Summary:Title screen
The low-temperature pyrolysis of wood briquets is investigated. A double-walled reactor permits indirect heat supply. In modeling the continuous production of semicoke from wood briquets, the process is divided into stages: preliminary heating (at 220°C, which corresponds to briquet production); low-temperature pyrolysis (temperature 350–550°C); and cooling of the semicoke in an inert medium (gaseous nitrogen). The process is exothermal. The release of H2, CH2, and CO (with maximum concentrations of 7.0, 47.6, and 31.2 vol %, respectively) is observed. These compounds are present in the hot gaseous products formed after condensation of the vapor–gas mixture. The characteristics of the semicoke produced are determined. The variability in its reactivity and morphological structure is investigated. With increase in carbonization of the semicoke samples, nonlinear increase in the calorific value is observed (from 30.04 to 33.02 MJ/kg). In addition, the morphology of the particles changes, on account of the formation of open pores and channels.
