Study on cassava stalk as briquette binder

Introduce the research status of preparing bio-briquette binder with cassava stalk at home and abroad.Propose the concept that development and utilization of cassava stalk plays an important part in energy conservation and environmental protection.Discuess the possibility of modifying cassava stalk with NaOH.Conduct single factor experiment,investigate the influence of mass fraction of NaOH,heat treatment temperature and time,additive amount of cassava stalk on the compressive strength of briquette.At last,the technological parametres were optimized by orthogonal design experiment.The results show that the additive amount of modified biomass binder is the main cause.The compressive strength of bio-briquette can reach 563 N per sample when the mass fraction of NaOH is 2%,heat treatment temperature is 95 ℃,heat treatment time is 2.5 h,modified biomass binder accounts for 20%.
