Summary: This study investigated the conversion of agricultural biomass waste (specifically, spent mushroom substrate) into syngas via pyrolysis. The experimental data highlight the important role of carbon dioxide (CO2) in enhancing carbon monoxide (CO) yield through gas-phase reaction. The addition of a Ni-based catalyst further enhanced the mechanistic role of CO2.

Summary: The purpose of this study was to investigate the impact of lignocellulosic composition in biomass waste on the microstructure and dye adsorption characteristics of microwave-assisted -ZnCl2 activated carbon. The results showed that cellulose is responsible for pore formation, while lignin is responsible for the presence of functional groups and pore size. Activation using ZnCl2 coupled with microwave heating creates uniform pores, and the adsorption ability of the activated carbon increases with an increase in the impregnation ratio. The activated carbon with the highest cellulose content exhibited the best adsorption ability.
