Hydrogen production from steam reforming of simulated bio-oil over Ce–Ni/Co catalyst with in continuous CO2 capture
TL;DR: In this article, a steam reforming of the simulated bio-oil over the CeNi/Co catalyst supported on Al 2 O 3 balls was performed, and the optimal results for hydrogen production were obtained at 700°C, the S/C ratio of 9 and the L s HSV of 0.23h −1, with the actual hydrogen yield of 83.8% and the H 2 (+CO+CH 4 ) yield of 94.1%.

Progress in low temperature hydrogen production with simultaneous CO2 abatement
Haisheng Chen,Haisheng Chen,Yulong Ding,Ngoc T. Cong,Binlin Dou,Binlin Dou,Valerie Dupont,Mojtaba Ghadiri,Paul T. Williams +8 more
TL;DR: In this article, a new process has been proposed and investigated for low temperature hydrogen production from hydrocarbons with simultaneous CO2 abatement, based on a concept involving simultaneous hydrogen production and CO2 removal, which uses a stationary catalyst phase and a continuously moving adsorbent phase for in situ removal of CO2 and ex situ regeneration of adsorbents.

Heat transfer of gas flow through a packed bed
Dongsheng Wen,Yulong Ding +1 more
TL;DR: In this paper, an experimental study of both the transient and steady-state heat transfer behavior of a gas flowing through a packed bed under the constant wall temperature conditions is presented. But the results reveal a large temperature drop at the wall region and the temperature drop depends on the axial distance from the inlet, whereas the wall-fluid heat transfer coefficient is better represented by the Li-Finlayson correlation.
