YangMei group with three sets of coal chemical industry, ethylene glycol, Japan PuJing Gao Huaxue, Shanghai, China five rings were used respectively to three kinds of technology, but the catalyst must be purchased, seriously affect the enterprise economic benefit. Based on integration of existing coal catalyst for ethylene glycol technology, urged the company to research and develop the coal catalyst for ethylene glycol project, perfect the YangMei chemical industry chain, improve the existing coal glycol unit economic benefits. More important is through the catalyst research and development process to understand the advantages and disadvantages of various coal ethylene glycol and catalyst, and integration of existing coal glycol technology, eventually forming YangMei coal group with independent intellectual property rights for ethylene glycol production package. In rush company is conducting related scientific research test, according to the test progress, in the rush company test in catalyst under the condition of high performance, considering YangMei chemical existing device based on pilot test side, according to the pilot situation gradually develop further work arrangement.
