“…Tang and Neil, Kung, Kung and Kalelkar, Lee et al, Kansa et al, and Bennini et al reported pyrolytic endotherms, whereas Bamford et al, Akita, Roberts and Clough, Tinney, and Roberts 165 observed exotherms. Recognizing the unresolved nature of the heat of reaction, some recent workers utilized variable or multiple values for the heat of reaction according to the situation. − …”

In this review, we summarize the knowledge of the production and properties of charcoal that has been accumulated over the past 38 millenia. The manipulation of pressure, moisture content, and gas flow enables biomass carbonization with fixed-carbon yields that approachor attainthe theoretical limit after reaction times of a few tens of minutes. Much of the heat needed to carbonize the feed is released by vigorous, exothermic secondary reactions that reduce the formation of unwanted tars by augmenting the charcoal yield in a well-designed carbonizer. As a renewable fuel, charcoal has many attractive features: it contains virtually no sulfur or mercury and is low in nitrogen and ash; it is highly reactive yet easy to store and handle. Carbonized charcoal can be a good adsorbent with a large surface area and a semimetal with an electrical resistivity comparable to that of graphite. Recent advances in knowledge about the production and properties of charcoal presage its expanded use as a renewable fuel, reductant, adsorbent, and soil amendment.

“…Clearly the transport limitations need to be understood in the context of the severe conditions prevailing within the Fast-TGA system. As pointed out by several other researchers (Broido, 1976;Chan et al, 1985), the rate of solid-phase decomposition could be affected by these limitations.…”

The instrumentation and methods required to study rapid, radiative decomposition of highly reactive biopolymers are described and used to determine the kinetic parameters for the pyrolysis of Avicel PH105 microcrystalline cellulose. Experiments were carried out at heating rates greater than 2 K/s in a specially fabricated thermogravimetric analyzer system which employed a 30-kWe/2-kWth downward-facing beam, arc-image furnace as a heat source. The thermogravimetric data were interpreted assuming a simple, single-step reaction mechanism and using a nonlinear least-squares kinetic analysis. Based on the results, an apparent activation energy of 100.5 ± 3 kJ/mol, a preexponential factor of In [A (s'1)] = 14 ± 0.5, and nearly a first-order ( = 0.9 ± 0.05) reaction were obtained. The extent of char formation was determined experimentally and found to be in the range 6.6-8.4% by weight of original dry material depending upon the prevailing reaction conditions.
