A new structure for the surface complex of water on bridged hydroxyl sites is proposed which is stabilized by two hydrogen bonds. The energy for the formation of a surface hydronium ion is estimated to be 0.5f 20 kJ/mol. Tbis conclusion is based on quantum-chemical ab initio SCF calculations (DZP ba
The regeneration by coke combustion of a catalyst based on a SAPO-34 used in the transformation of methanol into ole®ns (ethene and propene) has been studied. It has been observed that coke combustion kinetics are strongly dependent on the nature of the coke (H/C ratio), which in turn is a consequen
