Comparative Studies on Combustion Characteristics of Blended Crude Jatropha Oil with Magnetic Liquid Catalyst and DEX under Normal Gravity Condition

Abstract

A comparative study on the combustion characteristics of a single droplet fueled by DEX, crude jatropha oil (CJO), and a mixture of CJO with a magnetic liquid catalyst of rhodium trisulfate has been carried out under normal gravity conditions. The high viscosity of crude jatropha oil makes it difficult to burn under normal conditions (room temperature and atmospheric pressure), therefore the addition of a magnetic liquid catalyst rhodium trisulfate is needed to improve the properties of crude jatropha oil. As a catalyst, rhodium trisulfate has the potential to improve combustion performance while improving the physical properties of crude jatropha oil as an alternative fuel for the better. Furthermore, performance tests were also carried out with DEX fuel with a cetane number (CNs) 53. The results showed that compared to DEX, it was seen that the liquid metal catalyst rhodium trisulfate succeeded in making crude jatropha oil more charged so that the combustion process was better. This is evidenced by a significant change in the dimensions of the flame and an increase in the combustion temperature. Moreover, it is also seen that the burning rate increases and the ignition delay become faster.

Effects of Eugenol and Cineol Compound on Diffusion Burning Rate Characteristics of Crude Coconut Oil Droplet

“…This analysis is clarified from the results of the combustion test data (see Figure 6). Moreover, it is also per the results of our previous study using a mixture of crude jatropha oil and liquid catalyst, which are discussed from different points of view [34].…”

“…The formation of H2O molecules has the potential to cause a natural transesterification process so that the carboxyl group on the triglyceride carbon chain breaks and separates from the fatty acids. This analysis follows previous studies, which used crude jatropha oil droplet fuel without additives but underwent a preheating process to produce hot steam in the form of H2O molecules, which contribute to breaking the carboxyl group from fatty acids [33], [34].…”

Characterizing of Nano Activated Bio-Carbon of Sago Waste as a Homogeneous Combustion Catalyst

“…Moreover, the structure of the CCO carbon chain compound (see Table 2), which is composed and dominated by short carbon chains with little mass (Lauric 31%, Myristic 18.45%, caprilic 8.54%, palmitic 8.4%), makes it polar so that it has the potential to increase the attractive and attractive interactions and reactivity of these molecules. This analysis is by some of our previous studies [21], [39], [40] which also used CCO as fuel, Morinda citrifolia oil, as well as crude jatropha oil and crude sunflower oil, and this analysis even clarified from the graph of FTIR test results (see Figure 5). It can be seen that the CCO fuel molecules with NABc begin to absorb transmittance (T) of infrared (IR) energy at around 104%T, whereas without NABc, it is around 89%T.…”

Artificial Neural Network-Based Modeling of Performance Spark Ignition Engine Fuelled with Bioethanol and Gasoline

“…This analysis is reasonable because the polar and branched OH groups demonstrate the reactive nature of the BE50 molecule, as evidenced by its higher thermal efficiency than gasoline. This analysis follows our previous research using liquid metal-based additives and is discussed differently [26]- [28]. The network is successfully trained and then tested data is used to evaluate the selected network.…”
