Abstract

The research of lubricant waste recycling by means of low rank coal as absorbent is one of the ways to render efficient the oil consumption also to maximize the value of low rank coal. This research is a continuation research with a fixed variable, in which the amount of coal is increased to 20% from the amount of the lubricating oil and the heating time which took 2 hours was variated with the heating temperature variable from 150°C to 350°C, the size of coal granule –8+10, -12+14 and –20+24 mesh. The research output shows that the optimum temperature of the lubricating oil recycling by means of coal as absorbent is reached in the temperature of 300°C for the coal with the size –12+14 mesh. In this condition Ca content reduce from 1447 to 150 ppm, Zn reduce from 887 to 17,4 ppm, Fe reduce from 47,1 to 43,5 ppm, Ni reduce from 15,4 to 6,2 ppm and Cr and Cu are all absorbed. The coal resulted from the recycling process can be used as a direct fuel with the calorific value between 5000 to 6500 cal/g and the colour of the lubricating oil resulted from separation (base oil) is yellowish dark.

Abstract

Coal seams D and E belong to the Muara Enim Formation in South Sumatra Basin, which includes to the Middle Miocene to Late Miocene. The research is located at the Air Laya coal mines, PTBA, Tanjung Enim, South Suma- tra. The purpose of this study was to investigate the characteristics of coal and coal depositional environments of Seam D (Merapi) and Seam E (Keladi). Observations were done on samples of coal from exploration drilling results from the Air Laya mining pit. The analysis is carried out by a petrographic analysis, which is supported by the results of coal vitrinite refl ectance.Petrographic characteristics indicate that both of seams D and E dominant macerals are vitrinite, the most dominant sub-group of vitrinite is telovitrinite. Inertinite in both seams consists of semifusinite, sclerotinite and inertodetrinite. Pyrite, clay mineral and carbonate are the main mineral in the seams. Vitrinite refl ectance (Rv- max,%) value shows similar rank of sub-bituminous to high volatile bituminous. Based on the results of coal depositional environment reconstruction using four parameters, which are the degree of preservation of plant tissue (TPI), the degree of Gelifi cation (GI), the degree of ground water infl uence (GWI) and vegetation aspects (VI), it is interpreted that seams D (Merapi) and E (Keladi) were deposited in upper delta plain depositional environment with ombrotrophic peat type.
