| Description
| - The objective of this paper was to evaluate the effect of processing temperature and residence time on the biodegradability of wheat straw and to recommend sustainable process parameters for wheat straw treatment in industrial scale. The experiments were carried out with 5% content of raw wheat straw by weight in feedstock under processing temperature and residence time in ranges 170-200°C and 0-60 minutes. The biodegradation rate was evaluated by chemical oxygen demand, detailed analysis of saccharides, acids, inhibitors of fermentation, all by liquid chromatography, and by microscopic structure of wheat straw. Based on the experiments and detailed analysis it was concluded follows. The effectiveness of thermal-expansionary hydrolysis strongly depends on composition and initial pH of biomass, on processing temperature and residence time. The biodegradation rate of wheat straw grows up with increasing processing temperature and residence time. The expansion effect inflicts an intensive destruction of lignocellulosic structure. The maximum biodegrability was found to be at processing temperature 185°C and residence time in ranges 20-40 minutes. Treated feedstock by this way was well-pulpy and well-homogenized as well.
