Method of preparing pore-adjustable carbon molecular sieve by heavy oil binary activation and application thereof

Abstract

A method of preparing a pore-adjustable carbon molecular sieve by heavy oil binary activation and an application thereof are provided. The method includes: mixing heavy oil with a binary activator and leaving the mixture to stand and then forming a carbon-containing precursor mixture; where the binary activator is calcium citrate and potassium oxalate; performing pyrolysis activation on the carbon-containing precursor mixture under inert atmosphere, and cooling the mixture after pyrolysis to obtain a biological activated carbon; washing and drying the biological activated carbon to obtain a carbon molecular sieve. The method and the application thereof have the advantages of greenness, environmental protection, convenient process and efficient production; the prepared carbon molecular sieve has developed pore structure and centralized pore size distribution, having good adsorption characteristics, having broad application prospect in water treatment, and realizing the comprehensive disposal of the resource utilization of the disused heavy oil and dye wastewater.
