Hydrogen, as the cleanest green fuel, was officially classified as an energy source by the National Energy Administration on April 10, 2020, heralding an explosive surge in demand for hydrogen energy. Dakote Company boasts advanced technologies for hydrogen production via natural gas reforming, coal-to-hydrogen conversion, and methanol steam reforming, enabling it to meet diverse hydrogen supply needs across small, medium, and large scales. Its hydrogen products achieve purity levels that satisfy industry standards for chemical synthesis, semiconductor manufacturing, and fuel cells.

　　(1) Natural Gas Reforming for Hydrogen Production

　　Extensive optimization and improvements have been made to the process technology and equipment for hydrogen production via natural gas reforming, encompassing the reformer configuration, desulfurization system, shift conversion system, decarbonization and PSA purification system, as well as the integrated heat recovery system. As a result, the overall capital investment and energy consumption of the hydrogen production unit are significantly lower than those of conventional processes.

　　Technical Features and Advantages

　　µ Applicable to hydrogen production from feedstocks such as natural gas, shale gas, coalbed methane, biomass gas, LPG, and light oil.

　　µ Advanced and mature hydrogen production technology, rational plant configuration, and low overall investment.

　　µ The reformer’s structural layout has been thoroughly optimized, ensuring safe and efficient operation.

　　µ The decarbonization and PSA purification system features high hydrogen recovery, efficient and comprehensive waste heat utilization, and low operating costs.

　　µ The process is simple to operate and highly automated.

　　µ Depending on the scale of hydrogen production, hydrogen production units can be modular, integrated, and skid-mounted, with a rational layout that minimizes land footprint.

　　µ Employs low-nitrogen control technology, ensuring that flue gas emissions meet environmental protection requirements.

　　(2) Coal-to-Hydrogen Technology

　　Hydrogen production from coal is currently the most cost-effective method and is well suited for large-scale operations. Coal is subjected to processes such as dry distillation and gasification to produce raw coal gas, water gas, synthesis gas, coke-oven gas, and other syngas streams. These syngas streams are then pre-treated to remove impurities—including benzene, naphthalene, tar, and sulfur—and subsequently purified through techniques such as wet carbon removal, pressure swing adsorption (PSA) for hydrogen recovery, and hydrogen purification to obtain high-purity hydrogen products.

　　Technical Features and Advantages

　　µ Applicable to large-scale hydrogen production from various coal-derived syngases.

　　µ Advanced and mature hydrogen production technology, rational plant configuration, and low overall investment.

　　µ The purification process features high integration, resulting in high hydrogen purity and yield, as well as low hydrogen production costs.

　　µ The process is simple to operate and highly automated.

　　(3) Methanol-to-Hydrogen Technology

　　Methanol-to-hydrogen technology is well suited for small- and medium-scale hydrogen users that lack access to feedstock for hydrogen production. Although the cost of hydrogen produced via this method is higher than that from coal gasification or natural gas reforming, it offers greater operational flexibility. Dakote has long provided advanced turnkey methanol-to-hydrogen technologies and equipment to a wide range of customers.

　　Technical Features and Advantages

　　µ Methanol-to-hydrogen technology is advanced and mature, with safe and stable operation.

　　µ Flexible adjustment of hydrogen production load to meet diverse user needs

　　µ The hydrogen production process is simple and requires a small footprint.

　　µ The process operation is simple, with a high degree of automation, enabling network-based remote monitoring and unattended operation.

　　µ Optionally, the byproduct food-grade CO₂ from the PSA decarbonization unit can be sold, and the desorbed gas generated during PSA purification can be compressed and recycled, further reducing methanol consumption.
