摘要: 1,158,637. Pyrolytic deposition of carbon. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 15 Aug., 1967 [25 1966], No. 38264/66. Heading C1A. [Also in Division G6] In a high temperature process for the pyrolytic carbon or carbon-containing substance from gas phase, said being introduced into apparatus through an injection orifice, agent is to initiate exothermic reaction additional and compatible with reaction. The preferably oxidizing agent, e.g. CO 2 , air, oxygen, water vapour, may be either pyrolysis elsewhere. Examples describe methane methane/ argon at 1800 2300‹ C. on fluidized beds refractory oxide (e.g. ThO /UO ) carbide particles. Tumbling furnaces also used.
