on the theory of ecological industrial, the Jinjie Industrial Park of Yulin City coal chemical industry chain for the object of study, structural analysis, and found the existing problems, propose ways to design and optimization of ecological industry chain of coal chemical optimization program . Its main results are as follows: (1) the existence of the problem of the low level of development, the level of technology and equipment behind, poor ability to resist risks, lack of economic momentum, the lack of information exchange between enterprises of China's coal chemical industry chain, from the economic and environmental benefits industrial development on our existing industry chain of coal chemical ecology of structural adjustment, the need to optimize the design. (2) According to the Yulin City, Jinjie Industrial Park, the existing status quo of industrial chain, industrial chain composition analysis and building evaluation index system for analysis, evaluation of coal chemical industry chain structure, pointed out that the current lack of a single industry chain structure, length and degree of coupling The security system is not sound. (3) structural characteristics of the industry chain of coal chemical ecology and construction method, ecological industrial chain optimization study to optimize the analysis, in accordance with the requirements of the eco-industrial school, from the leading industry chain and system integration of Yulin City Jinjie Industrial Park coal chemical industrial chain and intravenous industrial chain optimized design. The optimization results show that, by the introduction of the MTO, MTP and acetic acid derivatives and other projects, optimize and increase the use of solid waste, wastewater ways, can be an effective solution to the lack existing industry chain structure is simple, the length and the degree of coupling effectively enhance the raw materials the utilization of waste. (4) from the support facilities, government support, financial support, etc., the the Jinjie Industrial Park chain of coal chemical industry security system optimization recommendations. Promote education, the introduction of technology, financial security, government support, policymakers to strengthen and improve the existing ecological industrial incubator and information exchange platform based on to enrich its commitment to the task and content.
