Sorbents with high efficiency for CO2 capture based on amines-supported carbon for biogas upgrading.
TL;DR: Sorbents for CO2 capture prepared by wet impregnation of a commercial active carbon with two CO2-philic compounds, polyethylenimine and tetraethylenepentamine, have revealed an appreciable CO2 separation selectivity.
Journal ArticleDOI
Biofiltration of methane and trace gases from landfills: A review
TL;DR: In this article, the main parameters affecting the biofiltration of methane are reviewed: temperature, moisture content, properties of the packing material, nutrient supply, oxygen requirements, formation of exopolysaccharides, and gas residence time.
Journal ArticleDOI
Techno-economic and environmental process evaluation of biogas upgrading via amine scrubbing
TL;DR: In this paper, the authors presented a techno-economic and environmental analysis of biogas upgrading processes, with the removal of acid gases (CO2, H2S) from the biomethane produced from municipal solid wastes.

Comparative transcriptome analysis of Gastrodia elata (Orchidaceae) in response to fungus symbiosis to identify gastrodin biosynthesis-related genes
Chi Chu Tsai,Keh Ming Wu,Tzen Yuh Chiang,Chun Yen Huang,Chang-Hung Chou,Shu Ju Li,Yu-Chung Chiang,Yu-Chung Chiang +7 more
TL;DR: The gene expression of the two unique unigenes encoding monooxygenase and glycosyltransferase significantly increases from vegetative propagation corms to tubers, and the molecular basis of gastrodin biosynthesis in the tubers of G. elata is proposed.

Trace organic compounds in landfill gas at seven U.K. waste disposal sites
TL;DR: The trace volatile organic compounds (VOCs) in landfill gas were examined at seven U.K. waste disposal facilities and over 140 compounds were identified, of which more than 90 were common to all seven sites.
Journal ArticleDOI
Determination of Siloxanes and VOC in Landfill Gas and Sewage Gas by Canister Sampling and GC-MS/AES Analysis
TL;DR: In this paper, a new technique for sampling, identification, and quantification of siloxanes and volatile organic carbon (VOC) in landfill gas and sewage gas is presented, after sample collection using evacuated stainless steel canisters biogas was analyzed by gas chromatography-mass spectrometry/atomic emission spectroscopy.
Journal ArticleDOI
Characterization of Landfill Gas Composition at the Fresh Kills Municipal Solid-Waste Landfill
TL;DR: In this article, the average total nonmethane organic compound (NMOC) value for the Fresh Kills landfill was 438 ppmv (as hexane) versus the regulatory default value of 4000 ppmv( as hexane). Over 70 individual volatile organic compounds (VOCs) were detected and quantified in the landfill gas samples.

Attenuation of methane and volatile organic compounds in landfill soil covers
TL;DR: Mass balance calculations using the maximal oxidation rates obtained demonstrated that landfill soil covers have a significant potential for not only methane oxidation but also cometabolic degradation of selected volatile organics, thereby reducing emissions to the atmosphere.
