Preparation of Acetic Acid by Hydrothermal Catalytic Oxidation Degradation of Cellulose Simulants

Abstract:

A hydrothermal catalytic oxidation degradation process was investigated to improve acetic acid production from cellulose simulants. Filter paper, being a cellulose simulant as the test material, was oxidized in a batch reactor with catalysts. An L¹⁶(45) orthogonal array design (OAD) with five factors at four levels was employed. Of the five, reaction temperature was the most influential for the yield of acetic acid. Afterwards, a series of process optimization experiments were conducted. And a higher yield of acetic acid (28.53%) was obtained under the following conditions: temperature was 320°C; reaction time was 26 min; water consumption was 8 ml; oxidant and catalyst supplied were 0.8% and 0.2% of the raw material respectively.
