Abstract
The main aim of this research was to investigate proximate analysis and heating value of wet cake waste from ethanol industry to be used as alternative fuels by carbonization at 400, 450, 500 and 550 degrees, vary times 30, 45, 60 and 90 minutes in oxygen-limited conditions. The maximum yields and fixed carbon volume were observed to be evolving at 500c, 60 minutes. At condition has 1.17% moisture, 34.42% ash, 16.57% volatile matter and 47.84% fixed carbon respectively.Then bring wet cake waste to briquette charcoals by hot and cold compressed for utilization in industry and commercial. Found that heating value of hot and cold compressed were 20,257.25 KJ/kg and 24,790.21 KJ/kg,which are higher heating value after carbonization.There are also cost-benefit and cost-effectiveness analysis, hot compressed cost 0.17 baht/piece, total production at breakeven 704,225 pieces and payback period of 0.18 years, while cold compressed cost 0.3175 baht/piece, total production at breakeven 341,297 pieces and payback period of 0.17 years.
