The conversion of peats : 1-Complex chemical equilibria of the pyrolysis of peat 2- High pressure hydrogenation of humid acids
The work presented in this report was designed to complement studies conducted at the University of Sherbrooke on the catalytic hydrogenation of peat to liquid fuels. Firstly, a literature survey was completed on the hydrogenation of organic wastes, peat and humic acids, which constitute over 50% of the dry weight of peat. Past studies in this field indicated that organic materials can be completed converted to gaseous, liquid and solid fuels, and that liquid fuel yields can approach 50% of the weight of the original material. The liquid produced was generally a soft bitumen-like substance having a calorific value of approximately 17000 BTU/lb (40 kJ/g). Two studies related to the conversion of peat were subsequently conducted: a) a fundamental thermodynamic analysis of the ideal pyrolysis of peat ·at different operating conditions to gain insight into the composition of the products of pyrolysis; and b) experimental research on the liquefaction of humic acids to determine the role of humic acids in peat conversion and to obtain fundamental information on the mechanism of peat liquefaction.
