Abstract
Gasification of fuels derived from biomass is of interest in connection with combined cycle systems. During gasification tar compounds can be produced, and these can block further stages of the process. As gas turbines are very sensitive to tar compounds it is necessary to remove the tar completely from the gas. The most effective method appears to be catalytic cracking and it is suggested that dolomite is an effective and cheap catalysator. Based on a survey of relevant literature, the aim was to discover optimal conditions for the process of dolomite cracking. It is concluded that it is important to decarbonate the dolomite before use, that dolomite is not suitable for use in fluidized beds as it can become eroded and is subsequently very quickly blown out, and that it is important to hold the temperature at a level of ca. 800 deg. C. Conditions for fixed bed cracking both with and without steam are also desderibed. (AB) 15 refs.
