Karakteristik Mekanik Briket Kokas Lokal Dengan Variasi Jenis Perekat

Abstract

The objective of this research is to examine the possibility of liquid smoke that are produce by carbonation process of coal, rice husk, coconut tree powder and mahogany tree powder as adhesives of local coke briquettes. The process of the research is begins with the preparing of raw materials such as coal, rice husk, coconut tree powder and mahogany tree powder. Every material are placed in a carbonation furnace with capacity of 10 kg, after that will be carbonation to a temperature of 300°C and held for 30 minutes with a heating rate of 10°C/min. The smoke that occur in a carbonation process is captured in a cool place in order to make a condensation process. The smoke that produced by condensation process is become a liquid smoke or tar. The next process, tar is as adhesive that is used in the process of making coke briquettes. Briquettes is tested by compressive strength, the length due changes of the pressure, impact resistance and water absorption. The results of this research show that the tar form mahogany tree powder have pressure resistance and long of pressure greater than others, however has a low impact pressure.
