“…Afterwards, it moves to the heater and into reactor-101 to carry out cracking reactions. The cracking reactions in the reactor were similar to the aforementioned process reactions, as presented below: methyl ricinoleate methyl undecenate þ di-isopropyl-ketone (4) methyl undecenate methyl caprylate þ propadiene (5) methyl ricinoleate 2-methylenehexanal þ methyl caprylate þ propylene (6) methyl ricinoleate ricinoleic acid þ methane 7methyl ricinoleate methyl linoleate þ water (8) methyl undecenate 1-decanol þ CO 2 (9) methyl ricinoleate 1-dodecanal þ cyclopentylacetic acid (10) The output stream from the reactor entered into heat exchanger-108 after a thermal exchange was conveyed to heat exchanger-109. The temperature of the stream is reduced to 250°C.…”

“…Since fossil fuels have been increasingly consumed and are considered as serious pollutants for the environment within the last 80 years, it is vital to replace them by alternative fuels [1][2][3][4][5]. One method is optimizing the quality of diesel and gasoline fuels by making changes in the formulation [6][7][8][9][10][11][12]. Another solution would be substituting biofuel and biodiesel for fossil fuels [13][14][15].…”

The transesterification process with potassium hydroxide (KOH) catalyst and the methanol supercritical process were evaluated by Aspen HYSYS software. Castor oil and methanol were used as feed and alcohol. In order to accomplish verification, the simulation results were compared to a laboratory research. For economic analysis, these results were transferred to Aspen Economic Analyzer software. Piping and process equipment cost were calculated for the two processes. Additionally, direct and indirect costs of these processes were estimated.

Experiments were carried out to reduce the harmful exhaust emissions from the engine through various in‐cylinder techniques such as nanoparticles blended fuel. In this present investigation, the effect of methanol‐gasoline fuel blends (M10, M30, and M50) and neat gasoline (G100) on a single‐cylinder four‐stroke SI engine was studied under idle throttle operating conditions to obtain the characteristics of total fuel consumption and exhaust emissions. The fuel‐borne nanoparticles such as aluminum oxyhydroxide [AlO(OH)] from 50 to 150 ppm were mixed with methanol gasoline blends. AlO(OH) behaves like a fire retardant which prevents detonation and knocking under a higher concentration of methanol gasoline blends. The SI engine was running without any problem using gasoline–methanol blends up to M50 under idling and acceleration. However, the engine was running under idling conditions using neat methanol (M100) and failed to run under acceleration due to poor combustion under a rich mixture. The total fuel consumption decreased with the use of methanol and significant reductions were observed on engine surface temperature, exhaust gas temperature, and the exhaust emissions such as carbon monoxide, hydrocarbons, and nitrogen oxide when compared with neat gasoline.

“…In contrast, carbon dioxide and nitrogen oxides emissions increased. Zamankhan et al [11] and Valihesari et al [12] used a new combination of fuel with oxygenate additives and metal nanoparticles in a spark ignition engine to study the effects of the novel blends on the engine parameters and also the amount of emissions. Based on their results, the performance parameters of the engine were improved and the amount of pollutants was reduced.…”

In this study, effects of adding butene, homopolymer to gasoline on the performance of a four-stroke spark ignition (SI) engine and pollutant emissions have been investigated. This additive increases the octane number of gasoline. In this research, the additive was combined with a non-leaded gasoline. Also, in addition to fuel changes and the use of additives, engine spark plugs were replaced and three types of spark plugs were used for this study. These include single electrode spark plug, dual electrode spark plug and Platinum+4 spark plug. The results of experimental tests showed that with the addition of additive to gasoline, the brake torque and braking power were increased with the use of each of the three spark plug type. The results revealed that by combining gasoline and additive, carbon dioxide and nitrogen oxides emissions were increased. On the other hand, unburned hydrocarbons and carbon monoxide emissions from the engine were reduced. In addition, it was concluded that changing the spark plugs had slight effect on engine performance and pollutant emissions, and that the results of experimental tests using all three types of spark plugs were almost identical.
