Fuel oil is one of the important parts to support daily activities. The demand for fuel oil is increasing every year. Therefore, the search for the latest energy source is continuously conducted. Carica papaya L. seed oil is investigated as a renewable energy source replacement part of petroleum diesel fuel. C. papaya seed oil obtained through the extraction process using soxhlet method with n-hexane solvent. Then produce methylester by means of transesterification using 1 % NaOH catalyst and 20 % methanol of the weight of the oil and stirred at 400 rpm for 1 h. A mixture consisting of 10 % C. papaya seed biodiesel and 90 % petroleum diesel fuel, called CPSB-10, produces fuel properties that meet the specified standards by the Indonesian Directorate General of Oil and Gas. From the result of the performance test in a diesel test engine, the maximum brake power and brake thermal are consecutively 30.6 kW and 140.23 N m, the lowest sfc is 268 g kW–1 h–1, and the highest brake thermal efficiency is 32 %.

The future of fossil fuel sources of energy has necessitated the need to search for renewable alternatives. Thus, Carica papaya seed oil (CPSO) was employed as feedstock for the production of biodiesel by methanolysis. The seed was obtained locally, dried, and extracted with n-hexane. The CPSO was analyzed for specific gravity, viscosity, iodine value, and saponification value, among others using standard methods. The oil was transesterified by two-stage catalysis with oil to methanol mole ratio of 1 : 9. The biodiesel produced was subjected to standard fuel tests. The seed has an oil yield of 31.2% which is commercially viable. The kinematic viscosity of the oil at 313 K was 27.4 mm2s−1 while that of Carica papaya oil methylester (CPOME) was reduced to 3.57 mm2s−1 and the specific gravity was 0.84 comparable with other seed-oil biodiesels and number 2 diesel. Other oil properties were compared favourably with seed oils already documented for biodiesel synthesis. CPOME’s cloud and pour points were 275 K and 274 K, respectively, and relatively higher than other biodiesels and number 2 diesel. CPOME exhibits moderate corrosion of copper strip. The methanolysis improved the fuel properties of the CPOME similar to other biodiesels. CPSO therefore exhibits a potential for biodiesel production.

The purpose of the research. The relevance of the article is due to the decline in the consumption of petroleum products in the world and in Russia in particular, as well as changes in the structure of demand for petroleum products. The crisis related to the COVID-19 factor had a significant impact on the oil and petroleum products market. Consequently, this article is aimed at identifying the prospects for the development of the oil product market. Results. The leading approach to the study of this problem is the analysis of current indicators of the oil product market, which allows a comprehensive review of current market trends and prospects for its development. Based on the analysis, it can be concluded that in 2020, the volume of primary processing is expected to decrease, which will not suffer as much as the production of crude oil. However, all markets are expected to recover in 2021. It should be noted that the production of products aimed at the domestic market (automobile gasoline and diesel fuel) has increased in recent years. Fuel oil and gas oil production, which is export-oriented, decreased compared to 2014. Exports of petroleum products such as motor gasoline, diesel fuel, bitumen, and vacuum gas oil have not changed significantly over the past few years, while exports of fuel oil have declined significantly. The reduction in production and export of fuel oil is associated with a drop in the attractiveness of fuel oil exports as a result of an increase in export duties. In the future, diesel fuel production and exports are projected to increase, while fuel oil production and exports will continue to decline. The article has a practical value for companies working in the oil refining industry, public and private investors.

Papaya Seed

Papaya is the most beneficial fruit for human health. In addition to the fruit that can be consumed, it turns out papaya seeds can also be used. In addition to the seeds used to be planted as well as only being waste, oil can also be obtained from papaya seeds. One method for obtaining papaya seed oil is a method of extracting heat (requires installation in the process), in general the notion of reflux is extraction with a solvent at its boiling temperature point, for a certain time and the amount of solvent adjusted to air temperature. In this research, papaya seed extraction was carried out, percent yield analysis was carried out, and heavy type analysis of papaya seed oil extraction was carried out. The purpose of this study was to study the variation in extraction time of papaya seeds with solvents on the yield of oil produced. This research was carried out by reacting papaya seeds with hexane solvents at 65 ℃. Where the weight of papaya seeds is 50 gr, and the volume of solvents varied by 300 ml, 400 ml, and 500 ml and the reaction time is 120 minutes, 150 minutes, and 180 minutes. The results showed that the largest papaya seed oil was 34.2% at a volume of 500 ml solvent for 180 minutes and a high density of 0.87 gr / ml at a volume of 500 ml solvent for 180 minutes.Keywords: Extraction, hexane, papaya seed oil, reflux

 The rate of fossil fuel consumption is soaring with population growth but the fossil fuel reserves are finite in nature. It is only a matter of when they run out - not if. Every year, billions of tons of fossil fuel oil is consumed globally. So it is high time we contemplated over other alternative fuels. One such alternative is the use of Straight Vegetable Oil (SVO) or its blend in diesel engine if performance, emission and maintenance of an engine are comparable to diesel fuel. The main objective of this research was to evaluate the effectiveness of commercially available Soybean oil and diesel blends on the performance characteristics of Kirloskar single cylinder diesel engine. This study also sheds light on comparison and measurement of physical properties of diesel and test fuels i.e., the blends, and correlates them with the performance test result. It is concluded that the tested blends can be used safely and effectively in the diesel engine, at least in small blending ratios with normal Diesel fuel.
