Summary: This study investigated the chemical looping gasification (CLG) of bituminite using NiFe2O4 oxygen carrier. The changes in the phase of the oxygen carrier during the reaction and the reaction mechanism were explored. The results showed that elevated temperature and adding steam facilitated the gasification reaction, and adding ZrO2 and alkali metal enhanced the performance of the oxygen carrier. The optimized reaction conditions yielded a carbon conversion rate of 95% and a syngas selectivity of 86%. After 20 redox cycles, the carbon conversion rate remained at around 90% and the syngas selectivity was stably maintained above 80%.

Summary: This study investigates the reformation of MSW pyrolysis volatiles using IFA, and the migration characteristics of HMs and Cl. Results show that the reformed pyrolysis oil has decreased O -and Cl-containing compounds, increased light hydrocarbons and calorific value, and produced more CH4 and H2 gases. The IFA absorbs Cl from volatiles during reforming, reducing HCl in the gas product. The toxicity of PCDD/Fs in IFA dramatically decreases with increasing reforming temperature. The used IFA at 800 degrees C has the lowest HMs leaching concentrations, meeting landfill requirements, while the used IFA at 500 degrees C has the maximum carbon deposition, providing an energy source for melting. This study demonstrates the potential for simultaneous disposal of IFA and recovery of high-quality MSW pyrolysis products, reducing the hazardous properties of IFA.

Summary: The study shows that municipal solid waste-derived biochar can serve as a catalyst support for low-cost syngas methanation. The impact of inorganics in different waste-derived chars on the methanation reaction was investigated. Acid-soluble inorganics significantly improved methanation activity, while water-soluble alkali metal salts were detrimental to the methanation activity of biochar-supported Ni catalysts. A new alkali-carbon index was created to evaluate the effect of inorganics on the methanation activity of char-supported catalysts.

Summary: The nature and role of Zn species in Zn-promoted HZSM-5 catalyst for catalytic cracking of HDPE thermal decomposing vapor were studied. Hydrogen reduction of Zn/Z5 significantly enhanced the aromatic yield. [ZnOH]+ and bridged Zn2+ species were identified as crucial species promoting BTX formation, with the former showing higher activity. Additionally, the synergy between Zn species and Brunsted acid sites on HZSM-5 increased the aromatic yield. Incorporation of Zn also promoted long-chain scission. Among the Zn/Z5 catalysts, hydrogen reduced 2 wt% Zn/Z5 (SAR=25) exhibited the highest BTX yield (48%) and selectivity (93%), while hydrogen reduced 2 wt% Zn/Z5 (SAR=50) achieved the highest yield of total aromatics (53%).

Summary: This paper proposes a grey box model for fuel consumption prediction of wing-diesel hybrid vessels based on feature construction. By using both parallel and series grey box modeling methods and six machine learning algorithms, twelve combinations of prediction models are established. A feature construction method based on the aerodynamic performance of the wing and the energy relationship of the hybrid system is introduced. The best combination is obtained by considering the root mean square error, and it shows improved accuracy compared to the white box model. The proposed grey box model can accurately predict the daily fuel consumption of wing-diesel hybrid vessels, contributing to operational optimization and the greenization and decarbonization of the shipping industry.
