Abstract

The purpose of the present work is to assess the feasibility of scaling up of thermal treatment of tar conversion in a microwave reactor to improve the quality of the producer gas for power generation. The scale up process was analyzed based on microwave heating capacity and energy balance of material. The scale up analysis was conducted to obtain reactor performance with a capacity of 3.37 Nm3/h of producer gas based on the obtained experimental results in a small scale microwave reactor of 0.337 Nm3/h. The chemical and sensible energy contents of the input and output streams were considered for energy balance calculation. Energy supply from microwave power for heating process and heat losses from the wall of microwave reactor to the environment were also included. The results showed that the energy balance closure of the small scale microwave reactor was 75% only on average. In the mean time, scaling up analysis of the bigger reactor has better performance with average energy balance closure of more than 91%, showing that thermal treatment of tar process in a microwave reactor is very promising to enhance producer gas quality at relatively higher capacity.
