On December 5, the Anhui Province major science and technology project \"1.7 million tons per year coal-to-methanol conversion to olefins project – Development of gasification technology using a fluidized bed with dry slag removal for coal with high ash fusion point\", undertaken by Zhongan United, passed the evaluation by an expert panel. The successful completion of this project opens up a new technical approach for the gasification of coal with high ash fusion point. Dong Zhongbing, deputy chairman of the Huainan Political Consultative Conference; Jiang Yong and Zhou Lijin, leaders of the company and its subsidiaries; representatives from the Anhui Provincial Department of Science and Technology, the Huainan Municipal Bureau of Science and Technology, project partners, as well as relevant staff from Zhong’an United attended the acceptance review meeting. Commissioned by the Anhui Provincial Department of Science and Technology, the Huainan Municipal Bureau of Science and Technology organized experts to conduct an evaluation of the provincial major science and technology project undertaken by Zhong’an United. During the acceptance process, the expert group listened carefully to the reports on the relevant work carried out by Zhong’an United, reviewed the associated technical documents, and inspected the project site in person. After inquiries and discussions, the expert group concluded that the project had met all the requirements specified in the contract, and agreed to approve its acceptance. This major provincial science and technology project was applied for and approved in 2015. The collaborating institutions on the project include Anhui University of Science and Technology, Nanjing Normal University, Anhui University, and Anhui Huahua Co., Ltd. The project focuses on studying the gasification performance of Zhujixi coal in SE-Eastern furnace systems, investigating the relationship between the gasification characteristics of coal with high ash fusion points and the agglomeration properties of ash residues, and developing a process model for dry slag removal in fluidized bed gasification. It is reported that the success achieved in the trial operation of the SE-Eastern furnace unit at Yangzi Petrochemical using Zhujixi coal, along with research on dry slag discharge technology and the future industrial application of related technologies, will completely change the historical situation in which Huainan coal could only be used as fuel coal rather than for chemical applications. This will play a positive role in improving the economic efficiency of enterprises and ensuring a stable supply of raw materials. Meanwhile, it holds significant strategic importance for Anhui Province and Sinopec in optimizing the allocation of resources.
