Effect of Citric Acid Addition on Transportation of Semi-Carbonized Fuel

Abstract

To clarify the optimum pyrolysis condition of the semi-carbonized fuel and the effect of citric acid addition on the transportation, experiments of the “semi-carbonization” pyrolysis were conducted for cellu-lose, citric acid and their mixtures. The acid additives promoted dehydration of cellulose, and affected the weight yield of char derived from cellulose within the temperature region of the semi-carbonization pyroly-sis. The transportation analysis model of the semi-carbonized fuel was presented to evaluate the optimum weight yield for a given transportation distance. It was found that the acid additives reduced the weight yield at a given pyrolysis temperature and contributed to improving the transportation of the semi-carbon-ized fuel.
