Revolutionary shale gas production has resulted in increasing interest the use of methane for producing various types high-value chemicals and among them is aromatics via dehydroaromatization (MDA). Progresses achieved area MDA during last 6 years are significant. However, a review this lacking. This designed to fill gap. The not only discusses he development catalysts, including conventional molybdenum (Mo)-based catalyst non-Mo-based catalysts novel catalysts. Also, insights associated...
Abstract Rare-earth element (REE) demand is expected to increase by a factor of up 7 2040. Recycling avoids the significant hurdles associated with opening new mines, but collection and disassembly REE-containing devices are barriers. Absolute relative abundances REEs co-occurring constituents differ significantly in secondary compared primary sources, presenting challenges opportunities. REE concentrations typically low, manufactured include only desired REE, avoiding “REE balance problem”...
This work reports a dimethyl ether-driven fractional crystallization process for separating rare earth elements and transition metals. The has been successfully applied in the treatment of element-bearing permanent magnet leachates as an atom-efficient, reagent-free separation method. Using ~5 bar pressure, solvent was dissolved into aqueous system to displace contained metal salts solid precipitates. Treatments at distinct temperatures ranging from 20-31 °C enable either lanthanide-rich or...
Supercritical isobutane regeneration of an ultrastable Y-zeolite (USY) alkylation catalyst was examined in a continuous, automated reaction/regeneration system. Two feeds were studied: synthetic isobutane/2-butene blend and commercial refinery isoparaffin/olefin blend. Synthetic feed experiments showed that high levels butene conversion maintained for time on stream more than 200 h, product quality maintenance relatively stable over the course experiment, using 3 h reaction/3 cycle. Thirty...
Catalytic performance of Mo/HZSM5 and Ru-Mo/HZSM5 catalysts prepared by vaporization-deposition molybdenum trioxide impregnation with ammonium heptamolybdate was analyzed in terms catalyst activity selectivity, nitrogen physisorption analyses, temperature-programmed oxidation carbonaceous residues, reduction. Vaporization-deposition rendered the more selective to ethylene coke than impregnation. This result assigned lower interaction carbide zeolite acidic sites.
