发明名称 Process for the production and treatment of graphite powders
摘要 The disclosure relates to processes for the production and thermal treatment of carbon material, in particular, graphite powders, in an Acheson type oven, using a functional filler comprising graphitic material in particulate form allowing electrical current to flow through the charge. The particulate form of the filler allows greater flexibility and can be used to control the degree of direct and indirect heating, resulting in more uniform products. Such graphite materials may typically be employed as an additive in polymers, batteries, or other applications.

主权项 1. A process for thermal treatment of carbonaceous material, the process including: heating a charge including the carbonaceous material, wherein, in addition to the carbonaceous material to be treated, a functional filler comprising graphitic material in particulate form is added to form a mixture for allowing electrical current to flow through the charge, and wherein at least 5% by weight of functional filler is present in the mixture; and separating the carbonaceous material from the functional filler following treatment of the carbonaceous material via classification.
