Water removal from biodiesel/diesel blends and jet fuel using natural resin as dehydration agent

Water removal from both biodiesel and diesel/biodiesel blends was studied using a natural removable additive, natural resin. Specifically, two different samples of biodiesel/diesel blends and one of JP8 fuel were studied before and after the blending process with the natural additive. As well as moisture concentration, the properties of density, kinematic viscosity, conductivity, flash point, and heat of combustion were also investigated. Using the proposed method of water removal improves the physicochemical properties of biodiesel/diesel fuel blends, increases the heat of combustion up to 361J/g, reduces the moisture by approximate to 66%, and reduces the conductivity down to 39.5%. In the case of JP8 fuel decreasing moisture content increases the heat of combustion by 187J/g, decreases the conductivity by 60%, and establishes the moisture level within accepted values, from 68 to lower than 50mg/kg.
