Title
A facile approach to improve the quality of diatomite as sulfuric acid catalyst support
Abstract

•High-energy electron beam (HEEB) irradiation was used to modify diatomite.•HEEB irradiation could effectively improve the pore size distribution of diatomite.•Catalytic efficiency of the catalyst based on the treated diatomite increased.•Etching, Coulomb explosion and thermal effects were the main modification mechanism.

High-energy electron beam (HEEB) irradiation, a facile modification approach, was applied to modify the pore size distribution of diatomite and improve the quality of diatomite as a catalyst support. The results demonstrated that HEEB irradiation modified the pore size distribution of diatomite due to etching, Coulomb explosion and thermal effects. The BET specific surface area, X-ray diffraction and catalytic performance results indicated that pore structure modification improved the micro-properties of diatomite and the catalytic efficiency of catalysts prepared from treated diatomite.
