Patent DE-4028853-A1 (DE)
Inventor: MANOLESCU MIRCEA TUDOR
IPC: C10J/
Filed: 1990-09-11
Abstract: The invention concerns a process and device for gasifying liquid and/or fine-particulate solid materials and/or for reforming a gas, with the addition of a gasification agent, in a reactor (1). In this process, the heat is supplied by heat-carrier particles which are heated in a heater (5) by combustion gases produced in a combustion chamber (3), then passed, flowing in the opposite direction to the material being gasified/gas being reformed plus gasification agent, through the reactor (1), and subsequently fed back in an essentially closed circuit to the heater (5) for reheating. The invention calls for the particles and the combustion gas to form a fluidized bed above at least one grid (34, 34a, 34b, 34c, 34d, 34e) fitted in the heater (5). The particles flow out of the heater (5) into the combustion chamber (3) next to it where they form, together with the combustion gas, a fluidized bed, subsequently passing out of the combustion chamber (3) through an overflow pipe (7, 7') which carries them into the upper zone of the reactor (1). The passage of the particles through the overflow pipe (7, 7') compresses the particles, which prevents the gaseous products produced in the reactor (1) from escaping through the pipe. In the reactor (1), the particles form one or more fluidized beds together with the material being gasified and/or gas being reformed.
