Abstract [en]

In the present study, a method was developed for testing of the tar adsorption capacity of a bed of granular activated carbon for the application of sampling particles from biomass gasification at high temperature. A laboratory scale gasifier was used to produce a tar-rich gas and sampling was performed using a dilution probe, diluting the gas with either pure nitrogen or nitrogen containing K2SO4 particles. It was found that when using pure nitrogen for dilution; particles were formed using all tested primary dilution ratios; however the concentration decreased when the primary dilution ratio increased. When using nitrogen containing K2SO4 particles for dilution the particle number and volume size distributions were identical with the reference when higher primary dilution ratios were used while particle formation took place when the primary dilution ratio was lower, indicating incomplete tar adsorption. The conclusion of the study was that the method could be used for testing of the tar adsorption capacity of a bed of granular activated carbon for the application of sampling particles from biomass gasification at high temperature and that it is advantageous to use nitrogen containing K2SO4 particles instead of pure nitrogen for dilution in order to facilitate theevaluation of results.
