Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 3,   Pages 289-296 doi: 10.1007/s11705-013-1345-2

Abstract: In order to find suitable catalysts that prevent the carbon deposition, NiO-MgO/Ce Zr O (CZO) supportedThe amount of Ni loading was fixed at 15 wt-% whereas the amount of MgO loading was varied from 5 toThe results revealed that the addition of MgO shifted the light-off temperatures to higher temperaturesThis is because the Ni surface was partially covered with MgO, and the strong interaction between NiOand NiMgO over CZO support led to the difficulty in reducing NiO to active Ni and thus less catalytic

Emergy evaluation of polygeneration systems

WANG Lingmei, LI Zheng, NI Weidou

Frontiers in Energy 2007, Volume 1, Issue 2,   Pages 223-227 doi: 10.1007/s00000-007-0030-x

Abstract: To expand the application range of the emergy evaluation method, an emergy evaluation index, which can reflect the particular feature of polygeneration systems, has been elaborated on the basis of energy and emergy conservation, guided by the fundamental principle of emergy analysis. With this index, the cost structure, emission effect and energy saved were all considered on the same level of importance. To exemplify, some power polygeneration systems (methanol-power generation, hydrogen-power generation) are considered using coal as the basic fuel. The results showed that emergy evaluation indices are practical for comprehensively evaluating polygeneration systems and their sustainability, which is influenced by such factors as the joining mode of polygeneration and the technologies used. The sustainability of polygeneration systems, which work on an appropriate ratio of fuel-to-electric power basis, is higher than that of singular production systems.
