我国沿海地区进口煤炭发展煤制天然气前景分析

Prospect analysis of synthetic natural gas based import coal in coastal area of China

为探讨沿海地区发展煤制天然气的优势及必要性,阐述了我国煤制天然气的产业现状,分析了沿海地区进口煤炭制取天然气的竞争力,并提出发展前景。煤制天然气投资巨大,存在技术风险、管输及市场风险、环境污染等问题。沿海地区发展煤制天然气具有水资源丰富,接近终端市场,可进口优质、相对廉价煤炭等优势。2013—2014年,进口煤炭价格分别低于463、499元/t时能够保证11%的投资收益率,显著高于进口煤炭价格372~434元/t,说明沿海煤制天然气项目经济性良好。未来沿海地区进口煤炭发展煤制天然气应加强建设煤制天然气（SNG）/液化天然气（LNG）工厂、建立整体煤气化联合循环发电系统、发展煤制天然气为依托的分布式能源等。

To make clear of development advantage and necessity of synthetic natural gas based import coal in coastal areas,the present situation of synthetic natural gas based inland coal in China was expounded,the competitiveness of synthetic natural gas preparation based import coal in the coastal regions was analyzed,and the development prospect was put forward. The investment of synthetic natural gas was huge,it also had many problems such as technical risk,pipelining,market risk and environmental pollution problems. Abundant water resorous,conventient raw material importing channels and products sale channeals decided that,developing synthetic natural gas was feasibility in coastal areas. Between 2013 and 2014,the prices of import coal were less than RMB 463 and 499 per ton respectively,it could ensure return on investment of 11%,significantly higher than import coal price from RMB 372 to 434 per year,so the project of synthetic natural gas based import coal in coastal areas had better investment income. In the future,in coastal areas,it should strengthen the construction of coal-based SNG / LNG plant,establish the integrated gasification combined cycle power generation systems,develop distributed energy relying on synthetic natural gas project and so on.
