Progress in oxygen carrier development of methane-based chemical-looping reforming: A review
TL;DR: In this paper, the authors comprehensively review the recent advances for chemical-looping reforming of CH4 (CLR) technology, which breaks down the traditional CH4 reforming process (including steam and dry reforming) into two separate half-steps, namely CH4 oxidation and replenishment of oxygen carrier (OC) with appropriate oxidizing agents.
Journal ArticleDOI
GC-MS and TG-FTIR Study of Petroleum Ether Extract and Residue from Low Temperature Coal Tar
Ming Sun,Xiaoxun Ma,Qiu-Xiang Yao,Rucheng Wang,Yan-Xing Ma,Feng Guang,Jian-Xuan Shang,Long Xu,Yan-hong Yang +8 more
TL;DR: In this article, heavy coal tar was extracted with petroleum ether (PE) under ultrasonic irradiation and separated into PE soluble and insoluble fractions, and the PE insoluble fraction was extracted in a Soxhlet extractor with PE and methanol (MeOH), respectively.
Journal ArticleDOI
Catalytic CH4 reforming with CO2 over activated carbon based catalysts
Long Xu,Long Xu,Yanan Liu,Yanjun Li,Zhu Lin,Xiaoxun Ma,Yulong Zhang,Morris D. Argyle,Morris D. Argyle,Maohong Fan +9 more
TL;DR: In this article, the authors compared the performance of several activated carbon (AC) based catalysts for CH 4 reforming with CO 2, including raw AC and AC modified with HNO 3 and NaNO 3, designated as AC-HNO3 and AC-NaNO 3, respectively.
Journal ArticleDOI
Pyrolysis characteristics and kinetics of residue from China Shenhua industrial direct coal liquefaction plant
Long Xu,Long Xu,Mingchen Tang,Lin’e Duan,Baolin Liu,Xiaoxun Ma,Yulong Zhang,Morris D. Argyle,Morris D. Argyle,Maohong Fan +9 more
TL;DR: In this paper, the authors comprehensively investigated the pyrolysis characteristics of the direct coal liquefaction residue (DCLR) from China Shenhua industrial direct coal liquidation plant, and the results showed that the interaction among the fractions is unfavorable for the evolution of volatile matter.
Journal ArticleDOI
Effect of Ce on 5 wt% Ni/ZSM-5 catalysts in the CO 2 reforming of CH 4 reaction
TL;DR: In this article, the promotional effect of Ce on Ni/ZSM-5 catalysts in the CO 2 reforming of CH 4 reaction was investigated in a fixed-bed reactor at atmospheric pressure.
