Abstract
The aim of this work was to determine the extent to which soot is formed and if there are any ways of reducing the formation of soot. In order to determine if soot formation will be a critical issue for the reverse flow reforming process modeling of the process was undertaken. The reformer was modeled using a detailed reaction mechanism to describe the kinetics of soot formation.The results of the simulations show that soot will be formed under the modeled conditions. Almost 10 % of the ingoing carbon will be converted to soot. It is worth noting that the tars present in the gasification producer gas account for more than 5 % of the ingoing carbon. The soot formation can be reduced with more than 20 % by using a simple thermal pre-reformer... (More)

The soot formation can be reduced with more than 20 % by using a simple thermal pre-reformer where higher hydrocarbons (C2 and higher) and some of the tars are reformed. By using a low temperature reverse flow reformer as a pre-reformer the soot formation can be reduced by nearly 30 % making it a highly effective alternative. A catalytic pre-reformer will most likely produce better results because of the lower temperature needed for reforming the higher hydrocarbons as compared to methane (Less)
