| Abstract: | The presence of urea during the gelling of AlPO4–Al2O3 catalysts (AlPO4/Al2O3 weight ratio =3) has been studied with respect to its effect on the porous texture and surface acidity of the resulting gels. An increase in pore volume and mean pore radius with no modification in surface acidity is found when the AlPO4–Al2O3 catalyst is modified by the addition of 5 mol% urea in the AlPO4 solution.
