coal chemicals

The work of the paper is as follows: ( 1) Non-linear characters of the coal chemicals price time series can be determined according to BDS methods.

工作内容主要有三方面：（1）根据BDS检验方法确定煤化工产品的甲醇价格时间序列的非线性性质。

It is widely used in metallurgy, mining, coal, chemicals, ceramics and other industries.

它广泛应用于冶金 、 矿山 、 煤炭 、 化工 、 陶瓷等行业.

The first was the conversion convert to petrochemical from coal chemicals.

第一次产业结构调整的目标是实现煤化工向石油化工的转化；

With growth of coal chemicals and natural gas chemicals, methanol output in China will rise greatly and development of products from methanol become imminent.

随着煤化工和天然气化工的发展，我国甲醇产量将有较大幅度的增长，甲醇下游产品的开发迫在眉睫。

Our products widely adapted to the metallurgical, power, coal, chemicals, ports, terminals, food and transport sectors.

产品广泛适应于冶金 、 电力 、 煤碳 、 化工 、 港口 、 码头 、 粮食和交通运输部门.

From the viewpoints of technical development, process flow path and use in coal chemicals, an introduction is given to the technology of shell pulverized coal gasification under pressure and that of the new GSP process.

从技术开发、工艺流程、煤化工上的应用等方面对Shell粉煤加压气化技术和新型气流床粉煤加压气化技术加以介绍。
