Abstract To solve the fire accidents caused by coal combustion, this work prepared four hybrid hydrogel materials using
bio-based polymers, flame retardants, and inorganic materials. Compared to pure water and 3.5 wt% MgCl2 solution, the as-prepared hydrogel presents good fire prevention performance. In addition, it is found that CO and
CO2 are not produced by coal when the pyrolysis temperature is lower than 200°C. During low-temperature pyrolysis, CO is more likely to be produced than CO2, indicating inadequate pyrolysis behavior. At the same time, the
addition of fire-preventing hydrogel can not only decrease the maximum CO2 concentration before… More >
