Abstract The process of CO 2 hydrogenation into methanol has recently attracted more attention for reducing , a main green-house gas in the atmosphere. In addition, can be used as fuel or basic chemical to satisfy growing demand energy world. this study, performance NaA membrane reactor on yield and selectivity obtained from was evaluated at different reaction conditions by varying temperature, pressure, hourly space velocity (GHSV) H /CO ratio. results show that yields selectivities (MR)...
The influences of La addition on the properties and performance xLa/ZSM-5 additives with various loading (x is molar ratio La/Al, x = 0.25-1) for vacuum gasoil (VGO) cracking reactions were studied. Samples deactivated via steaming treatment 100% steam, 20 hours, 816 °C. highest promoting effect was obtained 0.25La sample. higher loadings decrease enhancement La. XRD, BET NH3-TPD results demonstrated that use low La3+ concentration solution during step could lead to a better interaction...
The direct cracking of Bach Ho crude oil, having API gravity 41°, over equilibrium FCC catalyst (Ecat), modified (HT-FCC) and ZSM-5 additive were studied at 620–650 °C using short-contact-time micro activity testing unit. HT-FCC was prepared by the treatment Ecat with oxalic acid in reflux condition. This largely improves porosity while keeping particle size Ecat. Hence, it leads to an important enhancement catalytic activity. Due high catalyst, oil can be performed a low catalyst-to-oil...

<title>Abstract</title> In this work, hierarchical H-ZSM-5 catalysts (Si/Al molar ratio = 20, 30) with different levels of mesoporosity and acid strength were prepared via e-beam irradiation post-synthesis treatment tested as propylene-increasing FCC additives. It was found that higher specific surface areas highly accessible porous systems obtained among the irradiated samples.

Abstract Manganese dioxide, in particular α-MnO 2 , is one of the advanced inorganic nanomaterials having wide applications many areas. Hence, understanding crystallization pathways, morphologies, and formation mechanism defects its structure importance, not only for fundamental science but also practical applications. Herein, different physically chemically based methods, such as Neutron Diffraction (ND), XRD, SEM, TPR- H TGA-DSC, FT-IR, Positron Annihilation Lifetime (PAL), Doppler...
In Vietnam for recent years, a large amount of hazardous waste containing nickel (Ni) derived from discharged catalyst fertilizer plants has caused environmental problems in landfill overloading and the risk soil or surface water sources pollution. Taking advantage catalyst, recycling Ni components then synthesizing new catalysts apply mono-nitrogen oxides (NOx) treatments is an approach to bring about both economic benefits.
In this study, the influence of Mn content on NOx decomposition in presence oxygen over xMn/BaO/Al2O3 catalysts (x is molar ratio Mn/Ba) was investigated. Samples were characterized by N2 adsorption, XRD and SEM-EDX. The loading, dispersion Ba surface BET area are key factors affecting removal activity catalysts. maximum conversion obtained with 0.5 MnBa/Al sample. Lower higher loading resulted a significant loss overall efficiency conversion. lower at (x=0.1) demonstrated that oxide...
