Abstract: The invention relates to a method of producing a suspension of graphene particles and the corresponding suspension. The method of producing a suspension of graphene particles comprises the steps of: [a] depositing carbon on a substrate by means of CVD, where graphene particles are formed on the substrate partially covering it, [b] interrupting the deposition of carbon on the substrate before the surface of the substrate coated with graphene is more than 85% of the total surface of the substrate, [c] immersing the substrate in a liquid, and [d] separating the graphene particles from the substrate such that they are suspended in the liquid. At least 50% of the graphene particles in the suspension are monolayer particles.

Abstract: A moving bed reactor system is provided. The system comprises at least one gas inlet, a distributor, a temperature control, a plurality of electrodes, and a spark control circuit. The spark control circuit drives the electrodes and generates a multi-arc discharge when the system is loaded with particles and a gas at approximately atmospheric pressure or greater is being pumped through the system. The multi-arc discharge is useful to create activated species which may improve the rate of a chemical reaction taking place in the moving bed reactor system.
