Abstract:A more simple and general method to identify the Alatom positions in zeolite is given in this article.A program which is ableto give all of the mequuival ent Si-Al distribution uuder a Si/Al ratio in oue of basic framework FAU has been established.A model structnre unit have been selected for calculation of heat of formation AfH.The calculation hasbeenper for medwith PM3 mecthod.The term SDR is defined for snm of the reciprocal of distance among Al atoms.The linear relation between AfH and SDR has been found.
Keywords:Zeoite  Alatomsites  Computersimulation
