Effect of Blending on Cold Flow Properties of Biodiesel Produced from Waste Frying Oil

Abstract

Recycling waste frying oils is a significant environmental and economic issue. Biodiesel production from waste frying oil is an effective method to obtain a sustainable energy source. Waste frying oil is considered an essential source of biodiesel production. Biodiesel fuel made from fats or oils, such as waste frying oil with high levels of saturated fatty compounds, tends to have high cold flow properties (CFPs). Waste frying oil (WFO) was sourced from a cafeteria on Near East University's campus and underwent a transesterification reaction to produce biodiesel fuel. The cold flow properties of WFO based-biodiesel—CP (cloud point), PP (pour point), and CFPP (cold filter plugging point)—were measured at 15°C, 11°C, and 13°C, respectively, following current ASTM and EN standards. These temperatures were also assessed for blends of biodiesel and commercial diesel. Due to its cold flow characteristics, pure biodiesel can be effectively utilized from May to October in Lefkoşa. However, appropriate blends of biodiesel and commercial diesel can be formulated for use during the winter season.
