A tubular reactor for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert with cup-shaped structures having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.

Tubular reactor with jet impingement heat transfer

A tubular reactor and method for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.

A method and a reactor made by a method for increasing heat transfer from a heat source outside a vessel to the fluid inside the vessel are characterized by expanding a structure within the vessel toward the inner vessel surface so as to decrease the spacing between the structure and the vessel wall. The structure may be any of the various so-called structured packings, for example, ceramic honeycombs, metal honeycombs, plate stacks, and the like. The structure may comprise catalyst. The reactor provides high activity, low pressure drop, and high heat transfer. The reactor may be especially suitable for steam hydrocarbon reforming.

Reactor with expandable structure providing improved heat transfer

A process for generating synthesis gas wherein a reactant gas mixture comprising steam and a light hydrocarbon is introduced into a tubular reactor comprising a catalyzed structured packing at higher inlet mass rates than conventional tubular reactors containing random packing catalyst pellets or catalyzed structure packing.

Process for generating synthesis gas using catalyzed structured packing

This invention relates to process for carrying out gas-liquid reactions such as those employed in the hydrogenation or oxidation of organic compounds. In the catalytic reaction of a liquid reactant and a gaseous reactant to form a product, the improvement which comprises: pressurizing a liquid reactant and, then, introducing the resultant pressurized liquid reactant to a liquid motive gas ejector wherein it is mixed with the gaseous reactant. The mixture is passed to and reacted in a monolith catalytic reactor. The products are removed from the monolith catalytic reactor at a reduced pressure and, then introduced to a tank. The unreacted materials in the reaction product then are recirculated back to the ejector.

Gas-liquid reaction process including ejector and monolith catalyst

This invention relates to an improvement in a process for hydrogenating a nitroaromatic composition namely dinitrotoluene by contacting the dinitrotoluene with hydrogen in a reactor employing a monolith catalyst system. Broadly the improvement resides in the continuous, essentially solventless, adiabatic hydrogenation of dinitrotoluene to toluenediamine in a plug flow reactor system incorporating the monolith catalyst. The process generally comprises the steps: introducing a feedstock comprised of dinitrotoluene and reaction product components continuously into the reactor and said feedstock having less that 30% by weight of a solvent, carrying out the hydrogenation of dinitrotoluene to toluenediamine under adiabatic conditions; and, continuously removing hydrogenated reaction product from the reactor.
