Comparative study of low temperature denitration performance of Mn-Ce/ACFA-TiO2 catalysts under oxy-fuel and air-fuel combustion flue gases

Gou, Xiang; Zhang, Ruiping; Xu, Guoyou; Zhao, Dong - In: Energy Reports 6 (2020), pp. 1545-1552

Low temperature selective catalytic reduction (SCR) catalysts were prepared by using acetic acid modified fly ash (ACFA) and TiO2 with the loading of Mn-Ce. The powder catalysts were characterized by BET, XRD and SEM. The effects of Mn-Ce molar ratio on the NO conversion of SCR catalyst were...

Can hydrogen and Carbon Capture and Storage (CCS) help decarbonize the coal power plants in Asia?

Habib, Ali - 2024

As the power sector is the largest GHG emitter, it is important to investigate the fuels used in this sector. In 2023, coal was the primary source of electricity supply, accounting for 35.9%. Natural gas came in second, representing 23%. Asia has the largest number of coal plants in operation,...

Pre-processing of coal combustion fly ash by classification for enrichment of rare earth elements

Lanzerstorfer, Christof - In: Energy Reports 4 (2018), pp. 660-663

Fly ash from the combustion of coal shows potential as a source of valuable metals like the rare earth elements (REEs). These are present in the fly ash at low concentrations. Thus, simple dry pre-processing methods that can produce REE-enriched fractions from the fly ash could improve the...

Refunding Emission Payments: Output-Based versus Expenditure-Based Refunding

Hagem, Cathrine; Hoel, Michael Olaf; Sterner, Thomas - 2020

We analyse two mechanism designs for refunding emission payments to polluting firms: output-based refunding (OBR) and expenditure-based refunding (EBR). In both instruments, emission fees are returned to the polluting industry, typically making the policy more politically acceptable than a...

Removal of high concentrations of NOx and SO2 from diesel off-gases using a hybrid electron beam technology

Zwolińska, Ewa; Sun, Yongxia; Chmielewski, Andrzej G.; … - In: Energy Reports 6 (2020), pp. 952-964

The removal of high inlet concentrations of NOx (>1000 ppm) and SO2 ( >500 ppm) from diesel engine off-gases was ….9 kGy irradiation dose for inlet concentrations of SO2 varying between 501 ppm and 723 ppm. The NOx removal efficiency … increased with increasing the absorbed dose and decreased with increasing the gas flow rate. NOx removal efficiency also …
