Abstract:

The main objective of this work is investigation of catalytic tar destruction in order to evaluate two selected catalysts, namely dolomite, available in Lithuania as natural resource, and char derived from pyrolysis of used tires. The efficiency of these catalysts were investigated as an ability to decompose tar hydrocarbons at high temperatures and optimal process conditions were determined, which are base starting point for developing new functional technological solution. Results of catalytic steam reforming of real tars from biomass pyrolysis are presented in this article. Tar destruction was performed in a fixed bed reactor changing temperature from 700°C to 900°C and space­velocity from 0.28 to 0.04 s­1 with constant steam to carbon ratio of H2O/C=1 and initial concentration of tars 21.1±1.89 g/m3. It was determined that thermal destruction of tars is most intensive using waste tire char as a catalyst at 900°C and 0.04 s­1. At this condition complete conversion of tars was achieved. Results of the research were compared with result of other authors who used dolomite from various countries of origin and char from biomass pyrolysis for tar destruction.
