The Analysis of the distribution of available mesopores in cellulosic pulp, using Inverse Size Exclusion Chromatography-ISEC

The Analysis of the distribution of available mesopores in cellulosic pulp, using Inverse Size Exclusion. Chromatography-ISEC The aim of the presented research was to determine available mesopores in cellulose masses obtained by industrial methods. Cellulose masses obtained from fast-growing poplar species (Populus sp.) can be used in the production of biofuels of the second generation. One of the factors influencing the effectiveness of hydrolysis is the availability of pores in the material for acids and enzymes used during this process. For this purpose the reverse spatial exclusion chromatography (ISEC) with the use of dextran standards and selected sugars was applied to verify the distribution of available mesopores in cellulose masses. The analysis showed the material with the highest share of available pores, the selection of which will allow to increase the efficiency and profitability of biofuel production from lignocellulosic materials.
