(175l) Subcritical aqueous phase oxidation of the waste generated from alkaline pretreatment of lignocellulosic biomass

Subcritical aqueous phase oxidation of the waste generated from the alkaline pretreatment of lignocellulosic biomass (LCB) was performed in a batch reactor in the presence and absence of homogeneous and heterogeneous catalytic material. The aqueous stream obtained after the oxidation step was analyzed by TOC analyzer, HPLC, GC-MS. Concentrations of C1-C3 carboxylic acids were quantified using HPLC whereas organic intermediates were analyzed by GC-MS using appropriate calibration methods. Results obtained with reduction in TOC, concentration of C1-C3 acids and identification of the intermediates will be presented.
