Abstract: The effect of high-temperature reforming method on the performance of commercial wooden molding activated carbon materials prepared by phosphoric acid activation was studied. The effects of different heating and cooling modes,reforming temperature and reforming time on the strength of activated carbon materials were investigated. The results showed that when the activated carbon were heated to 800℃ by rapid heating-up and reformed for 30-75 min before rapid cooling (fast heating/fast cooling (FH/FC)),the strength of activated carbon increased by 5.75%-6.39% and the yield of activated carbon maintained more than 83.54% which was higher efficiency than that by the method of gradient increased temperature/natural drop (GI/ND) in temperature. The pore structure and adsorption capacity of activated carbon after reforming at 800℃ for 30 and 60 min were also studied. The results showed that the specific surface area and total pore volume of activated carbon decreased by about 400 m2/g and 0.3 m3/g, respectively. The proportion of pores with pore size distribution smaller than 1.2 nm was increased. The adsorption capacity of methylene blue showed a small decrement. The adsorption capacity of iodine was slightly increased. The butane working capacity was decreased less than 15%. After high-temperature reforming,the ignition point of activated carbon significantly was increased. When activated carbon reformed for 60 min at 800℃,its ignition temperature improved by more than 100℃. It mainly related to the reduction of the amount of oxygen functional groups on the surface of activated carbon after high-temperature reforming.
