Abstract:
The higher heating value (HHV) is an important parameter to evaluate fuels from biomass and wastes. In literature, there are a large number of formulas to calculate the HHV from the weight fractions of the elements for various substances. The measured HHV of 50 samples from cracked vegetable oil (CVO), hydrotreated cracked vegetable oil (HCVO), diesel and vegetable oil have been compared with the calculated values from the elemental composition. The oxygen content of the samples varies from 10.7 wt.-% for the raw material rapeseed oil to 0.09 wt.-% for pure diesel fuel. The best accordance of the compared formulas shows Boie’s equation [1] (general) HO[MJ/kg] = +0.3483*wC[%] +1.1591*wH[%] -0.1080*wO[%] +0.0628*wN[%] +0.1047*wS[%] with an average relative error of 0.5 %.
