Full size image 20 illustrates the SARA procedure and shows a photograph of the fractions collected. Kinetic analysis The apparent activation energy changes with the extent of the reaction owing to the multi-step mechanism assumed by the oils during pyrolysis and combustion. The variation of apparent...
in batch crystallizers (Chew et al., 2007;Kee et al., 2009a,b). In these experiments, the supersaturation setpoint is chosen so that the solution concentration is kept above the solubility of the metastable form for the whole duration of the process. This way the dissolution of the ...

The results revealed that, on alumina the acid was irreversibly, non-dissociatively adsorbed in the form of hydrogen-bonded molecules, and dissociatively in the form of bidentate bound acetate species over the full range of temperature scanned. In the gas phase, no chemical change was observed....

The ultraviolet (UV) aging of bitumen involves a series of complex chemical reactions due to its complicated chemistry and structure. To conduct the UV aging on simplified components of bitumen is very helpful to reveal the UV aging mechanism accurately. In this study, two bitumens were separated...
