The effect of harvest time on the moisture content and heating value of biofuels

Abstract

Results of laboratory tests on moisture content and heating value changes of 9 samples of biofuels (Jerusalem artichoke (stems), Miscanthus, triticale, hemp (male and female stems), flax (stems), saflor (stems), grass, hyso I and II (stems)) in relation with harvest time are presented. Stems of flax showed the highest heating value (17.2 MJ/kg), Miscanthus and stems of Jerusalem artichoke showed 15.5 MJ/kg. The lower heating value was about 12.5 MJ/kg (triticale, male stems of hemp and grass) and female stems of hemp showed the lowest heating value 8.1 MJ/kg.
