Influence of microwave-assisted chemical treatment on delignification of rice straw biomass

open access: yesEnvironment Conservation Journal, 2021
Lignocellulosic biomass (like rice straw) provides an alternative for depleting non-renewable energy sources through its value-added utilization (like production of biofuels and nanocellulose) owing to its abundance, renewability, polymer presence and ...

Pengaruh Suhu Sintesis Katalis Partikel Ceria Zirconia terhadap Efektivitas Proses Delignifikasi

open access: yesJurnal Teknik Kimia dan Lingkungan, 2020
Biomass is organic material produced through photosynthetic processes. The presence of lignin on the cell wall will inhibit cellulose to be converted into products. Delignification will open the lignocellulose structure to make cellulose more accessible.

Effect of alkali delignification on wheat straw saccharification by fusarium oxysporum cellulases [PDF]

open access: yes, 1993
The effect of alkaline delignification of wheat straw on the chemical composition and the subsequent enzymic hydrolysis of the pretreated straw are reported. Both hot (120°°C) and cold (20–36°°C) delignification were investigated, using either aqueous or
