Microwave-assisted depolymerization of lignin with synergic alkali catalysts and a transition metal catalyst in the aqueous system

Abstract

In this study, synergic alkali catalysts(NaOH+NaAlO2) and Ni/ZrO2 were used to lignin depolymerization with microwave-assisted. Effect of temperature, alkali dosage, Ni/ZrO2 dosage, and solid-to-liquid mass ratio were studied to improve...

Optimization of activated carbon production from corn cob using response surface methodology

“…Conventional pyrolysis is achieved using a bath furnace with high thermal inertia and low electricity conversion efficiency (Arpia et al, 2021). Microwave-assisted pyrolysis has a higher efficiency in the heating process because energy transfer is facilitated through the interaction of molecules inside the biomass rather than heat transfer from external sources (Zi et al, 2019;Li et al, 2022). The main advantages of microwave heating are shorter retention time, better overall efficiency, and a faster and more controllable process (Elsa and James, 2017;Arpia et al, 2021;Yu et al, 2022).…”
