Abstract
A Long residue is a bottom product of an atmospheric distillation unit of crude oil. Generally this product is further processed in a refinery secondary unit to produce more yield. In case there is no refinery secondary process this bottom product is mixed with chemicals to produce marine fuel oil. This paper aims to describe the impacts of a long residue addition to the briquette quality of Ketapang or Terminalia catappa fruit and Siwalan or Borassus flabellifer L fruit skin charcoals using amylum as additive and a manual briquette machine. Each briquette composition consisted 10%, 20% and, 30% weight of long residue and, 5% weight of amylum. A manual briquette machine was used to mold the briquette. The Briquette results, then, were analyzed based on their proximate parameters and porosity. The analysis shows that the higher the long residue addition the better the briquette proximate analysis result. Some parameters such as porosity, moisture content and, calorific value fulfill the Briquette Indonesian standard nevertheless parameters such as FC, ash and, volatile matter contents need to be improved. These three last parameters relate to the raw materials chosen and, the performance of a charcoal furnace used. The compressive strength of the briquettes also does not fulfill the requirement as a manual molding machine was used for briquette process.
