The effect of oxygen-enriched air on low-rank coal char combustion was experimentally investigated. In this work, a coal-heating reactor equipped with a platinum wire mesh in the reaction chamber was used to analyze the combustion temperature, reaction ti... see more

The upgrading Kalimantan low rank coal is performed using slurry dewatering process in a stirred batch autoclave (inner volume of 5 liters) equipped with a condenser, a pressure control valve (PCV), and a receiver. The experiment is carried out at 3.5 kg/... see more

Lignite is the lowest rank coal which has less economic value. Corn cobs are solid waste biomass as a by-product of corn processing. The processing of these two materials can produce a product in the form of hybrid coal through the co-pyrolysis process. T... see more

Lignite is classified as a low-rank coal due to its low content of calories. Co-pyrolysis with biomass waste such as palm empty fruit bunches (EFB) here can be used to increase lignite’s economic value. The mixture of these two materials can produce an al... see more

This research was conducted on the Bobong Formation coal in the form of geochemical analysis. The Bobong Formation is geologically located in the Banggai Sula Basin, Pulau Taliabu Regency, North Maluku Province. The study focused on low rank coal on the l... see more

The Muaraenim Formation is a coal bearing formation in South Sumatra Basin of the Late Miocene – Pliocene. Shell (1978) divides this formation based on coal seam content are: M1, M2, M3, and M4. Coal seam in this area include in seam M2 member, with the g... see more

Khyber Pakhtun Khwa province of Pakistan has considerable amounts of low ranked coal. However, due to the absence of any centrally administered power generation system there is a need to explore indigenous methods for effectively using this valuable energ... see more

The production of electrical energy from burning of coal produced  large amounts of fly ash waste. Fly ash had the potential to be used as soil ameliorant material because it has a very fine size. The purpose of the research was to to develop a new a... see more
