Disclosed is a catalytic pipe for an endothermic catalytic reaction of a process medium, with an outer cladding tube which is tightly closed at its end sides by a first base and a second base. A rising pipe arrangement is arranged in the interior of the cladding tube and is connected, in the vicinity of the first base, with an outlet which is guided outward for the product resulting from the catalysis of the process medium. According to the invention, the rising pipe arrangement is formed by a plurality of line strands which end in a collector which is connected to the outlet for the product.

Process and installation for generating electrical energy

Apparatus for providing heat to a reaction chamber in which an endothermic reaction is performed under utilization of hot smoke gas includes a barrier, preferably a tubular barrier at least partially enclosing the reaction chamber but being spaced therefrom; hot smoke gas is fed to a ring chamber outside of the barrier and caused to flow there along while losing some of its heat content until at a lower end of the barrier the flow of the cooled smoke gas is reversed and the gas is introduced into a gap between the barrier and the reaction chamber so that heat is transferred through the barrier from the hot smoke gas as it flows along the outside of the barrier to the gas as it flows in the gap for heating the reaction chamber in an essentially uniform manner.

Heating an endothermic process

A stream of process gas is indirectly heated in an elongated reaction chamber (1) with a longitudinal axis, a first end (12) and a second end (13) and defined by an outside shell (2) and a thermally conductive inner wall (4). The inner wall defines at least one recess or cavity (3) which extends substantially between the first and second end of the chamber and parallel to the longitudinal axis thereof. A process feed line (6) and a product-gas discharge line (7) are provided at opposite ends (12, 13) of the chamber. A heat conductive and heat resistant barrier (8) which defines an interior space extends coaxially with the recess or cavity (3) substantially along the entire length of the inner wall (4) and forms an annular space (9) therewith. A hot flue gas feed line (10) and a flue gas discharge line (11) is provided at one end (13) of the chamber. The hot gas feed line (10) leads directly into the interior space of the barrier (8) and the annular space (9) is in fluid communication with the interior space of the barrier (8) at the end (12) of the chamber which is opposite to the location of the hot flue gas feed line (10).

Apparatus and method for indirectly heating a gas

A reforming process for the production of hydrogen or synthesis gas is improved by a preparatory process including the preheating of gaseous hydrocarbons within a heat exchange zone into which water is sprayed to obtain concurrently evaporation of water and preheating of the water vapor as well as mixing of the hydrocarbon gases being preheated with the steam as produced, and preheating of the entire blend will continue prior to charging the reformed process.

An air lift fermentor comprising in combination a hollow cylindrical body, vertically located and subdivided into three zones by a pair of diaphragms parallel to the axis of said cylindrical body, the central zone of which is destined to fermentation of the liquor, and the two lateral zones serve for recirculating the liquor itself, after its passage through a heat exchanger and an air distributor, both located near the bottom of said cylindrical body.
