Abstract
the Egyptian government will fing million acres. millions of tons of |i millions of tons of lignocellulosic residue represent about 70% of toy to work on agricultural Saws mixture (ASM) 11lignocellulosic substrate. Lignocelluloses showed anaerobic digestion (AD) because of 5 Sofie for methane produ Before the use of ASM in anaerobic digest] =o auger content and biodegradability ane production, a pretreatm e carried out for many reasons such as decre ce Fa b as decre g cellulose crystallinityaddition, unlike sulfuric acid, hydrolysis activity of SOsH group bonded to graphene doesn’t decrease with reaction time, because of the hydrophobic properties of graphene, which eliminate the chance of SOsH hydration [7-9]. All the previous properties qualified graphene based solid carbocatalyst to be our perfect choice for the pretreatment of ASM. Here in, we are going to synthesis graphene by a green method that depends on an eco-friendly raw material that is agricultural waste.
