Descripción
Five equilibrium fluidized catalytic cracking (FCC) catalysts of different types, with unit-cell sizes in the range of 24.23-24.29 Å, were evaluated in the conversion of three commercial vacuum gas oil (VGO) feedstocks in a CREC Riser Simulator laboratory reactor at temperatures of 500 and 550°C, a catalyst-to-oil ratio of 6.1, and reaction times in the range of 3-30 s. The results have allowed us to define the main characteristics of the catalysts, in terms of various indexes, such as activity, gasoline yield and quality, and individual yields (using isobutane as a case example). In all cases, isobutane was essentially a primary product. It was observed that the yield of isobutane was linked to the hydrogen transfer properties and the activity of the catalysts. For a given catalyst, the higher the temperature, the less isobutane is formed at the same conversion, because of the lower incidence of hydrogen transfer reactions. The type of feedstock influences the isobutane yields, particularly on low-activity, low-hydrogen-transfer catalysts. The approach is shown to be a proper tool to evaluate commercial FCC catalysts (in this case, in the search for the optimum isobutane yield) and demonstrate that knowledge of the integral evaluations (feedstock, catalyst, and process conditions) is necessary.
