Kovar Tube as a Potential Catalyst for Conversion of Tar Produced from Biomass Gasification

A pre-oxidized Kovar tube was employed as a reforming catalyst for the conversion of naphthalene. Under dry reforming condition, 24.7 % naphthalene conversion could be achieved, whereas 36.6 and 42.3 % naphthalene conversion could be achieved when steam was added to the producer gas at the volume ratio of 0.06 and 0.11, respectively. Increasing the reforming tempe- rature to 1173 K enhanced the catalytic removal of naphthalene to 91.5 %.

FINDING OF KINETIC CHARACTERISTICS OF THE PROCESS CO-GASIFICATION OF HEAVY COAL TARS WITH LIGNITE AND WALNUT SHELL

Studied of co-gasification of heavy coal tars with lignite and walnut shell in the temperature ranged from  400 to 500 °С, the flow rate of oxidand (air) ranged from 0,0005 to  0,004 m3/min.  It is established that the weigth loss of the sample mixtures in the gasification process has a S-shaped. Mathematical and graphical dependences of the influence of oxidant flow rate on the values of reaction rate constants and activation energy of gasification of experimental mixtures were developed.
