According to Sinochem News, recently China’s first project to achieve 100% efficient conversion of coke oven gas was put into operation at Liaoning Anji New Energy Technology Co., Ltd. This project converts all the industrial exhaust gases generated in steel production into clean energy and chemical products with high added value, opening up a new path for the green and low-carbon development of integrated steel production. According to Cai Xinbo, the project manager of the company, the project has overcome numerous industry challenges thanks to its independently developed core technologies. The project adopts a full-process technology of \"pre-treatment and purification + efficient conversion + product purification\". First, high-precision filtration techniques are used to remove impurities such as sulfur and naphthalene from coke oven gas, ensuring a stable and efficient conversion process thereafter ； Subsequently, using a new type of catalytic reaction device, components such as hydrogen and carbon monoxide in coal gas are converted into high-purity syngas, which can then be processed into high-value chemical products like methanol and ethylene glycol, or used as a clean fuel in industrial production and domestic applications. Compared to traditional technologies, this project achieves a conversion efficiency increase of over 30%, with the product purity reaching 99.9%. This project achieves \"converting one type of waste into three materials\" by using separation techniques to extract methane, nitrogen-hydrogen components, and hydrogen from coke oven gas, which are then used respectively to produce liquefied natural gas (LNG), liquid ammonia, and high-purity hydrogen. Industry insiders say that as the world’s largest coke producer, China generates approximately 210 billion cubic meters of coke oven gas annually. If 30% of this is converted efficiently, it could reduce carbon dioxide emissions in the steel industry by around 45 million tons per year, while generating additional economic value of over 100 billion yuan.
