“…Post-treatment with chemicals is considered a simple and practical strategy to adjust the composition of the zeolite framework. As shown in Table 1, the Si/Al ratio of commercial H-MOR increased after the treatment with citric acid and phosphoric acid, which was consistent with other published works [21,22]. Furthermore, when a higher concentration of citric acid solution was used, a more severe dealumination was observed.…”

“…Both the total pore volume and mesopore volume increased after dealumination treatment, indicating that mesoporosity increased after treatment with steaming or acid leaching. The BET surface areas and pore volumes of the acid treated zeolites (HClZ8 and CAZ8) increased remarkably as compared with the parent HMCM-68, which can be ascribed to dealumination during the modification process [29,30].…”

“…Citric acid loading on Hβ was prepared on the basis of the reported literature ( 17 , 23 , 27 ). Briefly, a 20 g sample of Hβ was added to 200 ml of critic acid aqueous solution, and the resulting suspension was stirred at room temperature for 16 h. And then washed, dried and calcined.…”

In the present work, effects of reaction temperature, reactant concentration, catalyst loading, and rotation speed on the kinetics of sesamin conversion in a sesame oil system were studied by using citric acid loading on Hβ zeolite (CA/Hβ) as a catalyst. A kinetic model was built for sesamin conversion. The kinetic model fits correctly the experimental concentration of sesamin and asarinin (RS⁢e⁢s⁢a⁢m⁢i⁢n2 = 0.93 and RA⁢s⁢a⁢r⁢i⁢n⁢i⁢n2 = 0.97). The sesamin conversion is an endothermic reaction (△HrIso = 3 4.578kJ/mol). The CA/Hβ catalyst could be easily regenerated by calcination, and there was no obvious loss of catalytic activity when reused. Knowledge of the sesamin conversion is of great significance for guiding production and improving the value and nutrition of sesame oil. In a word, this study lays the foundation for the scale-up of the production of asarinin from sesame oil using CA/Hβ as the catalyst.
