Thermal Degradation of Nopal (Opuntia Ficus Indica) Derived Biomass

Nopal biomass thermal decomposition occurs in up to four events between 200° and 700°C. Most weight loss is in the 200-400 °C range, referring to cellulose and hemicellulose depolymerization and decomposition. With acid catalyst (30% ZrO₂/SiO₂), the second event shifts to lower temperatures and may effect depolymerization and/or monomer decomposition.
