A processing device and processing method that can perform processing of a starting material fluid while favorably controlling the processing temperature of same. The processing device includes: a processing member that leads in the starting material fluid and processes same therewithin; and a processing tank that houses the processing member and retains the processed processing products. The processing member includes: a minute duct provided therewithin and causes the flow-through of the starting material fluid; and a heat medium duct that causes the flow-through of a heat medium having a different temperature from that of the starting material fluid flowing through the minute duct. The minute duct and the heat medium duct are separated from each other so that heat exchange is possible between the starting material fluid and heat medium flowing through.

The flow passage structure comprises: a plural number of ceramic flow passage layers laminated with one another, inside of which a flow passage is formed; two outermost layers disposed on respective sides of the plural number of flow passage layers in a lamination direction where the flow passage layers are laminated; an outer elastic sheets made of an elastic body, which is interposed between each of the outermost layers and the flow passage layer adjacent thereto; and a fastening member fastening the two outermost layers to each other, in a state that the two outermost layers sandwich the flow passage layers from both sides in the lamination direction.

A reformer suitable for micro-scale design has horizontal catalyst tube(s) passing through a baffled radiant section for convective and radiant heat transfer to the tube(s). To reduce the footprint and/or to facilitate field assembly a combustion chamber and convection section can be oriented transversely with respect to the radiant section; the tube(s) can be horizontal and/or include structured catalyst; and/or the combustion chamber provides flameless combustion or produces a flame without impinging on the tubes. Also, a skid frame-mountable version of the reformer; and a process for transporting, assembling, and/or operating the steam methane reformer.

Disclosed is a process for the catalytic thermal decomposition of ammonia into hydrogen and nitrogen by contacting ammonia at a temperature of at least 500 C. with a porous ceramic layer which comprises nickel. Also disclosed is a reactor for carrying out the process.

Catalytic and/or sorptive articles comprising a metal fiber felt, the metal felt having an array of metal fibers and voids and a catalyst composition and/or a sorbent composition disposed on the metal fibers and within the voids are described. Such articles can be highly effective towards the abatement of pollutants in exhaust gas streams from internal combustion engines.

A flow reactor for photochemical reactions comprises an extended flow passage (20) surrounded by one or more flow passage walls (22), the flow passage having a length and a light diffusing rod (30) having a diameter of at least 500 m and a length, with at least a portion of the length of the rod (30) extending inside of and along the flow passage (20) for at least a portion of the length of the flow passage (20).

A flow reactor fluidic module (12) includes a reactant fluid module (20) having an internal process fluid passage (22) and a first major planar outer surface (24a) and a thermal resistance R between the internal process fluid passage (22) and the first major planar surface (24); a thermal control fluid module (30) having an internal thermal control fluid passage (32) and a second major planar outer surface (34a); a holding structure (50) holding the reactant fluid module (20) and the thermal control fluid module (30); and a gap (25) separating the first major planar surface (24a) from the second major planar surface (34a). The gap (25) comprises an interchangeable or replaceable substance or sheet (26) having a thermal resistance G across the gap (25), wherein G is not equal to R.
