Carbon-doped alumina (CDA) beads with different carbon contents were prepared by an ammonium alginate (ALG) assisted sol–gel method via changing the concentration of ALG in preparation process, which were used as the support of Pt–Sn–K catalysts. XRF, XRD, BET, TEM, EDS, NH 3 -TPD, TG and Raman techniques were employed to characterize the physical–chemical properties of CDA materials and Pt–Sn–K catalysts. Results showed that the as-prepared CDA materials all contained carbon and the carbon… 

MgF2-Modified Hydrotalcite-Derived Composites Supported Pt-In Catalysts for Isobutane Direct Dehydrogenation

Here, a simple method was developed to prepare an MgF2-modified hydrotalcite-derived composite, which was used as support for the Pt-In catalyst for isobutane direct dehydrogenation. The catalysts,

Recent progress in heterogeneous metal and metal oxide catalysts for direct dehydrogenation of ethane and propane.

For different classes of the most-promising catalysts in the selective dehydrogenation of ethane-to-ethylene and propane- to-propylene, their syntheses, structural information, catalytic properties and mechanisms are comparatively summarized.

Study of Gas Sensitivity of SnO2 ❬Nb❭ Film in Liquefied Petroleum Gas

Abstract A technology has been developed for obtaining a semiconductor solid solution SnO 2 + Nb 2 O 5 (80 : 20 wt %) and for manufacturing a thin-film nanoscale resistive sensor. The gas-sensitive

Crude oil exploration in Africa: socio-economic implications, environmental impacts, and mitigation strategies

This report highlights some recommendations that may ensure ethical and sustainable practices toward minimizing negative impacts and improving the quality of life in affected communities and provides insight into the environmental and socio-economic implications of crude oil exploration in Africa.

One-Step Fabrication of PtSn/γ-Al2O3 Catalysts with La Post-Modification for Propane Dehydrogenation

The catalytic dehydrogenation of propane to propene is an alternative technique to supplement the traditional steam cracking and catalytic cracking process for satisfying the continuously increasing



Carbon-covered Alumina: A Superior Support of Noble Metal-like Catalysts for Hydrazine Decomposition

Carbon-covered alumina (CCA) were synthesized from mesoporous alumina and a series of carbon sources (including sucrose, furfuryl alcohol, and benzene). They had structural properties of alumina and

The as-prepared CCA possessed the texture of alumina and the surface properties of carbon or both carbon and alumina depending on the carbon coverage and number of carbon layers in CCA.

Influence of support on the catalytic properties of Pt–Sn–K/θ-Al2O3 for propane dehydrogenation

A study on the performance of Pt(0.3 wt%) Sn(0.2 wt%) K(0.5 wt%) catalysts supported on four different theta-Al2O3 for propane dehydrogenation is reported in this study. The theta-Al2O3 used as
