Not energy generation is <br />not established <br />based on Japanese and European experience. Itisa pyrolysis- related process where <br />i <br />little or no oxygen is injected into a reactor. Atypi oa unit is shown in Figure 8-11 . . <br />Electric current is passed through o series of torches at the bottom of avnaaotor, <br />which heat process gas (not shown) to a temperature in excess of5,OOO F.
