Because hydrotreating (HDT) of FCC gasoline is one of the important processes used to prepare such gasoline for blending, the development of a catalyst for this process is of great interest. Currently, the industrial HDT of FCC gasoline consists of two stages and the creation of a new catalyst for one-stage HDT will make this process more efficient. Recently, our group has developed the CoMo/Al2O3-ASA catalyst and studied the influence of Si/Al ratio on the target reactions of HDT process. Despite the high selectivity and activity, the catalyst with ASA is not applicable in industry because of its low strength. The present work moves forward to study the influence of the ASA content in the catalyst support and clarify the possibility to develop the catalyst that combines high activity and selectivity in HDT reactions with successful performance. Here we show that the CoMo catalyst with ASA/Al2O3 molar ratio 1/1 in the support is the best combination for FCC gasoline hydrotreatment due to exceptional properties of the catalyst composition.

A method is proposed for creating an optimal parametrically robust structure system of a state observer based on the process of similarity converting of a plant model, in which the conversion matrix is formed by varying singular numbers of controllability and observability gramians. The method enables a state observer structure to be obtained with a definite ratio of controllability and observability that permits fulfillment of parametric robustness conditions, namely, absence of positive feedback in the controller’s composition.
