A study on naphtha catalytic reforming reactor simulation and analysis [PDF]

Journal of Zhejiang University-SCIENCE B, 2005
A naphtha catalytic reforming unit with four reactors in series is analyzed. A physical model is proposed to describe the catalytic reforming radial flow reactor. Kinetics and thermodynamics equations are selected to describe the naphtha catalytic reforming reactions characteristics based on idealizing the complex naphtha mixture by representing the ...

Two-Stage Catalytic Conversion of Carbon Dioxide Into Aromatics Via Methane. [PDF]

Angew Chem Int Ed Engl
The development of a two‐stage process for converting CO2 via CH4 to C6H6 using a Ni/TiO2 catalyst in stage 1 and a Mo/ZSM‐5 catalyst stage 2. Thermodynamic calculations as well as experimentally varying parameters, aided in finding the optimal reaction conditions and reducing the coke deposition in stage 2.

Recent Advances in Catalytic Conversion of Bioethanol to 1,3-Butadiene: Reaction Mechanism, Catalyst Design, and Process Scalability. [PDF]

ChemSusChem
Catalytic conversion of ethanol to 1,3‐butadiene (BD) can proceed via one‐step and two‐step routes. In the one‐step process, pure and metal‐modified MgO–SiO2 catalysts enable direct ethanol transformation to BD, while ZrO2‐based catalysts drive the two‐step pathway.
