“…Figure 2B,C shows the variation in the gaseous product yield and P/E ratio with reaction temperature. Catalytic pyrolysis is an exothermic reaction, which meant that increasing the temperature increases the 1-pentene conversion, and thus increases the gaseous product yield for the catalysts prepared with different SLs, which is similar to the results previously reported by Hou et al 38 The catalytic pyrolysis of 1-pentene involves two cracking pathways: Monomolecular and bimolecular reaction pathways, which are summarized in Scheme 1. The proportion of the monomolecular and bimolecular reaction pathways reflects the changes in the P/E and P/B.…”

The acid property of the catalyst is usually one of the most important parameters for the selection and design of catalysts for catalytic pyrolysis of 1‐pentene. Here, seven catalysts with similar pore properties and different acid properties were evaluated and characterized in terms of three key properties: Total acid amount (TA), Brønsted to Lewis acid ratio (B/L), and strong to weak acid ratio (S/W). A database of the stoichiometric coefficients of 26 pyrolysis products was constructed. Then, a novel catalyst acid property‐included global reaction modeling method was developed, which was used to predict the yields of the 26 pyrolysis products. Besides, a suitable range of TA, B/L, and S/W was obtained for enhancing ethylene and propylene. The model thus can predict the product composition, and be used for the design and selection of the acid properties of catalysts. This simulation method can also be extended to other hydrocarbon systems.
