(490q) Comparative Analysis of Corn Stover Components and Non-Conventional Biomass Feedstocks with Diluted and Concentrated Acid Hydrolysis

Although ethanol can be made from a wide range of biomass materials, corn stover from corn production is a crop residue readily available today, so it is easily accessible to plants that already produce ethanol from corn starch, in the same way existing non-conventional crops for saccharification process from the tropical region that have had little attention, have the benefits to be found in large quantities and in an industrial level are completely separated into its components with a free access for acid or enzymatic hydrolysis. The objectives of this work is to develop a comparative analysis between concentrated and diluted acid hydrolysis processes of corn stover components (stalks and leaves), mango (skin and bagasse), and coconut shell with the effect of some hydrolysis parameters in production of monomerics sugars using sulfuric acid. The variables considered were the effects of the hydrolysis temperature, time in both processes; furthermore in the concentrated acid hydrolysis it was considered the percent by weight and in the dilute acid hydrolysis the acid concentration. Also, the biomass was subject to pretreatments like alkaline hydrolysis, liquid hot water and steam explosion was used. Hydrolysis of biomass resulted in a glucose concentration (mol/m3) reported and compared with the data obtained through identical experimental designs and statistical analysis techniques of all cellulosic feedstocks.
