Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Stable Lead Isotope Compositions in Coal, Coal Ash and Coal Fly Ash From Serbia

, 2022
The Republic of Serbia predominantly produces electricity in thermal power plants (TPP) Nikola Tesla (A i B), Kolubara and Kostolac. They are supplied from Kolubara basin mines (Nikola Tesla (A i B), Kolubara) which produces three quarters of Serbian lignite (about 70%), with the mean annual production about 30 million tons of coal and from Kostolac ...

COAL COMBUSTION ASH HAULBACK

Journal American Society of Mining and Reclamation, 1998
Coal mining disturbs large tracts of land which must be reclaimed. Unfortunately, iron sulfides which are common in most coals and the adjacent strata weather, forming acid mine drainage (AMD) which degrades surface and ground water. Burning of coal produces combustion by products, most of which are placed in ponds or landfills. Suitable disposal areas

Instantaneous Capture and Mineralization of Flue Gas Carbon Dioxide: Pilot Scale Study [PDF]

, 2010
Multiple CO2 capture and storage (CCS) processes are required to address anthropogenic CO2 problems. However, a method which can directly capture and mineralize CO2 at a point source, under actual field conditions, has advantages and could help offset ...

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...
