“…Engine performance indicates the effect of a fuel in the engine. It shows the trend and possibility of using distilled tire pyrolysis oil to replace diesel fuel without any engine modifications [16]. It is necessary to determine engine brake power, brake specific fuel consumption, and brake thermal…”

The standard of living, quality of life, and development of a nation depend on its per capita energy consumption. Global energy supply that mainly depends on fossil fuel is decreasing day by day. It is estimated that the energy demand will be increased five times by the year 2021 from present scenario. Due to the fossil fuel crisis, the development of alternative fuel technologies has drawn more attraction to deliver the replacement of fossil fuel. Pyrolysis is one of the promising alternative fuel technologies which produces valuable oil, char, and gas product from organic waste. Early investigations report that tire pyrolysis oil extracted from vacuum pyrolysis method seemed to have properties similar to diesel fuel. The main concern of this paper is to produce and improve the properties of crude tire pyrolysis oil by desulfurizing, distilling, and utilizing it with diesel in CI engine to analyze the efficiency for various compositions.

“…LDPE pyrolysis activation energy is estimated at 179-188 KJ/mol [14]. LDPE pyrolysis has less environmental impact, unlike the incineration of plastics which releases toxic and harmful emissions such as 5.04 CO 2 kg/LDPE kg [17,18]. Combustion of pyrolysis oils releases less CO 2 in comparison with LDPE incineration, with an average of 6 to 11.5% wt.…”

Abstract:The exponential increase of plastic production produces 100 million tonnes of waste plastics annually which could be converted into hydrocarbon fuels in a thermal cracking process called pyrolysis. In this research work, a direct current (DC) thermal plasma circuit is designed and used for conversion of low density polyethylene (LDPE) into diesel oil in a laboratory scale pyrolysis reactor. The experimental setup uses a 270 W DC thermal plasma at operating temperatures in the range of 625 • C to 860 • C for a low density polyethylene (LDPE) pyrolysis reaction at pressure = −0.95, temperature = 550 • C with τ = 30 min at a constant heating rate of 7.8 • C/min. The experimental setup consists of a vacuum pump, closed system vessel, direct current (DC) plasma circuit, and a k-type thermocouple placed a few millimeters from the reactant sample. The hydrocarbon products are condensed to diesel oil and analyzed using flame ionization detector (FID) gas chromatography. The analysis shows 87.5% diesel oil, 1,4-dichlorobenzene (Surr), benzene, ethylbenzene and traces of toluene and xylene. The direct current (DC) thermal plasma achieves 56.9 wt. % of diesel range oil (DRO), 37.8 wt. % gaseous products and minimal tar production. The direct current (DC) thermal plasma shows reliability, better temperature control, and high thermal performance as well as the ability to work for long operation periods.

“…Menurut Junary bahwa semakin lama waktu karbonisasi maka kadar air yang dihasilkan akan semakin rendah dan nilai kalor akan semakin tinggi karena kadar air berbanding terbalik terhadap nilai kalor [6]. Hal ini disebabkan oleh nilai kalor yang terkandung pada cangkang kelapa sawit cukup tinggi yaitu 3800 Kcal/kg [14] dan juga dipengaruhi oleh perekat yang digunakan yaitu oli bekas yang memiliki nilai kalor sebesar 45814,74 kJ/kg [26].…”

Briquette was a product of the compaction process of biomass residue used as fuel and it is formed using binder. Briquette from biomass has a high heating value. The quality of briquettes influenced by raw material composition and the time of carbonization. The carbonization process in the manufacture of briquettes could improve heating value and reduce smoke produced from burning briquette. This research is aim to study the effect of variations in the composition of raw materials and carbonization time on the heating value and the characteristics of the resulting briquettes. The materials used are palm fronds, palm shells, starch, used oil, H2SO4 and Tri Ethyl Amine (TEA). The ratios of palm frond and palm shell charcoal in this research is 1: 2, 1: 4, 1: 6 and 1: 8 with variation of carbonization time 30 minutes, 60 minutes, 90 minutes and 120 minutes. The research began with the carbonization process of the raw materials. Then charcoal product of carbonization was pressed using an binder starch and used oil as much as 20% based on the weight of raw materials at the ratio of 1: 1. The best quality from this research is obtained at the ratio palm fronds and oil palm shell 1: 8 with carbonization time of 120 minutes, heating value 15107,138 cal/g, moisture content 6%, ash content of 5,185%, volatile matter 39,226%, fixed carbon 70,955%, density 0,442 g/cm3, burning rate 0,273 g/min, and compressive strength 0,046 N / mm2. The result shows the briquettes produced had a strong structure, it was not easily broken and it was not moldy when stored.
