Abstract

Transportation is an important means for modern society to facilitate the mobility of people and goods.The transport sector consumes about 30% of the total national final energy consumption. In 2016,energy consumption in the transportation sector reached 331.7 million BOE (equivalent barrels of oil)with a fuel mix of 55.3% gasoline; 14.0% of diesel oil; 22.3% biosolar; 0.04% fuel oil, 0.07% natural gas;0.005% avgas, 8.15% aviation fuel and 0.04% electricity. The increasing demand for energy in thetransportation sector in Indonesia is largely due to the improvement and addition of transportinfrastructure in some parts of Indonesia, especially airports and the growth of low-cost airlines. In2050 it is projected that the use of gasoline and diesel oil will continue to increase with growth of 4.0%and 4.5% per year. Along with this, the growth of biodiesel continues to increase to 7.9% per year.While avtur utilization is projected to continue to grow with a growth rate of 6.8% per year.

Abstract

Sei Pagar's palm oil mill (PKS Sei Pagar), PTPN V Riau processes fresh fruit bunch into crude palm oil(CPO). This processing also generates waste like empty fruit bunches (EFB), shells, fiber, and palm oilmill effluent (POME). POME has a high content of chemical oxygen demand (COD), approximately30,000-80,000 mg/L, which is usually fermented by bacteria. This fermentation mechanism can beused to produce biogas containing methane in a continuous stirred tank reactor (CSTR). Since POMEor organic materials for biogas production generally contain sludge, the biogas production processshould have an agitator to mix sediment in the base reactor and improve biogas production. Thisresearch aims to determine the agitator's specifications for the biogas pilot plant in PKS Sei Pagar,consisting of power type and type of stirrer include diameter calculation, geometry, and powercalculation. The agitator's power and geometry are determined based on input data from the datasheetreactor and the efficiency of the stirrer is calculated by Reynolds reynolds numbers. From thisresearch's calculations, an agitator geometry for the biogas pilot plant in PKS Sei Pagar had a length of0.875 m, a width of 0.7 m, and a height of 3.5 m. This research also obtained that the motor power resultwas 23.55 HP. The selection of motor power in the Biogas pilot plant's stirring process in PKS Sei Pagarshould have a standard agitator motor power of 25 HP.

Abstract

Renewable energy development for power generation is in line with the government's program toincrease the share of renewable energy in the national energy mix which is relatively small at themoment. BPPT, collaborating with PTPN 5 in the Insinas Flagship program, built a pilot plant for biogasproduction from Palm Oil Mill Effluent (POME) with a capacity of 700 kW. The reactor used in this pilotproject is a Continuous Stirred Tank Reactor (CSTR) which is the most important operating unit forproducing biogas from POME. Therefore, the selection of the CSTR foundation is crucial since themain process occurs in the reactor. The scope of this activity is to realize the final design into theconstruction of a CSTR pilot plant. Several types of foundations were studied, starting from shallowfoundation type such as tread foundation, deep foundation, until combining shallow foundation typewith deep foundation type. The evaluation of existing data and design review indicates that the use ofMat Foundation is not suitable due to soil condition at a depth of 0–5m which is in the form of sandyloam soil with an NSPT value of less than 20. The selection of Piles is based on the calculations usingtotal vertical load of 3035,37 ton and total horizontal load of 542,57 tons. Considering the availability ofmaterials and time concern, the recommended foundation type is pile with a diameter of 600 mm typeB and a length of 12 m.

