CATALYTIC ACTION OF MOLTEN ALKALI IN CONVERSIONOF BIOMASS TO POROUS CARBONSChesnokov N.V. 1,2 , Mikova N.M. 1 , Ivanov I.P. 1 , Kuznetsov B.N. 1,2PP-121 <strong>Institute</strong> <strong>of</strong> Chemistry and Chemical Technology <strong>SB</strong> <strong>RAS</strong>,K. Marx str., 42, Krasnoyarsk, 660049, fax: +7(391)2439342, e-mail: inm@icct.ru2 Siberian Federal University, Svobodny pr., 79, Krasnoyarsk, 660041As known, the molten salts are in catalytic processes <strong>of</strong> coal and biomassgasification and liquefaction. Catalytic action <strong>of</strong> molten KOH and NaOH in thermalconversions <strong>of</strong> wood, lignin and cellulose was studied in this work.It was shown that the molten hydroxides <strong>of</strong> alkaline metals promote the significantdevelopment <strong>of</strong> solid raw material porous structure. The specific surface area, totalvolume and size <strong>of</strong> the pores depend on the nature <strong>of</strong> raw material and alkalihydroxide, ratio raw material/alkali hydroxide and on the temperature <strong>of</strong> activationtreatment. The optimal conditions <strong>of</strong> alkaline activation <strong>of</strong> various raw materials wereselected which allow to provide the maximal development <strong>of</strong> nanoporous structure <strong>of</strong>produced active carbons.When wood biomass is used as a raw material, the carbonization with KOHincreases by 5-10 times the specific surface area <strong>of</strong> produced active carbons in thecomparison with traditional carbonization process. It was found that the wood natureinfluences on the texture characteristics <strong>of</strong> active carbons produced by alkalinethermal treatment. The maximal surface area <strong>of</strong> active carbons from birch-woodreaches 2050 m 2 /g, when the same for aspen-wood active carbons is no more than1350 m 2 /g.The specific surface area <strong>of</strong> nanoporous carbons obtained by carbonization <strong>of</strong>cellulose and wheat-straw lignin in the presence <strong>of</strong> molten KOH goes through amaximum with the increase <strong>of</strong> KOH/raw material ratio. The maximal surface area <strong>of</strong>carbons from cellulose reaches to 1700 m 2 /g and for wheat-straw lignin –to 2040 m 2 /g.Sorption properties <strong>of</strong> active carbons prepared by alkaline activation <strong>of</strong> differenttypes <strong>of</strong> natural raw material were studied. They are active in sorption <strong>of</strong> molecularhydrogen and different hydrocarbons (trichlormethane, benzene, alcohols etc.). Asidefrom the nature <strong>of</strong> initial raw material the sorption capacity for H 2 increases with thegrowth <strong>of</strong> micropores volume <strong>of</strong> prepared active carbons.101
