Title: Catalyst for steam-reforming and methanisation - consisting of impregnated sintered metal coating on a metal surface
Inventor: GOLEBIOWSKI ANDRZEJ
IPC: C01B3/40
Filed: 1975-11-24
Abstract: Catalyst bonded directly to a metal surface used for heating the reaction mixt. is made by (A) producing a highly porous metal sponge from powder by known sintering methods, (B) impregnating the sponge with salts and calcining to give >=1 non-reducible oxide (esp. Al2O3) and >=1 reducible oxide (esp. NiO) in combined amount not greater than the wt. of sponge, and (c) reducing the second oxide in the porous layer. The sponge layer is pref. made by >=2 sintering operations, with the finer powder bonded to the metal surface. Catalyst is used in steam-reforming of hydrocarbons, esp. methane, to CO/H2 mixts. and the reverse reaction for methanisation of CO/H2 mixts. Activity is at least as good as known catalysts on ceramic carriers, and thermal conductivity is much improved. The metal sponge gives high strength and adhesion e.g. to the metal walls of reforming reactor tubes. Recrystallisation of the active catalyst is prevented by the non-reducible oxide, which also determines the surface area.

Title: Annular diffuser for axial flow compressors - has downstream section divided into concentric rings allowing larger diffuser angle
Inventor: JOBSKI ROBERT DIPL ING
IPC: F04D29/54
Filed: 1976-02-19
Abstract: Diffuser has an outer conically tapering side and an inner side tapering conically the other way so that the space between them is an annulus whose cross section increases axially. The angle of the annular diffusing cone so formed is greater than 7 deg. At a point in the axial direction before that at which the boundary layer would separate an intermediate annular sheet is interposed between the inner and outer sides. It divides the annulus into two concentric diffusing passages with a combined angle. This enables the angle of the diffuser to be greater than would otherwise be possible without boundary layer separation.
