Abstract: In a process for producing hydrogen or syngas by methanol cracking, whereby methanol is catalytically decomposed into hydrogen and carbon monoxide in an endothermal reaction, said reaction takes place in a reactor with direct inductive heating in the reaction zone. The heating is obtained by passing an alternating current through a metallic coil located inside the reactor or by using induction heated catalyzed hardware in the shape of a ferromagnetic structure, which is coated with an oxide impregnated with the catalytically active phase.

Abstract: In a process for co-production of ammonia and methanol, the outlet stream from the reformer is split into two parts, one of which is subjected to shift, carbon dioxide removal, methanation, compression and ammonia synthesis, while the other part is compressed and fed to a once-through methanol synthesis section. Methanol is withdrawn from the methanol synthesis section, and the remaining effluent from said section is divided into two streams comprising hydrogen, of which one is fed to the shift section, while the other is recycled to the desulfurization unit. This way a favourable co-production method is obtained because recycle hydrogen for the desulfurization is provided, and furthermore a compression step is avoided.

Abstract: A catalyst for the dehydrogenation of alkanes to alkenes comprises a catalytically active material supported on a carrier, wherein the catalytically active material is a metallic sulfide (MeS) comprising Fe, Co, Ni, Cu, Mo or W or any combination of two or more metals selected from Pb, Sn, Zn, Fe, Co, Ni, Cu, Mo and W. The catalyst is regenerated in several steps. The dehydrogenation is carried out at a temperature between 450 and 650° C. and a pressure from 0.9 bar below ambient pressure to 5 bar above ambient pressure.

Abstract: A float valve for a chemical reactor has a central pipe which glides around a liquid transfer pipe when a liquid level rises and falls, thereby opening for fluid transfer through liquid transfer apertures in the transfer pipe when the liquid level is rising and shutting off for fluid transfer when the float lowers and seals against a sealing ring placed on the transfer pipe below the liquid transfer apertures.
