Abstract
The purpose of the gas cleaning project is to define the necessary parameters in order to implement decentral, straw-fueled combined heat/power plants with gas cleaning, based on tar cracking.Four catalyst systems for tar decomposition into gaseous components have been tested according to a new gas cleaning method. The catalysts have been tested in temperature interval 350 - 600 deg.C. The cleaning process was carried out under atmospheric pressure. The composition of gas to be cleaned simulated the typical gasification product of straw/air mixture: 12 % hydrogen, 12% carbon oxide, 16 % carbon dioxide, 20 % water vapor, 40 % nitrogen, and 0.03 % hydrogen sulfide. Phenol was added to water in concentration corresponding to 10 g/Nm{sup 3} wet synthesis gas, as this tar component is the most difficult to convert. The catalysts tested were: nickel-molybdenum on alumina, nickel-tungsten on alumina, nickel-tungsten on silica-alumina and palladium on alumina support. Characteristics of these catalysts in form of graphs and numerical values are given. (EG)
