OSTI ID:5274251
This report focuses on the results of a series of experiments from two smallbatch pyrolysis reactors, using a New Mexico subbituminous coal. The objective of the research to be reported on here was to develop mass balances for the pyrolysis of coal in two small reactors, a batch reactor and a fluidized bed reactor. Detailed tasks are listed below: (1) To design and construct a bench scale batch reactor to study the devolatilization of coals at thermal equilibrium, i.e., at long residence times at a given temperature; (2)To design and construct a bench scale fluidized bed reactor to study the devolatilization of coals at thermal equilibrium; (3) To separate the pyrolysis products, the tars, water, char, and gases, for selective analyses; (4) To determine quantitatively the amount of total volatile matter (tar, water, and gases), released during pyrolysis of the coal as a function of temperature in both the batch reactor and the fluidized bed reactor; (5) to analyze for the composition of the char (solid residue) from the pyrolysis of coal as a function of temperature for both the batch reactor and the fluidized bed reactor; (6) To analyze for the composition of the tar from the pyrolysis of coal as a function of temperature for both the batch reactor and the fluidized bed reactor; (7) To identify gas species and to analyze for each species as a function of temperature in both the batch reactor and the fluidized bed reactor; (8) To compare the pyrolysis products of the batch reactor to the pyrolysis products of the fluidized bed reactor as a function of reactor temperature; and (9) To compare the experimental results of the batch reactor and the fluidized bed reactor to the results obtained by other researchers.
