摘要
Abstract
As a basic energy source and chemical raw material with abundant reserves in China,coal's clean and efficient conversion and utiliza-tion are of great significance.Coal-to-olefins,coal-to-ethylene glycol,and coal-to-natural gas are key pathways for transforming coal resources into high-value-added chemicals and clean energy.This article introduces the production methods of these three processes:coal-to-olefins involves coal gasification to produce syngas,which is then converted into methanol,followed by methanol-to-olefins(MTO,MTP)for olefin production;the oxalate ester method is currently a widely discussed technology for coal-to-ethylene glycol in China;coal-to-natural gas centers on the methana-tion of syngas,completing the conversion of coal into substitute natural gas.Meanwhile,this article provides a detailed overview of the current de-velopment status of each process.Although these technologies have reached industrial scale,they still face common challenges such as improving energy efficiency,reducing carbon emissions,and controlling costs.This article provides a basis for the high-quality development of the coal-based chemical industry.关键词
