Abstract: The paper compares the results of the test of continuous moisture content measurements of lime hydrate under operating unit production conditions where the infra-red spectroscopy method and the classical method of the mass-decrease of samples in drying chamber were employed. The large differences which two measurement systems show are explained in connection of the changes of the measurement process conditions. The paper shows the taken data of infrared spectral measurement of the powder material moisture content as the function of:

Abstract: The depletion of fossil fuel is creating awareness of the need for a sustainable future, and interest in alternative energy sources has increased tremendously in recent years. Pyrolysis is one of the efficient thermo-chemical method of harnessing energy from biomass. The aim of this work was to conduct an experimental study on the pyrolysis of pineapple (Ananas comosus (L.) Merr.) peel with the emphasis on the characterisation of the peels and their chars. Pineapple peel was pyrolysed in a horizontal tubular reactor under inert atmosphere. The effects of pyrolysis temperatures, heating rates and residence time on the yield of the bio-char were investigated. Pyrolysis runs were performed at temperatures between 300 and 700 0C with heating rates of 5 and 50 0C min-1. The residence time was between 0 to 3 hours. The obtained bio-char ranged between 29.3 and 47.1 %wt, at different pyrolysis conditions. The optimum bio-char yield was obtained at 425 0C with a heating rate of 5 0C min-1 and
