    Abstract
    Mn-based catalysts are often used for catalytic reduction of NO and catalytic degradation of chlorobenzene. In this work, the promotion mechanism of SnO2 modification was investigated. The activities of Sn–Mn–Ce–Co–Ox catalyst were the best when the SnO2 content was 8%. In the temperature range from 120 to 330 ℃, the NO conversion was above 90%, and the T50 and T90 of CB decreased to 127 ℃ and 183 ℃. The structure of the catalyst was characterized, and it was found that the catalytic effects of SnO2 on pollutant degradation performance of Sn–Mn–Ce–Co–Ox catalyst were mainly as follows: (1) leading to the formation of a large number of Mn4+; (2) increasing the amount of chemisorbed oxygen on the catalyst surface; and (3) improving the redox performance of the catalyst. CHCl3, CCl4, C2HCl3, and C2Cl4 intermediate products were generated in the catalytic reaction, covering the catalytic site. Graphical abstract: [Figure not available: see fulltext.]

      Kinetic and catalytic performance of a BI-porous composite material in catalytic cracking and isomerisation reactions

      Al-Khattaf, S.; Odedairo, T.; Balasamy, R. J. (The Canadian Journal of Chemical Engineering, Wiley, 2012-01-10) [Article]
      Catalytic behaviour of pure zeolite ZSM-5 and a bi-porous composite material (BCM) were investigated in transformation of m-xylene, while zeolite HY and the bi-porous composite were used in the cracking of 1,3,5-triisopropylbenzene (TIPB). The micro/mesoporous material was used to understand the effect of the presence of mesopores on these reactions. Various characterisation techniques, that is, XRD, SEM, TGA, FT-IR and nitrogen sorption measurements were applied for complete characterisation of the catalysts. Catalytic tests using CREC riser simulator showed that the micro/mesoporous composite catalyst exhibited higher catalytic activity as compared with the conventional microporous ZSM-5 and HY zeolite for transformation of m-xylene and for the catalytic cracking of TIPB, respectively. The outstanding catalytic reactivity of m-xylene and TIPB molecules were mainly attributed to the easier access of active sites provided by the mesopores. Apparent activation energies for the disappearance of m-xylene and TIPB over all catalysts were found to decrease in the order: EBCM>EZSM-5 and EBCM>EHY, respectively. © 2012 Canadian Society for Chemical Engineering.

      Evolved Gas Analysis and Kinetics of Catalytic and Non-Catalytic Pyrolysis of Microalgae Chlorella sp. Biomass With Ni/θ-Al2O3 Catalyst via Thermogravimetric Analysis

      Farooq, Wasif; Ali, Imtiaz; Raza Naqvi, Salman; Sajid, Mohd; Abbas Khan, Hassnain; Adamu, Sagir (Frontiers in Energy Research, Frontiers Media SA, 2021-11-25) [Article]
      This study investigates the efficacy of a prepared Ni/θ-Al2O3 catalyst during the pyrolytic conversion of Parachlorella kessleri HY-6 and compares the results with non-catalytic conversion. The catalyst was characterized by techniques such as Brunauer–Emmett–Teller (BET) for surface area, acidity, and X-ray powder diffraction (XRD). Isoconversional and combined kinetic methods were used to study the pyrolytic kinetics of the process. Ni/θ-Al2O3 was used at 10, 20, and 30% of the algal biomass. The addition of Ni/θ-Al2O3 facilitated the conversion by lowering the mean activation energy during pyrolysis. The catalytic effect was more pronounced at lower and higher conversions. The presence of the catalyst facilitated the pyrolysis as indicated by the lower value of activation energy and ∆H, and ∆G. Gases evolved during pyrolysis were qualitatively analyzed by FTIR to see the effect of catalyst on evolved gas composition during the pyrolysis process.
