Different mixing modes for biogas plants using energy crops
TLDR
In this paper, different mixing modes were investigated in three equal laboratory scale digesters with a liquid volume of 22 l. During the experiments the gas volume flow was measured continuously, the gas quality once a day and the dry matter and volatile solids once a week.About:

A review on solid adsorbents for carbon dioxide capture
Seul-Yi Lee,Soo-Jin Park +1 more
TL;DR: In this paper, dry solid adsorbents are classified into non-carbonaceous (e.g., zeolites, silica, metal-organic frameworks and porous polymers, alkali metal, and metal oxide carbonates) and carbonaceous materials with a focus on recent research.

Effects of mixing on the result of anaerobic digestion: Review
TL;DR: In this article, an anaerobic digester is used to keep the solids in suspension and homogenize the incoming feed with the active microbial community of the digester content.
Journal ArticleDOI
Influence of mixing on anaerobic digestion efficiency in stirred tank digesters: A review.
TL;DR: There is no motivation to continue to operate stirred tank anaerobic digesters as CSTRs if AD energy efficiency is to be improved, and AD energy production efficiency can be achieved with optimized intermittent mixing.

A Review of the Role of Critical Parameters in the Design and Operation of Biogas Production Plants
TL;DR: In this paper, the importance of the selection of operational parameters in existing technologies and their impact on biogas yield is discussed, including feedstock utilization (substrate, inoculum, codigestion and pretreatment), process condition (pH, temperature, pressure, and reactor design), reactor control (HRT and OLR), and inhibition (Ammonia and VFAs).
Journal ArticleDOI
The effects of different mixing intensities during anaerobic digestion of the organic fraction of municipal solid waste.
TL;DR: The results show that a lower mixing intensity leads to a higher biogas production rate and higher total biogAS production in both cases and optimal mixing can improve the energy efficiency of the anaerobic digestion process.
