The invention relates to a material with high anti-explosivity and vaporization reduction, which is an alloy of aluminum, nano activated carbon or nano graphene and a plurality of other metal elements in the form of an engineered mesh (cylindrical forms—inner jacket) that represents 2% of the internal volume of the content of oil, its derivatives and gas. The material has high absorptivity and high absorptivity, suppresses the movement of gas particles and fumes, improves the flash point by 35%, the ignition temperature by 40% and reduces evaporation by 70%, thereby preventing the explosion of oil, its derivatives and gas upon exposure (fire, collision, static electricity, high heat, being struck by a projectile). Separately, the polymer sodium polyacrylate is added to crude oil to improve its properties and protect it from explosion.
