The product distribution of methanol to hydrocarbons conversion over SAPO-34 and ZSM-5 catalysts was studied using thermodynamic equilibrium and Anderson-Schulz-Flory (ASF) distributions. The equilibrium compositions were calculated using constrained Gibbs free energy minimization. The effect of catalyst type was considered by setting upper limits to product carbon number due to sh...

The Front Cover illustrates an artwork design for showcasing the developed bifunctional NiRe/SAPO-11 catalyst along with “KHON”, masked dance drama in Thailand. In their Research Article, A. Srifa and co-workers designed Re nanoparticles decorated on Ni/SAPO-11 economically combined process of direct triglycerides hydro-deoxygenation isomerization into low-cold flow diesel. diesel production co...

Expanding the range of supercapacitor operation to temperatures above 100 °C is important because this would enable capacitors to operate under the severe conditions required for next-generation energy storage devices. In this study, we address this challenge by the fabrication of a solid-state supercapacitor with a proton-conducting Sn(0.95)Al(0.05)H(0.05)P(2)O(7) (SAPO)-polytetrafluoroethylen...

an account is presented on investigation of the effects of synthesis parameters, i.e., reaction sources, silica to alumina ratio, acid molar ratio and crystallization conditions on the crystallinity, morphology and particle size of sapo-34. the synthesis conditions were designed to produce small particles with narrow size range. the prepared samples were characterized by xrd and sem techniques ...

Efficient and one-pot conversion of biomass-derived carbohydrate into highly value-added 5-hydroxymethylfurfural (HMF) is a crucial reaction step for the valorization biomass resources toward bio-based chemicals fuels. In this work, series Sn/SAPO-34 catalysts were prepared through impregnation evaluated in glucose to HMF. The physicochemical properties systematically characterized by SEM, XRD,...

Commercialized silicoaluminophosphate-34 (SAPO-34) zeolite was successfully blended in the polyethersulfone (PES) polymer to prepare mixed matrix membranes (MMMs). The CO2 permeability and CO2/CH4 ideal selectivity of 30 wt% SAPO-34/PES MMM at 0.1 MPa 35 °C were 15 barrer 51, respectively. In our previous paper, PES MMMs using laboratory-made SAPO-34 provided both higher than neat membrane. per...

Design/methodology/approach: We conducted a user study in which users evaluated the relevance of documents retrieved by 4 search engines in 2 different health information needs. Users could choose between generalist (Bing, Google, Sapo and Yahoo!) and health-specific search engines (MedlinePlus, SapoSaúde and WebMD). We then analyse the differences between search engines and groups of informati...

The ethanol dispersion method was employed to synthesize a series of MnOx/SAPO-34 catalysts using SAPO-34 with the hierarchical pore structure as zeolite carrier, which were prepared by facile acid treatment citric acid. Physicochemical properties characterized XRD, XPS, BET, TEM, NH3-TPD, SEM, FT-IR, Py-IR, H2-TRP and TG/DTG. NH3-SCR performances evaluated at low temperatures. Results show tha...
