NOVELTY - Preparing graphene from biomass derivatives based on mechanochemical process involves preparing biomass sample, where industrial sample is selected from industrial and agricultural wastes containing lignocellulose and minerals, and biomass sample is cutting and grinding to obtain biomass particles. The biomass is pyrolysized in pyrolysis reactor to obtain biomass coke. USE - Method for preparing graphene from biomass derivatives based on mechanochemical process (claimed). ADVANTAGE - The method enables to prepare graphene from biomass derivatives based on mechanochemical process which has provides feasible way for processing of agricultural and industrial waste material. DETAILED DESCRIPTION - Preparing graphene from biomass derivatives based on mechanochemical process involves preparing biomass sample, where industrial sample is selected from industrial and agricultural wastes containing lignocellulose and minerals, and biomass sample is cutting and grinding to obtain biomass particles. The biomass is pyrolysized in pyrolysis reactor to obtain biomass coke. The pyrolysis of biomass coke is placed into pressure reactor, pressure in reactor pressure and pressure control to reached reaction time after the rapid pressure relief to obtain initial product of graphene. The original product of graphene is obtained in polar solvent for stripping a single layer of graphene, and repeatedly washed to obtain final product.
