查询词典 biomass

Cornhusk is a kind of non-food and low-cost biomass. Cornhusk was hydrolyzed by dilute acid in this research. Optimized technical conditions for detoxification of cornhusk dilute acid hydrolysate were determined by experiments: activated carbon 1%, pH4.0, temperature 30℃, detoxification time 30min.
