Hydrogenation of methyl methacrylate under mild conditions using biosynthesis Ru catalyst
Hongling Zhou,Yangqiang Huang,Youwei Cheng,Lijun Wang,Xi Li 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.47 No.-
Hydrogenation of methyl methacrylate (MMA) was investigated over Ru-based catalyst supported onactive carbons (AC), which was prepared by bio-reduction method, using C. Platycladi (CP) leaf extract asreductant. By varying reaction temperature, hydrogen pressure and reaction time, hydrogenation ofMMA over the biosynthesis Ru-based catalyst was carried out, and resulted the optimum conditions,30 C (room temperature), 2.0 MPa, and 50 min. The as-prepared Ru/AC catalyst showed high catalyticactivity towards the hydrogenation of MMA, affording 100% of MMA conversion even under mildconditions without solvent and methyl isobutyrate was the only product.
Kinetic modeling of C2–C7 olefins interconversion over ZSM-5 catalyst
Lei Ying,Jiajia Zhu,Youwei Cheng,Lijun Wang,Xi Li 한국공업화학회 2016 Journal of Industrial and Engineering Chemistry Vol.33 No.-
The kinetics of C2–C7 olefins interconversion were studied by feeding individual olefin into industrialZSM-5 catalyst at temperatures of 400–490 8C, space time of 0.0046–0.34 h and partial pressure of13.1 kPa. A kinetic model involving oligomerization, cracking and aromatization of olefins wasestablished. The results showed that the calculated apparent activation energy was negative foroligomerization reactions and positive for cracking reactions. The proposed kinetic model was able topredict the product concentrations in the C2–C7 olefins interconversion over ZSM-5 catalyst, with R2values ranged from 0.969 to 0.996 for the major species.
