It is necessary to separate CO from biogas to improve its quality for the production of biomethane. Herein, an improvement in the separation of CO/CH adsorption was achieved by modifying the surface of CMS. The surface modification of CMS was performed by impregnation with metal oxide (FeO) and N-doping (DES-[ChCl:Gly]).

Dispersion of iron oxide is one of the critical factors which supports the separation process performance. Iron oxide dispersion can be enhanced by enriching the oxygen functional groups on the carbon surface.

Lignocellulose pretreatment is an important step to obtain an eco-friendly, economical, and effective biomass utilization process. The combination of microwave heating and hydrotropic pretreatment is considered as a green method of lignocellulose pretreatment.

- - This study investigates how rice husk can be broken down into sugars using sulfuric acid, examining different concentrations of the acid during the hydrolysis process.
- - It finds that at higher acid concentrations (over 0.44 N), the process is better explained by a heterogeneous model, while at lower concentrations, both the homogeneous and heterogeneous models are applicable.
- - The research shows that the rate of hydrolysis is influenced by the transfer of sulfuric acid into the rice husk particles and that the sugars produced can be turned into ethanol through fermentation with yeast.
