Effects of Sand-Clay Composite Binder on the Performance of Ecological Coal based on the Biomass of Eichhornia crassipes

Description

Ecological coal, to be effective, requires adequate know-how and above all a better composition of the inputs that go into its composition. The arid Sahelian zones have very few plants that can be considered as a binder in the production of ecological charcoal. For this is reason, it’s necessary to know how dune sand and clay available in the environment could be used as a binder provided that the proportions used are conducive to ensuring better energy performance in the final product. The ecological charcoal produced with Eichhornia crassipes, which is an invasive plant in fresh water, solves the ecological problems caused by its almost permanent and invasive presence. Thus its valorization as cooking energy is an option whose objective is to determine the effect of the sand-clay composite binder on the performance of the ecological charcoal based on the Biomass of Eichhornia crassipes as than cooking energy. The collection and sorting of these plants made it possible to prepare the raw material while their pre-treatment made it possible to carry out anaerobic carbonization between 400-600°C. Their physic-chemical characterizations made it possible to respectively obtain the average bulk density of the shredded material (ρapp) which is 823.94 ± 1.41 Kg/m3, the average humidity rate which is 4.54 ± 0.31 % and the average rate of volatile matter which is 12.83±0.73%. The performance of the green charcoal determined an average high ignition temperature of 308.22 ± 47.97°C, an average flammability time of 12 ± 1 seconds and an average maximum fire temperature of 958.33 ± 42.33°C. The burning and cooking test shows that the matched carbonized samples have a high ash heat (252.67±5.16°C) 30 minutes after burning, an average burn rate of 98% and a burn time of average of 448.05 ± 27.06 minutes.
