Calcination of microporous molecular sieve catalysts

A process to make a catalyst comprising:

• (i) providing a microporous crystalline metallosilicate having a Constraint Index of 12, or 10, or 8, or 6 or less, (ii) a binder, (iii) a Group 1 alkali metal or a compound thereof and/or a Group 2 alkaline earth metal or a compound thereof, (iv) a Group 10 metal or a compound thereof, and, (v) optionally a Group 11 metal or a compound thereof;
• calcining in a first calcination step the combination of materials before the addition of the Group 10 metal or compound and optional Group 11 metal or compound thereof;
• adding the Group 10 metal or compound thereof and then calcining in a second calcination step prior to addition of the optional Group 11 metal;
• adding the optional Group 11 metal or compound thereof and then calcining in a third calcination step wherein calcining includes heating the catalyst to temperatures of greater than 500° C. in the first calcination step and includes heating the catalyst to temperatures of greater than 400° C. in the second calcination step and includes heating the catalyst to temperatures of greater than 500° C. in the third calcination step.
