The synthesis and characterization of aluminum loaded SBA-type materials as catalyst for polypropylene degradation reaction
Obali, Zeynep; Sezgi, Naime Aslı; Doğu, Timur (2011-12-01)
The performance of pure and aluminum containing SBA-type catalysts prepared using different aluminum sources and different Al/Si ratios were investigated in the polypropylene degradation reaction using a thermogravimetric analyzer. For the synthesis of catalysts, aluminum isopropoxide and aluminum sulphate were used as the aluminum sources. Synthesized materials had high surface areas and exhibited nitrogen adsorption isotherms of type IV. EDS results showed that the aluminum incorporation into the structur...
The Thermal Characterization of Crude Oils in a Limestone Matrix of Different Particle Size
Kök, Mustafa Verşan (2014-05-03)
In the first part of this research, the effect of particle size (35-100 mesh) on the calcination kinetics of a limestone sample was investigated by thermogravimetric analysis technique. Thermal studies showed that two main weight loss regions are observed in limestone samples of different particle size. In the second part of the research, thermal analysis of a medium crude oil sample in a limestone matrix of different particle size is analyzed. Two different reaction regions were observed known as low tempe...

A previously developed and tested mathematical model for the simulation of both the bed and freeboard of atmospheric fluidised-bed combustors (AFBCs) burning high- and low-quality coals was modified to incorporate calcination of limestone and subsequent sulphation taking place in the emulsion phase, in accordance with a deactivation model similar to those for catalysts. The new model was then used to investigate the effect of excess air and Ca:S molar ratio on the behaviour of a pilot-scale AFBC, for which ...
