The honeycomb activated carbon produced by Hebei Feixiang Environmental Protection Equipment Co., Ltd. has a well-developed pore structure and a large specific surface area.
Its adsorption and purification effects are very extensive. It adsorbs sulfur dioxide, nitric oxide, carbon disulfide, carbon tetrachloride, hydrogen sulfide, as well as substances such as benzene, aldehydes, phenols, esters, ketones, etc. Such as gasoline, diesel, phosgene, and substances containing heavy metals and foul odors.
Honeycomb shaped activated carbon is made from a mixture of Yunnan Qujing lignite, Shaanxi Shenfu bituminous coal, Shanxi Datong bituminous coal, and additives. It is extruded, carbonized, and steam activated The samples were analyzed and characterized using N2 adsorption, pressure testing, and hot weather testing methods.
The results showed that coal type and activation degree significantly affect the pore structure, ignition temperature, and mechanical strength of honeycomb shaped activated carbon. Honeycomb shaped activated carbon prepared from Datong coal has a high specific surface area (884m2/g), ignition temperature (535 ℃), and mechanical strength (13MPa). The mechanical strength of coal based honeycomb activated carbon decreases with the increase of large pore volume. The ignition point of coal based honeycomb activated carbon is inversely proportional to its volatile matter content, and not related to its ash content.
