    Additional experiments where stage combustion was used, secondary air injection into the freeboard, apparently also shows that with better mixing there is improved use of the CO and subsequent reductions in NO emissions, see Figure lUU a 90 - m.

    Read text version After analyzing model in different temperature, the optimum temperature for catalyst pellet was found around k. At high temperature T > the selectivity as well as yield of C2 at the pellet exit increased, while above this optimal temperature these values decreased.

The kinetics modeling of pyrolysis, oxidation of volatiles and CO, carbon reactions, heterogeneous and homogeneous ignition and combustion of carbon and coal are reviewed. Because of strong analogy of the group ignition and combustion to porous char ignition and combustion, the literature on porous char combustion is also included.

To allow completion of the reaction, the regenerator is operated with a slight deficiency of com- bustion air to provide CO in the upper part of the fluidized bed which then reacts with S02 via 2 CO + S02 = 1/2 S2 + 2 C02, (4) thereby decreasing the S02 partial pressure to about 70$ of the equilibrium value in reaction (3).

It was shown very clearly by Henrik Svensmark of Denmark. He did experiments on the theory and has written a very good book about it, called The Chilling Stars () and there is a film, The Cloud Mystery.

The book shows very clearly that there is a scientifically validated link between Solar activity and climate, which is being researched now.
