A reformer tube for producing synthesis gas by steam reforming of hydrocarbon-containing input gases is proposed where

Corrosion-protected reformer tube with internal heat exchange

A device for measuring the internal temperature of a reforming tube including a first structure having an axial part of tubular shape positioned in the lengthwise direction of a reforming tube and a radial part projecting radially towards the central axis of the reforming tube, a second structure of oblong shape having at least one thermocouple made of welded Nicrosil/Nisil conductors arranged longitudinally against the axial part and radially against the radial part, and an outer sheath enveloping the first structure and the second structure.

Device for measuring the inner temperature of a reforming tube

A reformer tube for producing synthesis gas by steam reforming of hydrocarbon-containing feed gases, in which a structured stream reforming catalyst is used, is proposed. According to the invention, a heat exchanger tube is arranged in the interior of the structured catalyst, with the feed gas stream flowing firstly through the structured catalyst and subsequently in countercurrent through the heat exchanger tube. This improves the heat exchange between the synthesis gas product stream and the structured catalyst and the feed gas stream flowing through it, especially in the radial direction.

Reformer tube having a structured catalyst and improved heat balance

The invention relates to an exchanger-reactor comprising at least three stages with at least one stage comprising both: millimetric channels at least partially covered with a catalyst for stimulating a steam reforming reaction, and millimetric channels at least partially covered with a catalyst for stimulating a water gas reaction.

Exchanger-reactor performing steam reforming and water gas reactions for the production of hydrogen

Process for depositing a corrosion-protection coating on at least one portion of the surfaces of a metallic substrate having at least one cavity with an equivalent diameter e&#x3c;2 mm and a length/width ratio of greater than 150, using an aqueous suspension comprising powder of the metal to be deposited on the substrate combined with an agent for protecting the surface of the metal powder, a diluent, and at least one additive, the particles of the suspension each having an equivalent diameter d such that d&#x2264;e/10.
