Ring shaped radial arrayed fluidized bed membrane reactor

Abstract

The invention discloses an annular radially arranged fluidized bed membrane reactor, which comprises an outer tube, an inner tube, a palladium membrane module, an exhaust filter, a feed air distribution plate, a support plate and a bellows; the inner tube is located at the center of the outer tube , an annular space is formed between the inner and outer tubes, and multiple palladium membrane modules are arranged radially between the inner and outer tubes. The lower end of the material cloth wind plate, and the bellows are arranged under the support plate; the catalyst is filled in the annular space annular area between the inner pipe and the outer pipe; the tail gas filter is arranged on the top of the reactor, and its outlet pipe passes through the top of the reactor. The fluidized bed membrane reactor has sufficient membrane surface area per unit volume of the reactor volume, and the palladium membrane modules are easy to install and arrange, and can destroy the equilibrium conversion rate of the hydrogen production reaction, making the chemical reaction balance of the reversible hydrogen production reaction toward The direction of hydrogen production is shifted, and high-purity hydrogen can be produced in one reactor.

Description

Technical field [0001] The invention relates to a fluidized bed membrane reactor, in particular to a ring-shaped radially arranged fluidized bed membrane reactor. Background technique [0002] Hydrogen energy, as a clean, efficient, safe, and sustainable energy source, is regarded as the clean energy with the most development potential in this century. It is also regarded as an effective alternative energy source for solving the greenhouse effect and improving energy utilization. Natural gas steam reforming (SMR) technology is a technology commonly used in industry for the production of hydrogen and synthesis gas. This reaction is a strong 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 2.5-3.5 MPa. [0003] The most commonly used reactor in the industry is a fixed-bed tubular reactor, which provides the heat required for the reaction through external...

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
