“…At low loads, the injected fuel may hit the walls of the relatively cool combustion chamber which reduces the fuel–air mixing rate, resulting in incomplete combustion, whereas, at high loads, the mixture is relatively rich; therefore, the carbon molecules may not find enough oxygen to be completely converted into carbon dioxide. 38 The CO emissions at full load for diesel, H10D90, H20D80, H30D70, H40D60, H50D50 and H100 is 31.9, 29.7, 27.9, 26.55, 27.41, 30.7 and 34 g/kW h, respectively. The trend of CO emissions is similar to HC emissions, that is, it decreases for the blends and the lowest emission is observed with H30D70.…”

Biomass-based fuels are gaining importance for operating a compression ignition engine as they can curb greenhouse gases and are a key for addressing the energy security. Hydrotreated oil is considered to be a potential drop-in fuel for the compression ignition engine as its cetane number is higher than fossil diesel. In this study, hydrotreated waste cooking oil and its blends (10%, 20%, 30%, 40% and 50% by volume) with diesel were prepared. The ignition probability of the test fuel samples was found using a hot-plate test setup. The neat hydrotreated fuel has higher ignition probability at a particular temperature than the other test fuels. The Sauter mean diameter of the test fuels was also observed using a Malvern Spraytec test setup. The results reveal that the neat hydrotreated fuel has higher Sauter mean diameter due to its high viscosity. As the percentage of the hydrotreated fuel in the blend decreases, the Sauter mean diameter decreases and diesel has the lowest Sauter mean diameter. The test fuels were also used to run a compression ignition engine. The results reveal a decrease in brake thermal efficiency with the increase in the hydrotreated fuel share in the blend. The heat release for the blends starts earlier than diesel and the peak heat release is also lower than diesel. The HC, CO and smoke emissions for the test blends decreases up to 30% blend. When the percentage of the hydrotreated oil is further increased, the emissions starts increasing. The NO emissions were lower than diesel for all the test samples. As compared to diesel, the maximum reduction in NO (neat), HC (30% blend), CO (30% blend) and smoke emissions (30% blend) is 23.2%, 14.4%, 13.83% and 13.3%, respectively.

“…Any fuel in which the amount of carbon absorbed by the biomass used for its production during the photosynthesis stage of the bio-based feedstock exceeds the emission associated with the use of the fuel is referred to as carbon negative (Matthews, 2008). Other examples of biofuel include biogas as well as bio-alcohols like ethanol, methanol and butanol (Ashok et al, 2018). In compression ignition engine, the major properties used in determining the superiority of fuels are cetane index, boiling point, low poly aromatic content, low density, and viscosity (Ashok et al, 2018).…”

This study evaluates the performance and emission characteristics of an orange peel biodiesel blended with cashew nut shell liquid. It investigates the efficacy of cashew nut shell liquid in reducing nitrogen oxide (NOX) emissions resulting from the combustion of the biodiesel, while optimizing its performance.The biodiesel was prepared via transesterification. It was obtained by reacting orange peel oil produced through Soxhlet extraction with methanol in the presence of NaOH. The biodiesel was blended with cashew nut shell liquid in the ratio 70%:30% (B70).Experimental results demonstrate that blending cashew nut shell liquid with orange peel biodiesel causes a slight decrease in NOX emission. B70 generates 150 ppm of NOX, while B100 and diesel produce 159 ppm and 193 ppm, respectively. The hydrocarbon emission of B70 was 8% lower than that of B100 and 22.3% lower than that of diesel. As regards CO and CO2 emission, B70 performs better than B100 and diesel. The performance parameters were computed at brake powers of 2.5 kW, 5.0 kW, 7.5 kW, and 10 kW. In comparison to diesel and B100, B70 has higher brake thermal efficiency at all loads. The brake specific fuel consumption (BSFC) of B70 is higher than that of diesel, but less than that of B100 at 2.5 kW and 5.0 kW. At 7.5 kW and 10 kW, the BSFC of B70 is higher than that of B100 and diesel. Conclusively, B70 gives optimal performance and less emission. Hence, cashew nut shell liquid is a good additive.

“…Orange or sweet orange (Citrus sinensis L. Osbeck) is one of the 30 species of Citrus [1], and it is the most common cultivated fruit all over the world. It belongs to the Rutaceae family, being Brazil, the largest orange juice producer [2] in the world. An increase from 3.2 million metric tons in 2016/2017 to 50.2 million metric tons in 2020 is expected, mainly attributed to a substantial production in Brazil.…”

The development of efficient pretreatments is widely used in biobased products aiming to add value to the residue. In this study, orange bagasse is investigated for cellulose extraction under moderate chemical sequential extraction conditions. Three pretreatments are evaluated: alkaline treatment, organosolv, and residue insoluble alcohol. After, all pretreated samples are bleached. The results are analyzed by chemical composition, Fourier–transformed infrared spectroscopy, X-ray diffraction, and thermogravimetric analysis. In general, similar results are observed for all bleaching samples, independently of the pretreatment. It is observed a similar cellulose amount among the samples. When compared only to the pretreatments, alkaline shows to be a more effective way of presenting a higher crystallinity index. Hemicellulose and lignin are mostly removed after pretreatment. FTIR and XRD indicated that the pretreatment seems to be more effective in the first step. TG curves presented a more homogeneous pattern due to cellulose removal showing three steps for pre-treatment and two steps for bleached samples. The obtained cellulose has numerous potential applications, and a suitable route can be selected according to available reagents.
