Abstract

The use of coal as primary energy in Indonesia will continue to be carried out, although slowly it will experience a significant decline until 2050 by the mandate of the National Energy Policy and the General National Energy Plan; this is more or less due to the potential of national coal reserves of 38.84 Billion Tons. However, planning for green coal or clean coal must be the first step by providing added value for coal through downstream coal gasification methods where the pilot project will be held at PT Bukit Asam as a state-owned enterprise. Coal gasification will produce by-products in the form of char which allegedly still has energy potential. As an effort to recycle when that pilot project is going operation, this char is then used as raw material to make briquettes. In this preliminary research, using coal samples with seam variation from PT Bukit Asam and the gasification process produces some char. After char characterization result by proximate and ultimate analysis, it is found that char experiences an increase in Gross Calorific Value grades from 5,804 cal/gr to 6,183 cal/gr (seam A1), from 5,794 cal/gr to 6,281 cal/gr (seam A2), from 5,837 cal/gr to 6,320 cal/gr (seam B1) and from 5,898 cal/gr to 6,407 cal/gr (seam C) and a significant decrease in sulfur levels from 1.18% to 0.38% (seam A1), from 0,41% to 0.30% (seam A2), from 1.12% to 0.59% (seam B1) and from 1.19% to 0.69% (seam C) and also a significant decrease of inherent moisture from 16.10% to 12% (seam A1), from 15.10% to 11.40% (seam A2), from 17.6% to 10.30% (seam B1) and from 14.8% to 9.9% (seam C). This result makes char potentially a raw material for solid fuels that are environmentally friendly.

木炭气化作为一种环保燃料的潜力
印度尼西亚将继续使用煤炭作为初级能源,但根据国家能源政策和国家总能源计划的规定,到2050年将缓慢地大幅度减少;这或多或少是由于全国煤炭潜在储量388.4亿吨。然而,绿色煤炭或清洁煤的规划必须是第一步,通过下游的煤炭气化方法为煤炭提供附加值,试点项目将在武吉阿萨姆PT Bukit Asam作为国有企业进行。煤气化将产生以焦的形式产生的副产品,据称焦仍具有能源潜力。当试点项目开始运作时,作为一种回收利用的努力,这种木炭被用作原材料来制造压块。在这项初步研究中,使用了武吉阿萨姆PT煤层变化的煤样品和气化过程产生的一些炭。根据近端分析和终端分析结果,发现煤焦总热值等级从5804 cal/g增加到6183 cal/g(煤层A1),从5794 cal/g增加到6281 cal/g(煤层A2),从5837 cal/g增加到6320 cal/g(煤层B1),从5898 cal/g增加到6407 cal/g(煤层C),硫含量从1.18%减少到0.38%(煤层A1),从0.41%减少到0.30%(煤层A2)。从1.12%降至0.59%(煤层B1),从1.19%降至0.69%(煤层C),固有水分从16.10%降至12%(煤层A1),从15.10%降至11.40%(煤层A2),从17.6%降至10.30%(煤层B1),从14.8%降至9.9%(煤层C)。这一结果使炭有可能成为环境友好型固体燃料的原料。
