Abstract

The depletion of fossil fuels, rising of earth temperatures and declining of air quality are an unavoidable phenomenon today. This condition is a result of increased and excessive use of fossil fuels. Bioethanol fuel is one solution to reduce this problem that is sourced from renewable raw materials. Sorghum seeds are raw materials that have the potential to be made bioethanol due to they have a high carbohydrate content (70%). The test is performed the use of pertalite-bioethanol blends fuels was on a four-stroke gasoline engine without modification. The percentage of the mixture volume of fuel used is 10% bioethanol-90% pertalite (E10), 15% bioethanol-85% pertalite (E15) and 20% bioethanol-80% pertalite (E20). Engine speeds vary from 1000 to 4000 rpm, and properties of the sorghum seeds bioethanol-pertalite blends are measured and analyzed. The purpose of this study is to investigate engine performance and exhaust emissions at gasoline engine by using the sorghum seeds bioethanol-pertalite blends with different mixed ratios (E10, E15 and E20). The Engine performance includes engine torque, brake specific fuel consumption (BSFC) and thermal brake efficiency (BTE) analyzed. In addition, carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) emissions are measured as gasoline engine exhaust emissions. The results show that BSFC decreased while BTE increased for a fuel blends containing 20% bioethanol at 3500 rpm engine speed, with each maximum value of 246.93 g/kWh and 36.28%. It is also found that CO and HC emissions are lower for the sorghum seeds bioethanol-pertalite blends. Based on the research results, it can be concluded that the sorghum seeds bioethanol-pertalite blends can improve engine performance and reduce exhaust gas emissions.

Abstract

Biodiesel is biodegradable and non-toxic and has a low carbon content, high lubricity, and Biodiesel is biodegradable and non-toxic and has a low carbon content, high lubricity, and higher ash point than diesel. The purpose of this study was to obtain data on the physicochemical properties of biodiesel from waste cooking oil (WCO) produced with different amounts of catalyst in the transesterification process. Methods This research carried out a two-step process: (1) esterification with an acid catalyst (H2SO4) and (2) transesterification with an alkali catalyst (KOH). The remaining frying oil is degummed by adding 2% H3PO4. Furthermore, the esterification process was carried out by adding 2% (v/v) H2SO4 at 800 rpm for 90 minutes. The transesterification process using an alkaline catalyst (KOH) was varied from 0.7-1.5% at a temperature of 60 oC with a rotation of 800 rpm and a time of 90 minutes. In the ester/transesterification process, the ratio of methanol: oil is 1:2 (v/v). The biofuels are then tested for cetane number, flash point, density, viscosity, calorific value, and others. The results showed that the amount of wet catalyst (KOH) in the transesterification process gave a difference in the yield of WCO oil. The optimum value was obtained at the amount of 1% KOH catalyst, which was 85%.

Abstract

Biodiesel is a potential energy source that has attracted attention recently because it can be produced from renewable energy sources and produces low pollutants. Biodiesel is produced by transesterifying edible or non-edible vegetable oils using a catalyst. Homogeneous catalytic processes have disadvantages, such as the catalyst residue cannot be reused. Therefore, heterogeneous or solid catalysts are used, which can be easily separated from the reaction mixture by filtration and reused. A waste cockle shell can be used as a green base catalyst to synthesize waste cooking oil into methyl ester (WCME). The free fatty acid content of used cooking oil (2.19% wt.) was initially reduced to 0.11% wt., using a methanol-oil ratio of 6:1, waste cockle shell 2% wt., reaction time 60 minutes and temperature 60 oC. The effectiveness of the developed waste cockle shell contains high CaO. The results of this study indicated the potential of clam waste cockle shells and used cooking oil as a source of raw materials available in the community for biodiesel production.

Abstract

Biodiesel is one of the renewable energy sources, non-fossil. The chosen feedstock should ideally be low-cost. Using waste cooking oil can reduce synthetic biodiesel's price by up to 70%. However, biodiesel has the advantage of lower heating value and higher density, causing increased fuel consumption and NOx emissions. Biodiesel has physicochemical properties such as a more significant cetane number than fossil diesel, a high flash point, and the absence of sulfur. This study identifies the potential availability of WCO as biodiesel and summarizes recent studies on the physiochemical properties of WCO biodiesel. This study also aims to clarify the use of WCO biodiesel on engine performance and exhaust emission characteristics (H.C., CO, CO2, NOx) when this biodiesel is used. Engine type and biodiesel ratio were identified for all articles. This study also discusses the effect of adding nanoparticles on engine performance and exhaust emissions in WCO biodiesel. This study also clarifies material compatibility (corrosion, wear, and friction). The corrosion rate in various types of materials and corrosion testing methods. Finally, this paper presents the opportunity for WCO biodiesel to be very feasible to reduce fossil diesel use.
