Special Issue Information

Dear Colleagues,

The chemical-looping process provides a solution for clean and efficient conversion into value-added products, e.g., inherent CO2 capture, hydrogen, syngas, chemicals, etc. Derived from chemical-looping combustion, many applications on gas, liquid, and solid fuels were proposed and demonstrated, including reformation, partial oxidation, dehydrogenation, etc. The chemical-looping process allows to produce high-value products via inherent separation and flexible utilization of lattice oxygen.

In recent years, significant progress has been made on various chemical-looping technologies, from micro mechanism study to macro up-scaling demonstration. Currently, chemical looping represents one of the most attractive routes for fuel conversion. However, this research area is still far from being adequate, and the future focuses will be combined with various areas, such as heterogeneous catalysis, particle technology, material science, reactor design, system engineering, etc.

This Special Issue on “New Trends in Chemical Looping” seeks high-quality works covering the latest progress in low-carbon and clean production from the chemical-looping concept. Topics include but are not limited to:

  • Innovative oxygen-carrying or multifunctional materials;
  • Novel concept or application of the chemical-looping process;
  • New solutions to the issues on chemical looping, e.g., agglomeration, attrition, etc.;
  • New demonstration or reactor design of the chemical-looping process.

Abstract
Due to their low concentration and complex nature, the low-cost online and real-time monitoring of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) is a challenge.

Due to their low concentration and complex nature, the low-cost online and real-time monitoring of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) is a challenge. In this paper, based on a coupling adsorption model of activated carbon and the relationship of PCDD/Fs and flue gas, an online monitoring system with real-time control of final PCDD/F emissions was built for the tracing and control of PCDD/F emissions in municipal solid waste incinerators (MSWIs). According to the online monitoring system, the effects of activated carbon concentration, the specific surface area of activated carbon (AC), operating temperature, contact time, fly ash concentration, residence carbon concentration of fly ash, and the lime concentration of final PCDD/F emissions were discussed. These MSWI operating parameters for reaching standards of 0.1 ng international toxic equivalents (TEQ)/Nm3 and 0.05 ng TEQ/Nm3 were summarized by the predicting model based on several published models.

Drying has been widely studied as a necessary process in biomass utilization. The steam diffusion law plays an important role in drying kinetics. The drying kinetics of a single biomass particle using Fick’s second law of diffusion was studied in this paper. A parabolic relationship appeared between the critical moisture content and temperature. The critical moisture content decreased with the increase in drying temperature and the initial moisture content. The drying temperature had a significant effect on the effective diffusivity and coefficient of mass transfer during the dramatically falling period of the biomass drying process. However, it was affected by the effective diffusivity and coefficient of mass transfer during the slowly falling period. The initial moisture caused the opposite effect during the different periods. The normalized biomass moisture content generally increased with the increase in drying temperature, and decreased with the increase in initial moisture content. The initial moisture content had an effect on the normalized biomass moisture during the slowly rising period. Meanwhile, the drying temperature had an effect on the normalized biomass moisture during the whole period. The critical moisture content and the normalized biomass moisture content had negative relevant relationship. This study provides some valuable conclusions regarding the biomass drying process.
