Preparation and catalytic behavior of biomorphic calcium oxide/carbon solid base materials

摘要: Using plant materials as templates is a convenient and low-cost route to prepare solid base catalysts with high specific surface area. In this study, series of biomorphic calcium oxide/carbon have been prepared via an in situ transformation technique using rice grains template carbon precursor. The resulting CaO/carbon are spindly shaped show area strong basicity. the methylation cyclopentadiene, these exhibit higher catalytic performance than MgO/carbon CaO by directly calcining Moreover, regeneration deactivated catalyst studied, steam or CO2 treatment at temperature found be very effective for supported catalyst, can even promote activity. A possible mechanism deactivation has proposed.