Abstract

The influence of solvent was examined in the single- and two-stageliquefaction of Tanito Harum coal with FeNi supported oil carbon black(FeNi/KB) and a synthetic pyrite. FeNi/KB catalyst provide a high oi l yield inthe single-stage liquefaction when tetralin or 1methylnapthalene wasused, while pyrite (FeS2) gave a low oil yield in the liquefaction with 1-methylnapthalene although it produced a high enough oil yield in theliquefaction with tetralin. The single-stake liquefaction of coal gave extremelylow oil yields under the solvent free conditions for all catalysts examined. Inthe liquefaction of coal with solvent, the difference of oil yield producedbetween single-stage and two stage is small. However, the conversion of H--donor solvent after liquefaction was much lower than that of single-stageliquefaction. In the free-solvent liquefaction coal, two-stage liquefactionproduced much higher oil yield than single-stage.Kata kunci: solvent, catalyst, single-stage coal liquefaction, two-stage coalLiquefaction

Abstract

Indonesian brown coal, South Banko coal, was liquefied into oil in the presence ofcarbon monoxide and water using alkali base catalyst, NaAlO2. Liquefaction testwas carried out using microautoclave in the absence of donor solvent. Experimentwas conducted at 365oC and 400oC in order to examine the effect of temperatureon coal conversions.Kata kunci: south banko, brown coal, liquefaction, catalyst, donor solvent

Abstract

The effect of adding sulfur in Central Banko coal liquefaction is examined usingautoclave reactor with limonite catalyst from Soroako, at 450oC, H2 initialpressure = 9 Mpa, holding time = 60 minutes, and S/Fe ratio varies from 1, 2, 3dan 6. It is found that there is significant increase in distillates yield by 53,81% forthe increase of S/Fe ratio from 1 to 2, and at the same time CLB decreases from53,5% to 29,47%. This is because the amount of pyrrhotite for S/Fe ratio =2 ishigh and enough to promote cracking to convert coal to distillates or oil. For S/Feratio = 3, the increase of distillates or oil yield is not significant, so does for S/Fe= 6. This concludes that adding more sulfur in Central Banko coal liquefactionusing limonite catalyst from Soroako is not effective and therefore does notinfluence much to the oil yield. This is because the particle size and amount ofpyrrhotite already achieves equilibrium for S/Fe ratio = 2. The changing of S/Feratio does not give much effect to the yields of H2O, CO+CO2, C1~C4,andhydrogen consumption as well..Kata Kunci : limonit Soroako, rasio S/Fe,yield distilat, yield CLB, pirhotit, yieldH2O, yield CO+CO2, yield C1~C4, konsumsi gas hidrogen

Abstract

B r o w n Coal Liquefaction (BCL) process had been developed through theconstruction and the operation of 50 T/D pilot plant Ill Australia (1985-1990) byKOBE STEEL Group. After the successful completion of the Pilot Plant Project,newly Improved BCL process has been developed1). The feasibility study onthe commercialization of coal liquefaction plant in Indonesia has also beencarried out under the cooperation with BPPT supported by NEDO Limonitore (α-FeOOH) can be used as an industrial catalyst for direct coal liquefactionwith its high activity and low production cost. In this paper, the catalytic activitiesof Indonesian limonit ore, Soroako Limonit were examined using a gas flow typeautoclave comparing with the other iron catalysts for the liquefaction ofIndonesian brows coal. It appeared that the Soroako limonit has a highcatalystic activity while finely pulverizing to sub-micron particle size can bedone economically. It can be concluded that Soroako limonit is one of mostsuitable catalysts for the coal liquefaction plant constricted in Indonesia in thefut-ure.Kata kunci: direct liquefaction, soroako limonit, iron catalyst, phyrrotite, bankocoal

Abstract

The output of electricity for power plants and output of steam for industrialfurnaces related with flue gas concentration, such as fly ash (dust), CO, CO2NOx, and SO2. The condition of flue gas product is very important for estimatedthe actual level of emissions, because it product depends on type of plant,operating conditions, maintenance, and on fuel properties. The consequence ofcoal combustion, a considerable increase in emissions of dust, hydrocarbon,NOx and SO2 is to be expected. Therefore, to use the abatement technology,such as filters, desulphurization plants, de-nitrification unit, fluidized bedcombustion, and integrated gas combined cycle power plants for reducing theconcentrations of flue gas is an appropriate choice.Kata kunci: coal combustion, flue gas, emission
