Pyrolysis characteristics

The solutions obtained by Rosen show that at low pressures, the burning rate becomes linear in pressure and the surface pyrolysis characteristics are not important. At high pressures, however, the burning rate becomes independent of pressure and is determined almost entirely by the decomposition reactions at the solid surface. Rosen points out that this simple model can...

The fact that the freshly created hydroaromatic structure in reduced coals contributes little to the formation of gases (except for some unsaturates, Table V) is perhaps also evident from the correlation shown earlier between the yield of extra tar and the extra hydroaromatic carbon created by reduction (12). These results are recast in Figure 3 to show more effectively the pyrolysis characteristics of reduced coals and hence throw light on the formation of gases.

ABSTRACT The radiative pyrolysis of wood (thick cylinders and chip beds) has been investigated experimentally for external radiative heat fluxes in the range 28-80kW/m, resulting in maximum sample temperatures of 600-950K. Radial temperature profiles, product yields and composition, and devolatilization rates have been measured. The influences of wood variety (hardwoods and softwoods) on the pyrolysis characteristics are discussed and comparisons are made with biomass (agricultural residues). 

The influence of wood variety (beech, chestnut, Douglas fir, redwood and pine) on the conventional pyrolysis characteristics has been investigated for a wide range of applied radiation intensities (front 28 to SOkW/m ), which correspond to final sample temperatures of 600-950K. 

An improved understanding of the quantity and quality of more complex pyrolysis products of organic matter can be obtained by first examining the relatively simpler pyrolysis characteristics of the major types of biomacromolecules polysaccharides, lignin, nucleic acids, proteins, and lipids (Figure 8.2).
