ABSTRACT:
A reactor tube for a high temperature chemical reactor having a precisely controllable porosity comprises a plurality of layers of a fabric of a fibrous refractory material such as carbon or graphite cloth. Difficulties connected with the handling of carbon cloth, which has an extremely high coefficient of friction, are substantially eliminated by winding the cloth on a mandrel to form the reactor tube. After winding, the mandrel is contracted, allowing its removal without damaging the inside surface of the tube. Heating elements for the high temperature chemical reactor are also formed by winding carbon cloth on a mandrel. A preferred embodiment of the reactor contemplates that a plurality of such heating elements be positioned radially outwardly of the reactor tube.
