COMPARATIVE ANALYSIS OF DIFFERENT ACIDS UTILIZATION FOR CELLULOSIC HYDROLYSIS BY USING BRAZILIAN WOOD WASTES FOR FIBERS AND BIOETHANOL PRODUCTION YIELDS

This paper main objective is to determinate the hydrolysis efficiency by using four different diluted acids treatment: (H2SO4) sulfuric, (HNO3) nitric, phosphoric (H3PO4) and acetic (CH3COOH), in attempt to improve the fibers and bioethanol production levels. In this study twelve Brazilian woods wer...
