People's Daily Online, Beijing, May 8 (Reporter Du Yanfei) A reporter from CNOOC Refinery Co., Ltd. (hereinafter referred to as CNOOC) learned that my country has made new progress in the application of coal gasification and hydrogen production technology. As of May 7, it is located in Huizhou, Guangdong. my country's first coal-to-hydrogen combined unit using E-Gas technology has been running continuously and smoothly for over 270 days, with a cumulative production of over 55,000 tons of hydrogen, helping the clean and efficient utilization of coal.
my country's energy structure has the basic characteristics of "rich coal, lean oil, and little gas".
The Central Economic Work Conference in 2021 proposed that based on the basic national conditions of coal-based, we should focus on the clean and efficient utilization of coal, and promote the optimal combination of coal and new energy.
Industry insiders believe that in order to promote the clean and efficient utilization of coal, it is necessary to realize low carbon emission and no carbon emission through low-carbon technology innovation, accelerate the transformation of coal from fuel to raw material, and highlight the raw material properties and diversified and efficient utilization of coal.
As one of the important ways to realize the effective utilization of coal resources, coal-to-hydrogen uses coal as a reducing agent and steam as an oxidant, and converts carbon into syngas mainly composed of carbon monoxide and hydrogen at high temperature. After purification, carbon monoxide conversion and purification and other links to produce hydrogen and syngas.
"Gas coal-to-hydrogen combined plant has the characteristics of high carbon conversion rate, high heat utilization efficiency, and low oxygen consumption. Compared with the traditional natural gas-to-hydrogen production process, the cost can be reduced by 20% to 25%." COSL Huizhou Petrochemical Coal-to-Production Zhou Jianxin, deputy manager of the hydrogen department, introduced that since 2018, Huizhou Petrochemical has independently developed the whole-process automation control system for the configuration gasifier, organized the localization of imported equipment such as coke filter backflushing valves, filter elements, and carbon recovery facilities, and introduced optical fibers. Temperature measurement technology, developed and summarized the operation method of waste heat boiler and low-load operation method of sulfur unit, and realized the smooth operation of E-Gas coal-to-hydrogen combined unit under different loads.
