Translation Of Mat Kinetic Data To Model Industrial Catalytic Cracking Units, Rafael Maya-Yescas, Elizabeth León-Becerril, Daniel Salazar-Sotelo

Rafael Maya-Yescas

Bench and laboratory scale reactors are required to infer kinetic data for catalytic cracking units. One of the most common methods is the microactivity test (MAT, ASTM D-3902-92), that emulates the catalyst-to-oil ratio using a fixed-bed reactor and a semi-batch accumulator of liquids. Translation of data obtained from MAT tests in order to infer kinetic parameter to model continuous industrial units is, consequently, difficult and uncertain. In this work, the extraction of kinetic data obtained in a MAT reactor is analyzed. Estimation of a kinetic rate equation to evaluate instantaneous conversion in MAT reactors is performed. The activation energy obtained …
