Abstract
A reactor (100) is provided which comprises an enclosure (1,2,3) which has along its longitudinal axis (4--4') a hot zone (1), a cold zone (2) and between the hot and the cold zone an intermediate zone (3) and which has at least one gas inlet tube (12,32). The reactor further comprises a heat-insulating plug (30) for being positioned in the intermediate zone (3) to prevent a gas-flow from the hot zone (1) to the cold zone (2) of the enclosure (1,2,3) and coupling means (13,102;33,36) for transmitting gas from the gas inlet tube (12;32) into the hot zone (1). The use of the heat insulating plug (30) prevents deposition of unwanted material on the walls of the cold zone (2) of the reactor.
