In PCT publication no. WO2007097600 a direct heated rotary kiln is used as the activation reactor. With the direct heated rotary kiln the rotary drum of the indirect heated rotary kiln can be made from concrete instead of metals including steel stainless steel etc. which can solve the problem introduced by high activation temperature.

The Concept Design And Performance Of A Novel Rotary Kiln

The gasifier is a rotary kiln with a 6 degree angle of inclination. Unlike a traditional rotary kiln it is divided into three regions which are oxidative degradation partial oxidation and char gasification. Biomass is fed into the reactor from the left end and passes through the gasifier by rotating the reactor.
