<p>An improved batch process for the pyrolytic conversion of woody and herbaceous plant material is provided which yields charcoal, on a dry weight basis, in yields ranging from about 35 % to about 50 %, having volatile matter content of about 25 % or less, and fuel value of 13000 BTU/pound. The batch process can be conducted in two hours or less per batch with virtually instantaneous reloading for subsequent batches without substantial cooling of the reactor (10) utilized for the process and without exposing the hot processed charcoal to air or oxygen sufficient to cause combustion upon removal from the reactor (10). The reactor (10) is imbedded in insulation material (11). Carbonaceous material (13) is loaded into canister (14) and admitted into the reactor (10).</p> |
