Co-inhibition of methanogens for methane mitigation in biodegradable wastes

Journal of Environmental Sciences, 2009
The inhibition effects and mechanisms of chlorinated methane and acetylene on methanogenesis in the anaerobic digestion process of the biodegradable wastes were investigated. It was found that both chloroform and acetylene could effectively inhibit methanogens while the biodegradability of the wastes was not affected.

Consequences of Surface Oxophilicity of Ni, Ni-Co, and Co Clusters on Methane Activation

Journal of the American Chemical Society, 2017
This study describes a new C-H bond activation pathway during CH4-CO2 reactions on oxophilic Ni-Co and Co clusters, unlike those established previously on Ni clusters. The initial C-H bond activation remains as the sole kinetically relevant step on Ni-Co, Ni, and Co clusters, but their specific reaction paths vary.

Methane from CO₂: Influence of different CO₂ concentrations in the flush gas on the methane production in BMP tests.

Waste management (New York, N.Y.), 2017
The influence of carbon dioxide (CO2) in the headspace gas on the specific methane (CH4) production of blank samples with just inoculum during Biochemical Methane Potential (BMP) tests was studied. The headspace of the bottles had been flushed with 15 different ratios of CO2 and N2 prior to incubation, while they were treated otherwise identically. The

Using Biochemical Methane Potential Assays to Aid in Co-substrate Selection for Co-digestion

Applied Engineering in Agriculture, 2011
There has been an increasing interest in manure anaerobic digestion ; however, economic constraints are still one of the limits to widespread use of the technology in the United States. Co-digestion of manure with other feedstocks has been noted as a way to increase the economic feasibility of animal feeding operation anaerobic digesters via increased ...

Methane homologation on Co supported catalysts

1997
The effect of adding K or Cu to Co catalysts has been examined for the two-stage CH 4 homologation reaction. C 2 + selectivity was more than doubled upon addition of K to Co/SiO 2 , whereas, addition of Cu to the same catalyst decreased C 2 + selectivity. These results are discussed in terms of the Co dispersion, support and dopant effects and the

Co₂-Enhanced Methane Production by Integration of Bamboo Biochar During Anaerobic Co-Digestion

Journal of Environmental Management
This study investigates the enhancement of methane production in anaerobic co-digestion (AcoD) through the introduction of exogenous CO₂ and the application of bamboo biochar. Exogenous CO₂ boosts biogas yield by providing an additional carbon source, which requires optimized solubility and pH buffering to ensure effective methanation.
