Abstract
A method is described for co-processing of ethanol and hydrocarbons from petroleum refining, which are introduced separately in two reaction zones of a reactor of a fluidized catalytic cracking unit. The process combines conversion of ethanol into ethene and conversion of hydrocarbons into other lighter hydrocarbon fractions, to produce ethene in quantities of 15 to 90 wt % in the fuel gas fraction obtained during the process.
