Peningkatan Nilai Kalor Biomassa Kotoran Kuda Dengan Metode Densifikasi Dan Thermolisis

Abstract

Direct combustion of horse dung as an alternative fuel has caused a lot of smoke and dust. Its efficiency and heating value were low. To improve its properties, the conversion method (densification and thermolysis) can be applied to increase the biomass heating value of the horse dung. The densification process was done using a mixture of starch and horse dung with the following ratio 1:3; 1:5; 1:7; 1:10. The results of the horse dung biomass then being processed by thermolysis (pyrolysis) using an oven with constant heating temperature and holding time, and with the addition of inert gas. Heating temperature and holding time are 300oC and 2 hours respectively. The results of testing conducted on the samples showed that the conversion of biomass horse dung in densification and thermolisis/pyrolysis were able to increase their heating value. The biomass briquettes with the ratio 1:10, were produce the highest heating value (dry heating value) i.e. 4708,775 kcal/kg. While bio-charcoal briquettes with ratio1:10 (thermolysis/pyrolysis results with the addition of inert gas), their highest heating value was 5002,791 kcal/kg
