Bioenergy recovery from landfill gas: A case study in China

Wei WANG, Yuxiang LUO, Zhou DENG

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 1,   Pages 20-31 doi: 10.1007/s11783-009-0012-9

Abstract: Landfill gas (LFG) utilization which means a synergy between environmental protection and bioenergy recovery was investigated in this study. Pressure swing adsorption technology was used in LFG purification, and laboratory experiment, pilot-scale test, and on-site demonstration were carried out in Shenzhen, China. In the laboratory experiment, A-type carbon molecular sieve was selected as the adsorbent by comparison of several other adsorbents. The optimal adsorption pressure and adsorption time were 0.25 MPa and 2 min, respectively, under which the product generation rate was 4.5 m /h and the methane concentration was above 90%. The process and optimization of the pilot-scale test were also reported in the paper. The product gas was of high quality compared with the National Standard of Compressed Natural Gas as Vehicle Fuel (GB18047-2000), when the air concentration in feed gas was under 10.96%. The demonstration project was composed of a collection system, production system, and utilization system. The drive performance, environmental protection performance, and economic feasibility of the product gas – as alternative fuel in passenger car, truck, and bulldozer – were tested, showing the feasibility technology for LFG utilization.

Lignin-based polymer with high phenolic hydroxyl group content prepared by the alkyl chain bridging method and applied as a dopant of PEDOT

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 8,   Pages 1075-1084 doi: 10.1007/s11705-022-2272-x

Abstract: Inspired by the importance of the phenolic group to the electron transporting property of hole transport materials, phenolic hydroxyl groups were introduced in lignosulfonate (LS) via the alkyl chain bridging method to prepare phenolated-lignosulfonate (PLS). The results showed that the phenolic group was boosted from 0.81 mmol∙g–1 of LS to 1.19 mmol∙g–1 of PLS. The electrochemical property results showed two oxidation peaks in the cyclic voltammogram (CV) curve of PLS, and the oxidation potential of the PLS-modified electrode decreased by 0.5 eV compared with that of LS. This result indicates that PLS is more easily oxidized than LS. Based on the excellent electron transporting property of PLS, PLS was applied as a dopant in poly(3,4-ethylenedioxythiophene) (PEDOT, called PEDOT:PLSs). PLS showed excellent dispersion properties for PEDOT. Moreover, the transmittance measurement results showed that the transmittance of PEDOT:PLSs exceeded 85% in the range of 300–800 nm. The CV results showed that the energy levels of PEDOT:PLSs could be flexibly adjusted by PLS amounts. The results indicate that the phenolic hydroxyl group of lignin can be easily boosted by the alkyl chain bridging method, and phenolated lignin-based polymers may have promising potential as dopants of PEDOT to produce hole transporting materials for different organic photovoltaic devices.

Progress in Studies on the Key Technology of Tritium Extract ionfrom Reactor Tritiated Heavy Water

Sun Ying,Wang Heyi,Sang Ge,Luo Yangming,Cao Wei,Liu Yunnu,Xiong Yifu

Strategic Study of CAE 2007, Volume 9, Issue 5,   Pages 1-6

Abstract:

Based on the CECE-GC experimental system,  with a disposal capability of 10 t/a of tritiated heavy water,   the demonstration experiment of recovering deuterium from light water containing deuterium and the simulation operation of recovering tritium from tritiated heavy water with tritiated light water are introduced.  The system has been operated for 240 h.  The total concentration factor of CECE is about 4,  and the separation factor of tritium is around 10.  The 8m3 /d GC system has recovered 90 % hydrogen from 10.5 m3 tritiated hydrogen in 23 h,   the tritium is depleted to more than 1 000 times.   This experimental system is an important basis for further engineering research.
