The mechanisms of chemical kinetics of the Reburning process using pyrolysis gases as a reburn fuel are determined. It has been shown that CO, CO2, H2 have very little effect on the reduction of the nitrogen oxides under conditions characteristic for the coal combustion, and hydrocarbons play the major contribution to the reduction of the nitrogen oxides. The results of the test calculations showed that the process of the nitrogen oxides reduction by the biomass pyrolysis products can be calculated by a simplified mechanism of the chemical kinetics of the Reburning process by replacing hydrocarbons with one substance (with a close carbon/hydrogen ratio as in the real pyrolysis gas mixture), provided that the mass fraction of carbon is preserved, fed to the reduction of nitrogen oxides unchanged. This approach significantly reduces machine time and calculates the nitrogen oxides reducing efficiency by Reburning technology with an accuracy of 17%.

Cashew Nut Shell

Chemical kinetics research antibacterial of aliphatic alkane fraction from the results of pyrolysis Cashew Nut Shell (CNS) (Annacardium occidentale L.) on Eschericia coli have been carried out. Cashew nuts are prepared by separating the shell and seeds for pyrolysis and purifying using a fractional distillation device. The results of E. coli anti-bacterial activity test from aliphatic alkane fractional distillation results of cashew nut shell pyrolysis products showed that the inhibitory power was different from each concentration variation of 100%, 75%, 50%, 25%, and 12.5%, with inhibitor zone: 8.02; 7.16; 5.56; 4.52 dan 4.26 mm which indicates that the inhibition is weak category for 12.5% and 25%, medium category for 50%, 75% and 100%. The clear zone that has been formed are calculated in terms of its chemical kinetics including the reaction order and the activity rate constant. The reaction order (n) antibacterial of aliphatic alkane fraction from the results of pyrolysis CNS on E. coli was 0.3145 with a constant activity rate of (k) = 1,7791.

Research on application and kinetics study of fractionation pyrolysis product from cashew nut shell as antifungal of Candida albicans has been carried out. This study aims to determine the constituent compounds, antifungal activity and chemical kinetics including order and rate constants antifungal activity C. albicans from fractional distillation results of cashew nut shell pyrolysis products. Cashew nuts were hydrolyzed and purified using a fractional distillation device. The results of the antifungal activity test C. albicans from fractional distillation results of cashew nut shell pyrolysis products showed that the inhibitory power varied from each concentration variation of 12.5%, 25%, 50%, 75%, and 100%. The concentration of 100% was the highest inhibitory characterized by the formation of a clear zone of 18.23 mm which indicates that the inhibitory force is a strong category. The clear zone that has been formed was calculated in terms of its chemical kinetics including the reaction order and the activity rate constant. The reaction order of antifungals C. albicans from the results of fractional distillation of cashew nut shell pyrolysis products is 0.15 with a constant activity rate of 8.74.
