The present invention is a phosphorous modified zeolite (A) made by a process comprising in that order:

    selecting a zeolite with low Si/Al ratio (advantageously lower than 30) among H+ or NH4+-form of MFI, MEL, FER, MOR, clinoptilolite, said zeolite having been made preferably without direct addition of organic template;steaming at a temperature ranging from 400 to 870° C. for 0.01-200h;leaching with an aqueous acid solution containing the source of P at conditions effective to remove a substantial part of Al from the zeolite and to introduce at least 0.3 wt % of P;separation of the solid from the liquid;an optional washing step or an optional drying step or an optional drying step followed by a washing step; a calcination step.
