Near-infrared (NIR) spectroscopy has been successfully utilized for the rapid identification of six typical petroleum products such as light straight-run (LSR), naphtha, kerosine, light gas oil (LGO), gasoline, and diesel. The spectral features of each product were reasonably differentiated in the NIR region, and the spectral differences provided enough qualitative spectral information for disc...

10-membered ring IM-5 zeolite has shown excellent performance in many catalytic reactions. The efficient preparation of high silica by situ synthesis remains huge challenge. Here, with SiO2/Al2O3 ratio (SAR) 49–116 was acquired HNO3 treatment. An interesting stepwise dealumination behavior discovered during the whole acid-treatment process (based on XRF characterization). Extra-framework Si (EF...

Direct industrial application of x-ray absorption spectroscopy is demonstrated by research in catalysis (CO/H2 and naphtha reforming) and corrosion protection.

This paper described the discovering process of some shortcomings of the conventional fluid catalytic cracking (FCC) process and the proposed two-stage riser (TSR) FCC process for decreasing dry gas and coke yields and increasing light oil yield, which has been successfully applied in 12 industrial units. Furthermore, the multifunctional two-stage riser (MFT) FCC process proposed on the basis o...

The kinetic modeling of the hydrocracking a mixture polystyrene (PS) and vacuum gasoil (VGO) over PtPd/HY catalyst has been carried out. reactions have performed in batch reactor under following conditions: 380–420 °C; 80 bar; content PS feed, 10 wt%; catalyst/feed ratio, 0.1 mass; time, 30–300 min. Different reaction networks models studied, which evolution product distribution (unconverted PS...
