Abstract

In accordance with the mandate of the Regulation of the Indonesian Minister of Energy and Mineral Resources for the use of cleaner coal through coal gasification projects, in the future the coal gasification industry will produce char as a by-product. This study aims to characterize coal gasification char using a prototype underground coal gasification (UCG) and the addition of coconut shell charcoal biomass as a raw material for making biobriquettes. By using coal as raw material from the Muara Tiga Besar Mine of PT Bukit Asam, five kinds of coal samples from different layers were obtained, which from the characterization results, both coal and char, did not have too significant deviations so that the research variables could be ignored. The results of the characterization of char from coal gasification results compared to the initial sample of coal showed an increase in calorific value, a decrease in sulfur content and a significant decrease in water content, so it can be concluded that char from coal gasification has good potential as a raw material for biobriquettes. By using char and coconut shell charcoal with the ratio of variations in the composition of char and coconut shell compositions is 100%:0%; 75%:25%; 50%:50%; 25%:75% and 0%:100% carried out the briquetting process. The results of the biobriquette characterization met the criteria of the Indonesian National Standard (SNI) 01-6235-2000 and Minister of Energy and Mineral Resources regulation No. 047 of 2006

Abstract

Coal reserves in Indonesia are estimated at around 26 billion tons and will still be primary energy until 2050. This makes the use of green coal and clean energy an urgent homework. One of the uses of coal is coal gasification. From the results of coal gasification, a by-product is obtained, namely char. In this char characterization, it is found that char has an increase in fixed carbon and GCV values as well as a significant decrease in sulfur content. This makes char potentially a raw material for environmentally friendly solid fuels (briquettes). The addition of biomass in the form of coconut shell charcoal is expected to increase the calorific value and allow ignition from low temperatures which can then save the time and energy needed for briquetting ignition and maintain the combustion rate. Therefore, as an initial study, it is necessary to study literature from previous studies as the basis for the initial hypothesis of the addition of coconut shell charcoal in the manufacture of briquettes with the main raw material of char from coal gasification
