Patent ID: 8450233

Claim:
A catalyst composite comprising: at least 0.5% by weight of at least one metal salt, which is stable under temperatures of 200 to 700° C. and pressures of 5 to 5000 kPa, wherein the metal salt is selected from the group consisting of Mg 2 B 2 O 5 .H 2 O, CaMgB 6 O 11 .6H 2 O (hydroboracite), Ca 2 B 6 O 11 .5H 2 O (colemanite), Ca 4 B 10 O 19 .7H 2 O, Mg(BO 2 ).8H 2 O, Ca(BO 2 ).2H 2 O, BaB 6 O 10 .4H 2 O, CaSi 6 O 17 (OH) 2 (xonotlite), CaMg(Si 2 O 6 )x, Mg 2 (Si 2 O 6 )x, CaAl 2 Si 2 O 8 and combinations thereof; at least 10% by weight of molecular sieves which comprise 70 to 100% by weight of molecular sieves of at least one small pore aluminosilicate or small pore metalloaluminophosphate (MeAPO) molecular sieve and 0 to 30% by weight of molecular sieves of at least one medium or large pore molecular sieve comprising pore apertures defined by ring sizes of at least 10 tetrahedric atoms; wherein the at least one small pore aluminosilicate or small pore MeAPO molecular sieve comprises pore apertures defined by ring sizes of up to 8 tetrahedric atoms; wherein the at least one medium or large pore molecular sieve is selected from the group consisting of crystalline silicoaluminates, silicoaluminophosphates, mesoporous silicoaluminates and combinations thereof; wherein the MeAPO molecular sieve has predominantly a plate crystal morphology in which the width (W) and the thickness (T) are represented by the formula: W/T≧ 10.
