The Effect of Off-Spec Canola Biodiesel Blending on Fuel Properties for Cold Weather Applications

Abstract

Biodiesel is a renewable and reduced-emission alternative fuel produced mainly from the alcoholysis of vegetable oils and/or animal fats. It is mainly used in blends with diesel fuel to reduce emissions, enhance lubrication and lower sulfur content. Being able to accurately determine the physicochemical properties of blended fuel is important for optimal injection, combustion, and lubricating performance in diesel engines. Also, fuel properties vary as the ratio of biodiesel-diesel changes, affecting the final fuel quality. In this study, a wide range and narrow intervals of (0,2,4,6,8,10,12,15,18,20, 25, 35, 50, 75 and 100% by volume) off-quality canola-based biodiesel blends were prepared at ambient conditions and used to study the blended fuel properties (density, kinematic viscosity, flash point, cloud point and pour point). This is particularly important for examining the effect of a biodiesel content of more than 20%-the industry maximum blend content-on cold flow properties, fuel stability, energy value, and emissions. It was found that the kinematic viscosity and density increased linearly as the concentration of the biodiesel in the blend increases. The pour point and cloud point temperature showed a small increase up to 35% blending ratio and a rapid increase in temperature for biodiesel concentrations higher than 35%. Also, the flash point remained almost constant at an average value of 73 • C for blends less than 20%, above which the values for the flash point increased exponentially with biodiesel concentration. Furthermore, predictive correlations were developed for all tested fuel properties from regressing corresponding experimental data. All models exhibited excellent agreement with experimental data with an average absolute deviation of less than 5%.

Experimental investigation of 4‐cylinder compression–ignition engine parameters fueled by newly formulated hydrous ethanol–diesel‐emulsified fuel infused with nano‐sized γ‐Al2O3 particles

“…34 However, the suggested emulsified fuel's higher cloud point could be a drawback limiting HEDA fuel usage in cold weather engine running circumstances. When biodiesel was combined with diesel, Hassan et al 35 showed similar outcomes.…”

Quality Characteristics of Biodiesel Produced from Used Cooking Oil in Southern Europe

“…The objective is to evaluate the quality characteristics of the produced biodiesel through the analysis of the samples, conducted at ELIN Biofuels Laboratories. Determining the properties of the UCO based biodiesel is essential for the optimal injection and combustion performance of diesel engines [29]. Parameters were compared to the maximum and minimum permitted values, according to the Standard EN 14214: 2012 [30].…”

Canola meal‐derived activated biochar treated with NaOH and CO2 as an effective tool for Cd removal

“…17 Canola biodiesel is mainly used in diesel blending, reducing carbon emissions, improving lubrication and reducing sulfur content in fuel. 18 Some authors have already studied canola meal, reporting good results for the adsorption of methylene blue and other cationic dyes using low-cost biosorbents from canola wastes 19 or canola shells. 20 In addition, Al-Asheh and Duvnjak 21 conducted a pioneering study that showed the adsorption potential of canola biosorbents for copper removal from water sources.…”
