摘要：
The activities of nickel supported on SBA-15 catalysts which were prepared by pretreatment with ammonia/water vapour were investigated by hydrogenation of naphthalene Comparing with the un-pretreated catalysts the pretreated catalysts exhibited significant activity and naphthalene conversion was improved approximately 100% over the un-pretreated catalysts The formation of NH4NO3 during pretreatment which helped to reduce NO2/O-2 generation thus enhancing the dispersion of NiO was considered to be the main reason for the increased Ni-0 dispersion and the enhanced activity of the catalyst pretreated with ammonia/water vapour (C) 2010 Elsevier B V All rights reserved
