Alkaline modification of ZSM-5 catalysts for methanol aromatization: The effect of the alkaline concentration

Zhenhao Wei,Tengfei Xia,Minghui Liu,Qingsheng Cao,Yarong Xu,Kake Zhu,Xuedong Zhu

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 4,   Pages 450-460 doi: 10.1007/s11705-015-1542-2

Abstract: The effects of alkaline treatment on the physical properties of ZSM-5 catalysts and on their activitiesA mild alkaline treatment (0.2 and 0.3 mol/L NaOH) created mesopores in the parent zeolite with no obviousIn addition, more mesopores were produced than with the mild alkaline treatment.Treatment with a higher alkaline concentration (0.5 mol/L) greatly reduced the number of Brønsted acidWhen the alkaline-treated catalysts were washed with acid, some of the porosity was restored and a slight

A “Seawater-in-Sludge” approach for capacitive biochar production via the alkaline and alkaline earth

Xiling Li, Tianwei Hao, Yuxin Tang, Guanghao Chen

Frontiers of Environmental Science & Engineering 2021, Volume 15, Issue 1, doi: 10.1007/s11783-020-1295-0

Abstract: Abstract • Capacitive biochar was produced from sewage sludge. • Seawater was proved to be an alternative activation agent. • Minerals vaporization increased the surface area of biochar. • Molten salts acted as natural templates for the development of porous structure. Sewage sludge is a potential precursor for biochar production, but its effective utilization involves costly activation steps. To modify biochar properties while ensuring cost-effectiveness, we examined the feasibility of using seawater as an agent to activate biochar produced from sewage sludge. In our proof-of-concept study, seawater was proven to be an effective activation agent for biochar production, achieving a surface area of 480.3 m2/g with hierarchical porosity distribution. Benefited from our design, the catalytic effect of seawater increased not only the surface area but also the graphitization degree of biochar when comparing the pyrolysis of sewage sludge without seawater. This leads to seawater activated biochar electrodes with lower resistance, higher capacitance of 113.9 F/g comparing with control groups without seawater. Leveraging the global increase in the salinity of groundwater, especially in coastal areas, these findings provide an opportunity for recovering a valuable carbon resource from sludge.

Polysulfone and zirconia composite separators for alkaline water electrolysis

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 2,   Pages 154-161 doi: 10.1007/s11705-013-1331-8

Abstract: The novel composite separators composed of polysulfone and zirconia were prepared by phase inversion precipitation technique. This technique allows pre-evaporation time and extraction temperature to be varied in order to obtain optimal performances of the separators. In order to evaluate practical applicability of those composite separators, a small-scale electrolysis experimental apparatus was used to investigate the changes of cell voltage, gas purity and separator stability. The results revealed a decreased cell voltage compared to the conventional asbestos separators, and the gas purity and separator stability met the requirements for industrial use.
