Due to moderate specific surface area(400—700m²/g), high porosity, high bulk density and adsorption performance, and no dust pollution during transportation of actived semi-coke monolith, it was carbon material with high added value. This paper was to summarize the main monolith and preparation processes of actived semi-coke, i.e. monolith activation process and activation monolith process, and review its progress in the flue gas desulphurization and denitrification, water treatment and fuel cell, meanwhile briefly analyze its adsorption mechanism and challenges in desorption. Thus more work should be carried out to further develop to the mechanism research on the monolith, adsorption and desorption, and industrial application and promotion of actived semi-coke monolith.

Key words: actived semi-coke, monolith, desulphurization, denitrification, water treatment
