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.
