Abstract:
The production of bioenergy from biomass has been gaining significant attention as a sustainable alternative to fossil fuels. Corn cob biorefinery residues, typically treated as waste, present a valuable source of bioenergy due to their high calorific value and abundant availability. This work presents the results of lab-scale experiments with corn cob biomass. The first part of the work is focused on the proximate characterization of the studied biomass by applying the European and NREL standards. The work then focuses on the study of the acid hydrolysis of the biomass at constant temperature and different reaction time and sulfuric acid concentrations. The model attempted to find the optimum experimental conditions and the parameters that are statistically relevant to the process. Our target is to obtain high xylose yield, which will be transformed by one bioprocess using one selective yeast into xylitol, one important added value product to the bio economy, in this first part is presented same aspect from the Romanian agricultural market presenting from statistical dates the availability of the biomass. The second part of the work are focused to reuse the resulted solid fraction in the biomass treatment with dilute sulfuric acid ( 2%), The resulting solid fraction is the raw material in the pellet production phase. After drying, these residues were ground to a particle size of approximately 2-4 mm, which is the optimal particle size for pellet formation and helps achieve a high pellet density, 1.23- 1.3 g/ cm3. The optimal xylose 0, 3 g/ g biomass which can be transformed with biotechnological way in xylitol using Deboramicy Hanesy selective yeast wit 75 % efficiency.
