Hydrogen Production Technologies from Coal

Abstract

There are two main processes to make hydrogen from coal industrially. One is gasification process and another is dry-distilling process. The coal gasification furnace and the coke oven are known as equipments for gasified and dry-distilled coal, and those technologies are used for generating hydrogen widely now.

This report describes about the features and trends of more suitable gasification furnaces for generating hydrogen in the world and three attractive hydrogen manufacturing technologies, the HYCOL process, the HyPr-RING process and non-catalytic Hot COG reforming process.

The HYCOL gasification technology was promoted as the first technical development for hydrogen from coal by Japanese government. The HyPr-RING process is attractive attention from all over the world as new development technology of manufacturing hydrogen from coal and in-situ CO₂ capture. And, the non-catalytic Hot COG reforming process is the state-of-the-art technology for hot coke oven gas (hot COG) reforming.
