This report is described with the current status of research and development of pilot plant.
The object of the R&D is to develop the technology to produce hydrogen from coal on a large scale and economically.
The Research Association for Hydrogen-from-Coal Process Development (HYCOL) has been receiving commission from the New Energy and Industrial Technology Development Organization (NEDO) and has been established.
The key technology of this gasification process has the following features:
Oxygen-blownone-chamber and twostep spiral flow gasification system:
This enables treatment of coal at a high temperature, leading to the higher gasi-fication efficiency and thus wider coal type utilization.
(2) Dry coal feed system:
This increases heat efficiency as well as product gas yield.
(3) Multi-burner system:
This can gasify a large amount of coal in a small but easy to scale-up gasifier.
Slag self-coating refractory with water-cooled tubes:
This can achieve long life of furnace wall and high reliability.
