Abstract: Molecular sieve SAPO 34, a member of the new family of microporous silicoaluminophosphate crystal, was synthesized by using aluminium isopropoxide (AIP) as sources of aluminium , tetraethyl orthosilicate (TEOS) as sources of silicon and triethylamine (NEt3) as template. SAPO 34 catalyst was characterized by XRD, SEM, IR and EDX. Thermal stability of SAPO 34 molecular sieve were studied by TGA and DTA techniques, no structural collapse of samples was observed upon calcination up to 800℃. The experimental results indicated that SAPO-34 catalyst gave higher selectivity for light olefins. So using SAPO 34 catalysts, endothermic fuels is able to provide higher heat sink. It is shown that SAPO 34 catalyst is a effective catalyst for endothermic fuels.
