Technology and the Main Technological Equipment of the Process to Obtain N4HNO3 with Nanoporous Structure

摘要

Porous ammonium nitrate (PAN) is an essential component of the industrial explosives without triton (ammonium nitrate/fuel oil, ANFO in particular) [1-3]. The quantity of fuel oil, efficiently absorbed and retained by PAN, depends on the sizes, the number, and the volume of pores, the configuration of the pores network on the surface and the pre-surface layers of a granule [4-6]. More specifically: ? A size of pores: a minimal size must be commensurate with the size of the fuel oil molecule. ? The number and the volume of pores must provide the proper absorbing ability of a granule. ? The configuration of the pores network: the surface straight pores available for the free penetration of fuel oil into a granule and the tortuous deep pores available for efficient binding of fuel oil inside a granule.
