摘要：
In this study, three feedstocks were studied (Grape marc, Kenaf stems, flax shive) for biochar production. The pyrolysis operation was carried out at 400; 500 and 600 degrees C and a constant heating gradient rate of 5 degrees C/min for a future potential use in agriculture. The experimental results showed that the biochar yields decreased with the increase of the applied pyrolysis temperature and were approximately constant above 500 degrees C for all feedstock. The physico-chemical properties of grape marc and Kenaf indicated that they have the highest amount of potentially available minerals with an interesting value of surface area and microposity. These properties make these biochars suitable candidates for soil amendments as well as pollutants removal from aqueous and gaseous effluents.
