Abstract

This study of coal liquefaction in the absence of catalyst and solvent wasconducted. In this research a comparison of two different coals was carried out tosee characteristic of each coal on the liquefaction reaction. The effect ofhydrogen and CO/H2O were also checked to understand the mechanism of theprocess. Lignite or brown coal from Tanjung Enim and sub bituminous coal fromEast Kalimantan are used in this study. The results suggest that increase in coalrank from lignite to sub bituminous did not alter the conversion significantly.Surprisingly, the reduction in conversion of sub bituminous coal by its inorganicand mineral content noted for hydrogenation reactions (with added tetralin) is notobserved in CO/H2O reactions. For lignite, there is a tendency for conversion toincrease.Kata kunci: lignit, sub bituminous coal, non solvent hydrogenation

Abstract

Indonesia has potential abudant biomass wastes. Annual paddy production in Indonesia is approximately 50 million tons, from which 14 tons of rice husks is produced, assuming that each ton paddy could produce 0.28 tons of rice husks. At its calorific value of 12.5 MJ/kg, the annual potential energy provided by these husks is around 175 GJ. A gasification system using rice husk would normally require 1.5 to 2 kg of rice husks to generate 1 kWh of electricity. Therefore, each ton of rice milled could produce wastes that equals to electricity generation of 150 kWh. Rice husk is about 14 to 28.5% of a rice grain, but mostly has an average value of 25%. A gasification Bioner-1 system is operated 14 hours per day in 366 days per year. This system will drive a rice milling unit for 8 hours per day and produce electricity for villagers for another 6 hours in the evening. At a fuel consumption of 25 kg per hour, the system will require 130 tons of husks that will be provided from rice fields of around 175 ha. Gas (syngas) produced from the gasification will be used for a dual fuel diesel engine system, supplementing diesel fuel. The diesel fuel substituted by the gas could reach about 75-80%. At a consumption rate of 25 kg/hour rice husks in the system, the husks consumption per kWh electricity is 1.5 kg (1.5 kg/kWh) and the efficiency of rice husks conversion is 15%. A small portion of tar could still escape from a gas cleaning system. The tar could be observed during overhoul of the diesel engine. The tar entering into the diesel engine is overcome through switching on the diesel engine for about 10 minutes and flushing using diesel oil right before it is shutted down. Through this method, the tar entering the diesel engine is completely burned. Kata kunci gasification, biomas, rice husk, diesel engine

Abstract

Investigation of Limonite for catalyst on South Banko coal liquefaction werecarried out under standard condition which has developed by BPPT. LimoniteSoroako is a natural mineral that found at Nickel Mining on Soroako, SouthSulawesi.Four samples of limonite was examined using 5L autoclave at our coalliquefaction laboratory in order to investigate their activities to produce highdistillate yield at standard condition (450oC, 9MPa cold H2).The results showedthat limonite S99-E-MY gave a higher distillate yield than those of other limonite(difference about 10-30%daf coal or %bkta). Further investigations wereconducted to compare with other catalysts: synthetic g–FeOOH and pyrite (FeS2).Again, the activity of limonite S99-E-MY was still superior compared to those ofsynthetic and pyrite catalysts. The yield difference was about 10-16%daf coal or%bkta).Experiment revealed that the factor of FeOOH critically affected the coalliquefaction reaction to improve the distillate yield and to reduce CLB yield.Besides, the representative of Co metal in the limonite (≥5-10 %bk) could givesynergism effect with FeOOH to improve the activity of limonite.Kata Kunci: g–FeOOH, pyrite (FeS2), limonite, soroako, coal liquefaction

Abstract

Asam lemak bebas (alb) dalam Crude Palm Oil (CPO) merupakan salah satu parameter kualitas CPO.Munculnya asamlemak bebas ini dapat berasal dari faktor pemanenan dan penyimpanan. Asamlemak bebas yang tinggi dalam CPO dapat menurunkan harga CPO. Minyak mentah sawit inimerupakan salah satu sumber energi terbarukan yang diolah, antara lain, menjadi pure plant oil (PPO)dan biodiesel. Namun,masalah utama CPO sebagai bahan baku PPO dan biodiesel adalah asamlemak bebas. Asam lemak bebas dalam CPO yang dapat digunakan untuk PPO dan biodiesel tidakboleh lebih dari 1%. Oleh karena itu, dalam penelitian ini dilakukan usaha untuk menurunkan asamlemak bebas dalam CPO sehingga dapat dimanfaatkan sebagai bahan bakar. Metoda yang digunakanadalah esterifikasi. Asam lemak bebas dikonversi menjadi metil ester. Campuran metil ester dengantrigliserida ini merupakan bahan bakar yang dapat digunakan untuk pengganti BBM. Kondisi yangoptimal untuk proses esterifikasi CPO alb tinggi adalah sebagai berikut : suhu 65oC, waktu 360 menit,katalis 0,25%, dan perbandingan mol metanol 8:1. Dengan proses ini, asam lemak bebas dapatditurunkan menjadi 2,76% (konversi 89,39%). Pada kondisi yang sama dengan katalis yangditingkatkan menjadi 0,5%, asam lemak bebas dapat diturunkan menjadi 1,86% (konversi 92,85%).Pada kondisi yang sama, dengan katalis yang ditingkatkan menjadi 1%, asam lemak bebas dapatditurunkan menjadi 1,75% (konversi 93,28%).Kata kunci: asam lemak bebas, CPO, esterifikasi, PPO, biodiesel

Abstract

The latest status of the Coal Liquefaction project in Indonesia which had beenconducted over a decade is discussed. This paper provides some reviews of allactivities that have been made during the past 10 years under the collaborationbetween Japan and Indonesia. Currently, the situation has changed that coalliquefaction has been reconsidered as an important technology which should beimmediately introduced and demonstrated in Indonesia, not only because thecurrent oil price increased, but also in order to reduce the dependency onimported oil. This paper provides some suggestions and consideration on how topromote the Brown Coal Liquefaction (BCL) process toward commercialization inIndonesia. Since coal shares the biggest energy consumption in Indonesia, agreat measure of effective utilization of low grade coal is ultimately important,since almost 70% of the total 104 billion tons of coal resources are classified aslow-rank coal. In view of this situation, the promotion of coal liquefactiontechnology should be more accelerated. The comparison of inland and coastalsite mine-mouth coal lique faction plant is made to confirm the feasibility of bothperspectives for priority implementation.Kata kunci: coal liquefaction, feasibility study, coastal case
