In　this　study,　a　series　of　FeSAPO-44　molecular　sieves　are　synthesized　by　a　facile　like-dry-gel　method.　The　untreated　bauxite　is　used　as　the　source　of　Al,　Si,　while　Fe　element　is　retained　as　the　acid　site.　Rice　husks　are　provided　for　auxiliary　Si　source　together　with　Si-sol　to　balance　Al/Si　ratio,　and　its　cellulose　plays　a　role　in　favoring　Fe　of　bauxite　into　the　framework　of　molecular　sieves.　The　referred　sample　derived　from　pseudo-boehmite　confirms　rice　husk　facilitates　Fe　enter　the　skeleton.　The　referred　sample　synthesized　from　ethyl　cellulose　further　affirmed　the　function　of　cellulose.　The　crystal　structure,　surface　area,　pore　diameter,　surface　properties　and　acidity　of　samples　are　systematically　characterized.　Furthermore,　the　obtained　FeSAPO-44　molecular　sieve　from　natural　source　of　bauxite　and　rice　husk　is　used　as　a　carrier　to　support　Mo　for　the　hydrocracking　of　Karamay　super　heavy　oil,　which　shows　a　feasible　practical　application.
