Abstract

The development of coal gasification has several disadvantages including high reaction temperature and big energy consumption, difficult purification of the gaseous products, and stringent requirements of the process equipment. It has also been pointed out to cause serious environmental pollution. In this study, the experiment was conducted by flowing nitrogen, oxygen, and , into the gasification equipment. The gasification reactor was heated to 600 oC, 700 oC and 800 oC, where dry coal had been initially fed into before the gasification process began. The flow rates of pyrolysis products were then measured and a sample was taken for further analysis by using a gas chromatograph. The analysis identified the products composition that was CO, CO2, H2, CH4, C2H4 and C2H6. The composition of synthesis gas was observed to depend on the gasification agent used. it can be summarized that there is a good correlation between gasification agent and coal used, with the quality and quantity of synthesis gas produced.

Abstract

Banjarbaru has a very complex and interesting geologic condition.  The stratigraphy in this area has a unique and complex characteristic, with Pre-Tertiary until Quarterly in age.  The oldest type of rock found has a Yura-age, consists of: Ultra-mafic rock (Mub) and Metamorphic rock (Mm). Both of these rock-types outspread unconformity under a Pre-Tertiary lithological units (Kapur), likes Keramaian Formation (Kak), sedimentary of volcaniclastic Pitanak Formation (Kvpi). These Pre-Tertiary rocks laid unconformity under a group of Tertiary and Quarterly age of lithology, consists of: Tanjung Formation (Tet), Berai Formation (Tomb), Dahor Formation (TQd) and alluvium sedimentation (Qa).Gemstone deposit, included in its type and occurrences, conducted by long geological processes.  As known, the Regional Geology of Kalimantan, especially inSouth Kalimantanregion, has proceeded in age of Pre-tertiary until Quarter.  This process supported the forming of gemstones and its accumulation.  Kinds of gemstones and semi-gemstones probably accumulated by this geology process which consists of: primary diamond, tourmaline, blue-sapphire, Jade, Garnet, Secondary diamond, Quartz, Zircon, Spinel, opal, etc. Nowadays, the real potency of gemstone and semi-gemstone has not been known yet, so an effort of follow-up exploration is needed.
