In recent years, China’s coal chemical industry has been thriving, with continuous breakthroughs in technological innovation and process optimization. The number and scale of facilities for producing high-purity hydrogen from coal as feedstock have been steadily expanding. The typical process flow comprises oxygen-enriched continuous gasification, syngas desulfurization, carbon monoxide shift conversion, and pressure swing adsorption (PSA) for decarbonization and hydrogen purification. Our company is capable of supplying complete coal-to-hydrogen plants as well as individual process units.

Carbon-dioxide-rich gas streams such as lime-kiln gas, flue gas, and fermentation gas typically operate at low pressures. By employing Dacot’s low-pressure pressure-swing adsorption (PSA) technology for carbon dioxide recovery, these streams can be concentrated, further purified, and liquefied to produce industrial-grade or food-grade carbon dioxide products.

Our company has independently developed the DKT-6 active catalyst and adopted a wet oxidation desulfurization process that absorbs H2S from fuel gas and coal gas at ambient temperature, eliminating the need for thermal regeneration and enabling the co-production of sulfur. This process features low operating costs and reduced overall energy consumption. It exhibits broad compatibility with varying H2S concentrations in the feed gas, and a single-stage desulfurization step can ensure that the H2S content in the purified gas is below 100 mg/Nm³; moreover, depending on requirements, it can even reduce H2S levels to as low as 50 mg/Nm³.

Natural gas sweetening to remove C₂ and heavier hydrocarbons
Our company employs pressure swing adsorption technology to remove C₂ and heavier hydrocarbons from natural gas, achieving removal of impurities other than methane to levels below 100 ppm in a single step, thereby facilitating the fine chemical utilization of natural gas.

Our company has developed a novel, proprietary adsorbent that effectively removes carbon dioxide from associated gas in oilfields. The recovered methane meets the specifications for pipeline transportation, and the CO₂ removal efficiency exceeds 98%, enabling its direct application in enhanced oil recovery. This approach not only reduces separation costs and lowers CO₂ emissions but also purifies the methane.
