Summary: The study investigates the performance of SMBR in reversible reactions and finds that both kinetics and adsorptive separation are important factors. Non-isothermal operation can significantly improve unit throughput under certain conditions, while feed concentration and reaction enthalpy have minor effects on the optimal solutions. Decision variables based on flow rate ratios and internal concentration profiles can explain the trends of Pareto optimal solution.

Summary: An elastic foam-bed reactor based on open-cell polymer foams was designed to enhance gas-liquid mass transfer of CO2 through compression/decompression cycles. The cycles, ensured by a crankshaft, require low additional electric power (<50 Watts) but significantly improve the mass transfer by one order of magnitude compared to fixed foam-bed reactor. Carbonic anhydrase-supported foam, using a supramolecular hydrogel for continuous applications, improves CO2 capture.

Summary: A pyrrhotite and sulfur-circulating packed bed reactor (PS-CPBR) was used to study the removal process and mechanism of NO3--N and PO43--P with different electron donors. The results showed that the removal performance of mixed electron donors (pyrrhotite and sulfur) was better than that of single electron donor (pyrrhotite). The optimum conditions for NO3--N and PO43--P removal in the PS-CPBR were HRT of 12 h and C/N of 0, with average removal efficiencies of 100% and 86.39% respectively. Sulfur in mixed electron donors promoted the dissolution of pyrrhotite and formation of polysulfide, enhancing the effectiveness of electron donors for NO3--N removal, while PO43--P was removed through FePO4 precipitation. Microbial and functional gene analyses indicated that different electron donors influenced microbial community abundance and denitrification functional genes. Mixed electron donors also increased protein content and reduced electron transfer resistance in biofilms.

Summary: In this study, a NiO modified CaSO4 oxygen carrier with a desired core-shell structure was successfully prepared, enhancing its reactivity. Experimental evidence confirmed that the modified gypsum ore activated the reduced nickel in the residual char and oxidized it back to active NiO, while fixing the released sulfur gas from side reactions. The prepared NiO modified CaSO4 oxygen carrier showed promising resistance to sintering and good regeneration for potential application in real chemical looping combustion systems.
