Design and development of a rotating heater pyrolysis reactor

Abstract

Biochar is a valuable product of pyrolysis. A new rotating heater pyrolysis reactor (RHP) was developed to process a variety of biomass feedstocks of up to 30 L and produce biochar batches of several kilograms. The RHP design was simple, allowing for easy construction, low-cost operation, and low energy consumption. Biochar produced from softwood woodchip biomass in the RHP for 2-3 h was determined to have physical and chemical properties comparable to biochar produced from a conventional batch pyrolysis reactor at temperatures between 375-425 C.
