Non-catalytic reforming reactor and technology thereof

Abstract

The invention discloses a non-catalytic reforming reactor and a technology thereof. The reactor comprises a heat exchange area, a mixing area and a reforming reaction area. The heat exchange area is in an outer layer, and an inner layer is the mixing area and the reforming reaction area. The mixing area is positioned below the reforming reaction area. The heat exchange area is constructed as an end-to-end Swiss-roll-type structure layer by layer through a direct metal laser sintering technology. The heat exchange area is capable of, through air, realizing heat exchange with opposite-type flowof a product. The mixing area is a detachable screw-type pipeline structure. The reforming reaction area is a cylinder structure, and positioned above the mixing area. An air outlet of the heat exchange area is communicated with an air inlet of the mixing area. An outlet of the mixing area is communicated with an inlet of the reforming reaction area. An outlet of the reforming reaction area is communicated with a product inlet of the heat exchange area. The reactor avoids using a catalyst. An inlet reactant of the heat exchange area is the air, so low-energy efficient output is realized. The reactor is capable of improving a reforming productive rate as well as responding to the call of green chemistry.

Description

technical field [0001] The invention relates to a non-catalytic reforming reactor and its technology, in particular to the reforming of methane-rich gas produced by hydrocarbon gas liquid fuel, common biomass pyrolysis gas, coking plant, chemical fertilizer plant, oil refining and coal mining, etc. whole device. Background technique [0002] Partial oxidation is an easy way to convert high energy density hydrocarbon fuels (propane, natural gas, gasoline, JP-8, etc.) into syngas, which can easily be used by solid oxide fuel cells (SOFC) to generate electricity, or Further purification is used for high purity hydrogen generation. Since the partial oxidation reformate retains most of the chemical energy, there are some problems in how to utilize this chemical energy. [0003] Catalytic methods have several disadvantages for reforming hydrocarbon fuels. Catalysts also face challenges when fuels contain high concentrations of sulfur species. Sulfur can poison many catalysts, ...

But the disadvantage of its feeder is that the complex design of the injection device requires complex mechanical and electronic features for control, which undesirably increases the cost

Chinese patent 200810012601.9 discloses a method for removing tar and coke in the process of pyrolysis and gas and a method for reforming combustible gas. By using integral heat storage honeycomb ceramics as a carrier and carrying a catalyst, the conversion and reformation is carried out under the action of an oxidant. clean, but it is necessary to remove the tar and coke attached to the porous ceramic surface, which increases the cost and reduces the production efficiency
