Direct Operation of Solid Oxide Fuel Cells on Low-Concentration Oxygen-Bearing Coal-Bed Methane with High Stability

19-Jan-2018 | Yong Jiao; Liyang Wang; Liqin Zhang; Wenting An; Wei Wang; Wei Zhou; Moses O. Tadé; Zongping Shao; Jianping Bai; Si- ..., Energy & Fuels, 2018

This paper studies the electrochemical feasibility of the direct conversion of low-concentration, oxygen-bearing coal-bed methane (CBM, 30 vol % CH4) to electricity via solid oxide fuel cells (SOFCs). A fuel cell with the LiLaNi–Al2O3/Cu catalyst layer was developed, and a maximum power output of ...

Estimation of Static Dissipater Additives in Aviation Turbine Fuels Using ASTM D7524 and ASTM D2624: Observation, Precautions, and Suggestions Thereof

19-Jan-2018 | Anil Yadav; Maya Chakradhar; Anju Chopra; J. Christopher; G. S. Kapur, Energy & Fuels, 2018

Static dissipater additives (SDAs) are conductivity improver additives that are added to aviation turbine fuels (ATFs) to avoid sudden increase in conductivity that may occur during transfer/pumping of ATF. STADIS 450 has been used globally as the SDA in aviation jet A1. The dosage of SDA into ...

Morphological Evolution of a Single Char Particle with a Low Ash Fusion Temperature during the Whole Gasification Process

19-Jan-2018 | Ming Liu; Zhongjie Shen; Qinfeng Liang; Jianliang Xu; Haifeng Liu, Energy & Fuels, 2018

The morphological evolution of a single char particle with a low ash fusion temperature (Tf) was investigated during the whole gasification process using a high-temperature stage microscope. The experimental results showed that the final shrinkage ratio of char particles at the temperature above ...

Chlorine-Induced High-Temperature Corrosion of Boiler Steels Combusting Sha Erhu Coal Compared to Biomass

19-Jan-2018 | Yacheng Liu; Weidong Fan; Xiaofeng Wu; Xiang Zhang, Energy & Fuels, 2018

Chlorine, as the harmful element with high volatility and reactivity existing in certain coal and biofuels, mainly contributes to severe deposit formation and high-temperature corrosion. Sha Erhu (SEH) coal is characterized with high amounts of alkali metal (mainly sodium, Na) and chlorine (Cl) ...

An Experimental Investigation of the Catalytic Activity of Natural Calcium-Rich Minerals and a Novel Dual-Supported CaO–Ca12Al14O33/Al2O3 Catalyst for Biotar Steam Reforming

19-Jan-2018 | Fengkui Yin; Priscilla Tremain; Jianglong Yu; Elham Doroodchi; Behdad Moghtaderi, Energy & Fuels, 2018

Tar removal plays a key role in the process efficiency and viability of biomass gasification for syngas production applications. Among currently available tar treatment technologies, catalytic cracking was found to be the most attractive due to minimal energy losses by avoiding cooling of the raw ...

Laboratory Study of CO2 Foam Flooding in High Temperature, High Salinity Carbonate Reservoirs Using Co-injection Technique

18-Jan-2018 | Ali M. AlSumaiti; Muhammad R. Hashmet; Waleed S. AlAmeri; Evans Anto-Darkwah, Energy & Fuels, 2018

In this research, an ethoxylated amine surfactant is co-injected with CO2 in a series of coreflooding experiments at typical Middle Eastern reservoir conditions of high temperature, high salinity, and in situ foam is generated to reduce gas mobility in the absence of oil. The effects of reservoir ...
