Differences between maceral types with respect to heteroatom partitioning during pyrolysis under conditions representative of pf-combustion have been investigated. Pyrolysis experiments have been carried out in a wire-mesh reactor; maceral concentrates and whole coals have been heated at 5000 o C s -1 to 1500 o C, in atmospheric pressure He. The proportion of N-retention...
The pyrolytic behaviour of sets of maceral concentrates have been examined under conditions similar to those of pf-combustion. Relative combustion reactivities of chars prepared during the pyrolysis experiments have been compared by standard methods. As expected, for samples of similar elemental C-content, total volatile release decreased as: liptinite > vitrinite > inertinite. The data indicates...
The present study was undertaken to clarify the purpose of using reactive gases during the thermochemical processing of biomass. Conversions observed during pyrolysis (He) have been compared directly with gasification in H 2 , CO 2 and steam-helium mixtures. Experiments have been carried out at pressures between 1 and 20 bar, in a fixed-bed hot-rod reactor, operating at a relatively...
Changes in the combustion reactivity of sets of chars from five coals have been determined as a function of increasing devolatilisation temperature, heating rate and pressure. Chars were prepared in wire-mesh pyrolysis reactors, where evolving volatiles are rapidly removed from the vicinity of the heating coal. Samples were heated at rates between 1 and 5000 Ks -1 to temperatures up...
