“…Similarly, devolatilization at elevated pressures retards the escape of these reactive species, thereby increasing internal concentrations and thus the rate of secondary reactions. Belt et al (1971) discovered that highest yields of char were obtained from their entrained flow carbonizer at highest inert gas pressures. A similar pressure effect on yield from Pittsburgh Seam bituminous coal was reported by Anthony et al (1975).…”

A laminar flow isothermal furnace has been constructed and used to study lignite pyrolysis in nitrogen at temperatures between 700 and l000°C. Particles of a Texas lignite (Darco Seam) between 41 and 201-microns in mean diameter, are found to flow down•the furnace tube with velocities approximated by the summation of the gas plugflow velocity and particle free-fall velocities. Some particle shrinkage and density changes occur during pyrolysis. Pyrolysis rate
