Abstract

Carbon pillared clay was prepared from bentonite modified by C₁₉H₄₂BrN and C₁₀H₁₆CIN and then characterized.Surface morphology of the sample was observed by Scanning Electron Microscope(SEM),the bore properties including the ratio surface,bore structure and bore path distribute of material were analyzed by ASAP2020 model test instrument of surface area and pore width,slice layer structure of carbon pillar clay was studied by Japanese D/PC MAX-2200 diffraction instrument.The DSC and TG curvs of carbon pillared clay were analyzed.The results indicated that the micro feature of carbon pillared clay were needle slice,the average bore diameter decreased,and the ratio surface enlarged,the mainly structure of carbon pillared clay was two-dimensional aperture formed by carbonized large particles,the hot stability of organic clay can be significantly improved with heat treatment.

Key words
