In the recent years, the economic and environmental issues have increased the scientific interest in the use of lignocellulosic biomass, particularly in the discarded biomass. Agro-industrial biomass, consisting of ligno-cellulosic waste, is an abundantly available renewable energy source and an extremely cost-effective and efficient natural resource for energy generation. In this context, green biotechnology has been an extremely promising approach to converting the bulk of solid agricultural waste, especially lignocellulosic materials, into energy fuels and materials that can handle large polluting loads. There is no doubt that important steps have been taken in the utilization of lignocellulosic biomass and its position on the green energy market possesses a big proportion. In the current dissertation, barley straw is used as raw material, for the production of adsorbent materials and improved fuel.
Using the torrefaction method, the straw was thermally treated at temperatures of 200, 220 and 240 ° C and at residence times of 20, 40 and 60 minutes for each temperature. The result of this treatment is that the calorific power of the straw increased significantly in relation to its initial as well as its adsorption capacity, which was measured in a simulated adsorption process, using a methylene blue solution.
