Intensification of hydrolysis of wheat straw polysaccharides with diluted acids due to new heat and mass transfer equipment

Current research directions in the development of next-generation environmentally sustainable processes for the chemical conversion of lignocellulosic biomass focus on the application of efficient and cost-effective catalysts that enhance the chemical transformation of lignin and polysaccharide components. A comparative evaluation of the concentrations of reducing sugars and total solids in wheat straw hydrolysates obtained through hydrolysis with diluted hydrochloric and phosphoric acids were conducted. The performance of novel heat and mass transfer equipment, including a rotary-pulsation apparatus, was assessed with the aim of intensifying the hydrolysis of wheat straw polysaccharides. It was determined that the integration of advanced heat and mass transfer systems, particularly the rotary-pulsation apparatus as the core technological unit, results in an increase in the concentration of reducing sugars and total solids in the hydrolysates by approximately 20?25% and 10?15%, respectively, compared to conventional processing technologies.
