Calorific values of rapeseed methyl ester (RME) and soybean methyl ester (SME) biodiesel blends have been determined by using of the high-precision combustion calorimeter. Temperature and pressure dependences of the calorific values in the range (273 to 373) K and (1 to 200) bar have been derived for the RME and SME biodiesel blends B100. Practical equations for calculating of the thermal correction for calorific values taking into account the composition, temperature, and pressure have been proposed.
