Study of deodorization by fluidized bed reactor No.1

Abstract

The burning deodorization by a fluidized bed reactor was studied principally as a way of controlling the oder pollution.
Trimethylamine and mercaptan were used as the test pollutants.
The offensive oder gas was come in contact with fluidized particles in the fluidized bed with 51 mm diameter from 300°C to 700°C with an apparent contact time between 0.1 and 0.5 sec.
To attain above 98% removal ratio of oder component, the bed temperature must be over 390°C with the 0.5 sec apparent contact time and 460°C with 0.1 sec for trimethylamine, over 460°C with 0.5 sec and over 580°C with 0.1 sec for mercaptan.
The materials concerned might be oxygenated incompletely under some conditions and in some cases oxides might discharge more offensive odor than the original
