The Characteristics of the After-Combustion in a Commercial CFBC Boiler Using the Solid Waste Fuel

open access: yesEnergies, 2022
A CFBC (Circulating Fluidized Bed Combustor) boiler for combusted SRF (Solid Refused Fuel) is designed for solid waste combustion and power generation. The boiler consumes about 200 tons/day of SRF and generates 60 ton/h of steam or 10 MWe in electricity.

Greenhouse gas mitigation in agriculture [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2007
Agricultural lands occupy 37% of the earth's land surface. Agriculture accounts for 52 and 84% of global anthropogenic methane and nitrous oxide emissions. Agricultural soils may also act as a sink or source for CO2, but the net flux is small. Many agricultural practices can potentially mitigate greenhouse gas (GHG) emissions, the most prominent of ...

Hydrogen and formate production and utilisation in the rumen and the human colon

open access: yesAnimal Microbiome, 2022
Molecular hydrogen (H2) and formate (HCOO−) are metabolic end products of many primary fermenters in the mammalian gut. Both play a vital role in fermentation where they are electron sinks for individual microbes in an anaerobic environment that lacks ...

Experimental Analysis of Reaction Heat of CO2 Absorption of Phase Change Absorber AEP-DPA at Low Partial Pressure

open access: yesEnergies, 2023
The reaction heat of CO2 absorption by organic amines is directly related to the regenerative heat consumption of absorbers. Therefore, it is necessary to study and determine the heat of absorption reaction and heat of regeneration reaction of CO2 ...

Changes in the deep subsurface microbial biosphere resulting from a field-scale CO2 geosequestration experiment

open access: yesFrontiers in Microbiology, 2014
Subsurface microorganisms may respond to increased CO2 levels in ways that significantly affect pore fluid chemistry. Changes in CO2 concentration or speciation may result from the injection of supercritical CO2 (scCO2) into deep aquifers.
