The peculiarities of dehydration, thermal desorption and thermal degradation of organic templates in zeo- lite-like alumino- and silicoaluminophosphates of various structural types were found. The influence of pore size and acid centers on composition of the thermal degradation products, including the processes of the secondary synthesis of normal, cyclic and aromatic hydrocarbons, was established. The opportunity of passing of dehydration, oligomerization, cyclization, cracking, aromatization and alkylation reactions of hydrocarbons in zeolite-like phosphates was shown.

Key word thermal desorption, thermal degradation, template, zeolite-like aluminophosphates.
