基于灰色预测、趋势外推法、组合预测3种模型,预测了新型煤化工的几种主要产品2020年前的供需缺口,并结合煤炭未来的产能情况,得出2020年煤炭的盈余量还不能满足煤化工几种主要产品缺口的耗煤量,并提出了相关建议。
Based on the three models of gray forecast, trend extrapolation and combined forecast, the forecast of the supply and demand gap of several main products of new coal chemical industry before 2020 and the future production capacity of coal shows that the surplus of coal in 2020 can not be obtained Coal coal to meet several major product gaps in coal consumption, and put forward relevant recommendations.
