“…The above fact is due to the high ambient density of air, which creates strong air resistance to develop the spray. That's why mounting injection pressure has fewer impacts on tip penetration growth 11 . It is also investigated that spray tip penetration of diesel is either equal to or longer than B25 at all injection pressure.…”

“…Mohan et al 10 did an investigation on spray characteristics of WCO under high injection and ambient pressure using constant volume chamber and found that B100 incorporated higher spray tip penetration and velocity with narrow spray cone angle due to higher viscosity and momentum of fuel. Similarly, Bhikuning et al 11 conducted experiments on spray characteristics of WCO, bio hydro fined diesel (BHD) oil, and n-tridecane in constant volume chamber under evaporating and nonevaporating conditions and concluded that spray tip penetration of WCO was higher than BHD oil and n-tridecane under both conditions due to high-rheological property. Similar studies were also done by researchers 12,13 and found that biodiesel exhibited longer penetration and larger sauter mean diameter (SMD) than diesel and there was reduction in spray tip penetration with the increase in ambient pressure, while increases linearly as injection pressure raises at primary breakup stage.…”

Atomization characteristics and evaporation have major role in air‐fuel mixing and the combustion process in diesel engine. The aim of this study is to perform numerical and experimental analysis to investigate the spray pattern of biodiesel (waste cooking oil) generated from pressure swirl atomizer. The computation exhibits Eularian‐Lagrangian method to comprise flow of multiphase and also linearized instability sheet atomization (LISA) model to envisage atomization, sheet breakup, and film formation. The model's strength is the identification structure of spray created from pressure swirl atomizer. A three‐dimensional computational fluid dynamics work consisting of LISA and Taylor analogy breakup model are certified via experimentation taken from constant volume chamber. Further, spray tip penetration, cone angle, and sauter mean diameter (SMD) are identified for fuel (B100, B25, and D) under injection pressure of 110 and 160 MPa, and 2.8 MPa ambient pressure using swirl atomizer in constant volume chamber. This particular spray is quite important for application in diesel engines but is not extensively explored. The results reveal that as injection pressure increases from 110 MPa to 160 MPa. The spray tip penetration for B100, B25, and D are increased by 19.86%, 14.90%, and 14.50% respectively, further, cone angle at the start of injection decreases by 6%, 5%, and 3.41%, similarly, the average SMD decreases by 25%, 33.33%, and 25.4%, respectively. This is due to the rheological property of fuel, turbulent energy of droplet and air is maximum in primary breakup zone.

“…Between these biofuels, one that has received a lot of attention is the replacement for traditional jet fuel, recognized as renewable biojet fuel . Biojet fuel typically has a positive influence on sustainability, whereas traditional flying fuel affects the atmosphere through a multiplicity of emissions such as NO x , SO x , and CO 2 ; this leads to a change in climate and ozone layer reduction . Biojet fuel can replace conventional jet fuel without requiring changes to the design of existing aircraft engines or fuel distribution systems .…”

The use of waste oils as pyrolysis feedstocks to manufacture high-grade biofuels has prompted researchers to focus on developing renewable energy to overcome the depletion of fossil fuel supplies and the global warming phenomena. Because of their high hydrogen and volatile matter concentration, waste oils are ideal raw materials for the production of biofuels. It is challenging to attain satisfactory results with conventional methods, such as transesterification, gasification, solvent extraction, and hydrotreating due to flaws such as high energy demand, long time, and high operating costs. Catalytic pyrolysis of waste edible oils was employed as a resource for the generation of biodiesel. The application of the catalytic cracking process has the potential to alleviate the existing situation. In this study of catalytic cracking conversion of waste cooking oil to produce different biofuels, grades were investigated using two heterogeneous catalysts. The catalysts were activated montmorillonite (PAMMT) clay and its modified form using a chitosan biopolymer (PAMMT-CH) nanocomposite. The catalysts were identified using infrared spectroscopy, X-ray diffraction patterns, transmittance electron microscopy images, surface area, and thermal stability. The catalysts were tested for their performances using different amounts (0.1–1% by weight) at a temperature assortment of 200–400 °C during a time range of 60–300 min. The experimental studies were carried out in a batch reactor. GC mass spectra were used to investigate the catalytic cracking products. Fractional distillation is used to separate the final products from various reaction conditions. The physicochemical properties of resulting biofuels were profiled by quantifying their densities, viscosities, specific gravities, pour points, flash and fire points, cetane numbers, carbon and ash residues, and sulfur contents. The optimum conditions of the yield product were 300 and 400 °C, catalyst weights of 0.7 and 0.8% w/v, and reaction times of 120 and 180 min concerning the (PAMMT) and (PAMMT-CH) nanocomposite, respectively. The determined properties were located within the limits of the specific standards of ASTM specifications. As a result, the PAMMT nanocomposite produced biofuel comparable to biodiesel according to ASTM specifications, while the PAMMT-CH nanocomposite produced biofuel comparable to biojet.

“…[6] The cost of raw materials accounts for 80% of the total cost of biodiesel production. [7] Biofuels are produced through the crack formation of various plant oils, including Alcea pale oil [8]. Oils of wood [9,10], Soy proteins [10], palm kernel oil [11], textile canola oil [12], Seed oil [13], and disposal oils [14] are all examples of plant oils.…”

There is no doubt that petroleum is essential to our way of life. It is known that petroleum is a nonrenewable source of vitality since petroleum generation all over the globe will not exceed 30 years, and as a result, oil will run out some day in the future., thus it may be necessary to find out other sources of vitality to advance with ease. Investigators are now seeking contemporary alternatives to fossil fuel. Biofuels are considered the most environmentally safe fillers that may be employed. In this study, Egyptian Oil -induced and Safflower oils were obtained and converted into their contrasting biofuels using catalytic breaking with catalysts that are diversified (Alumina and Montmorillonite -HCl) in varying proportions (0.2 percent, 0.4 percent, 0.6 percent, 0.8 percent & 1 percent). The following biofuel generation circumstances were investigated: catalyst type, catalyst proportion (percent), change time, and temperature. The obtained items' findings were equivalent to The United States Society for Quality (ASTM) standards.Keywords: Catalytic going to crack; biofuels; seed oil; almond oil; fuel properties. INTRODUCTIONCrude oil is a substance recognized to be the source of fuels, lubricants, heat and power generation sources, and raw materials in the petrochemical industry. It is also recognized that petroleum-derived fuels have a negative impact on the environment; biofuels are thought to be the most environmentally friendly fuels available. A sustainable alternative fuel that has no harmful ecological, financial, or cultural consequences.Sustainable biofuels should not compete with food or freshwater resources, nor should they contribute to deforestation, while also providing socioeconomic value to local communities where plant stocks are grown. Jatropha and castor oil are two oil-based energy crops that can meet these sustainability criteria. The use derived from oil extracted from seeds is favorable because it is a non-edible oil that will not compete with food crops. Biodiesel, as opposed to conventional petroleum diesel, is a clean energy source. The commercialization of
