Ring shaped radial arrayed fluidized bed membrane reactor

Abstract

The invention discloses a fluidized bed membrane reactor arranged in cirque and radial shape, comprising an external pipe, an internal pipe, a Pd membrane component, a tail gas filter, a material inlet distributing plate, a supporting plate and a blast box; the internal pipe is arranged in the center of the external pipe; a cirque space is arranged between the internal pipe and the external pipe; a plurality of Pd membrane components are arranged radially in the cirque space between the internal pipe and the external pipe; the two surfaces of each membrane component are covered with Pd and silver alloy membrane; the supporting plate is arranged at the lower end of the material inlet distributing plate; the blast box is arranged below the supporting plate; activator is filled in the cirque area of the cirque space between the internal pipe and the external pipe; the tail gas filter is arranged on the top of the reactor; the outlet pipe of the tail gas filter passes through the top of the reactor. The fluidized bed membrane reactor leads the reactor container in unit volume to have enough membrane surface area; the Pd component is easy to be installed and arranged and can damage the balance conversion ratio of the hydrogen production reaction and leads the chemical reaction balance of the reversible reaction of hydrogen-production to move in the direction where the hydrogen is generated, thus generating the hydrogen with high purity in the same reactor.

Description

technical field [0001] The invention relates to a fluidized bed membrane reactor, in particular to an annular radially arranged fluidized bed membrane reactor. Background technique [0002] Hydrogen energy, as a clean, efficient, safe and sustainable energy, is regarded as the clean energy with the most development potential in this century, and is also regarded as an effective alternative energy to solve the problem of greenhouse effect and improve energy utilization rate. Natural gas steam reforming (SMR) technology is widely used in industry for the production of hydrogen and synthesis gas. The reaction is a strongly endothermic reaction and almost reaches equilibrium. The commonly used catalyst is a nickel-based catalyst, and the typical reaction temperature is 800-900°C and the pressure is 2.5-3.5MPa. [0003] The most commonly used reactor in the industry is a fixed-bed tubular reactor, which provides the heat required for the reaction by external heating or partial ...

AI Technical Summary

Problems solved by technology

The traditional reactor adopts a fixed-bed tubular reactor, which is bulky and has poor heat transfer effect, which is not suitable for the requirements of small-scale distributed hydrogen production
