Summary:Title screen
An idea about porosity development in porous carbons from vegetable biomass due to mineral phase leaching from the carbonized feedstock was investigated. As raw materials, wheat bran and rice husk were used. For comparison, two sedimentary feedstocks (highly-mineralized peat and coal) were also utilized. The raw materials, at the first step, were treated via oxidative carbonization in a fluidized catalyst bed reactor at 465, 550, and 600°С, followed by removal of mineral template phase through acid leaching. It was found that this approach allows for obtaining porous carbons with specific surface area up to 369 m2·g−1 and pore volume of 0.28 cm3·g−1. The materials were characterized by SEM and Raman spectroscopy. It was also discovered that in the case of biomass feedstocks, porosity development via mineral phase removal is more effective, while for the peat the increase in texture characteristics is poor, and for the coal - texture properties of porous carbons remain practically the same. Such a result can be explained by different properties of the mineral template phase of the sedimentary feedstocks, which depend on a mineral component accumulation mechanism.
