How to Control Tar Content in Fixed-Bed Gasification? A Multi-Scale Approach

A. Anca Couce, N. Zobel & F. Behrendt
Nowadays no control of the tar content in a fixed­bed gasification process applying model predictive control (MPC) is possible because, firstly, the tar content can not be measured online, secondly, no model exists which is able to predict the tar content in adequate accuracy and, thirdly, no experimental data are available to validate such a model in adequate detail. This work deals with the approach followed in EVUR­TUB to overcome the current difficulties and develop...
