The alkylation reaction of benzene with 1 -dodecene was investigated in a liquid -solid circulating fluidized bed reactor (LSCFBR)using zeolite HY as catalyst. The conversion of 1 -dodecene
the apparent reaction rate constant
the activity of catalyst and the product distribution in the LSCFBR were analyzed and the different performances in the LSCFBR and stirred tank batch reactor (STBR) were compared.
