Process for Converting Butanol into Propylene

Abstract

Process for selective the conversion of primary C4 alcohol into propylene comprising: contacting a stream (1) containing essentially a primary C4 alcohol with at least one catalyst at a temperature ranging from 150° C. to 500° C. and at pressure ranging from 0.01 MPa to 10 MPa conditions effective to transform said primary C4 alcohol into an effluent stream (2, 5) containing essentially propylene, carbon monoxide and di-hydrogen, said transformation of primary C4 alcohol comprising at least a reaction of decarbonylation and optionally a decarboxylation reaction, said at least one catalyst comprising a support being a non-acidic i.e. having a TPD NH3 of less than 50 preferably less than 40 μmol/g and optionally a non-basic catalyst i.e. having a TPD CO2 of less than 100 preferably less than 50 μmol/g.
