Self-heating type alcohol reforming hydrogen production micro channel reactor with micro-lug boss array structure

Abstract

The invention discloses a self-heating type alcohol reforming hydrogen production micro channel reactor with the micro-lug boss array structure. Three layers of platy reaction carriers are all provided with micro-lug boss array structures; an upper layer and a lower layer are single-side micro-lug boss array structures; a middle layer is a double-side micro-lug boss array structure; the micro-lug bosses are arranged in the mode of parallel array; the three layers are cascaded to form a reaction channel with an inlet of 90 degrees; both ends of the channel are respectively provided with connector lugs; the gas inlet is provided with a detachable adapter and an outlet is provided with a fixed-type adapter. An upper layer channel is a catalytic reforming hydrogen production channel, and a lower layer channel is a combustion channel. The two layers of channel structures both adopt an open structural type being beneficial for the sediment of the catalytic coating. Fuel gases such as hydrogen and the like are combusted in the combustion channel and generate lot of heat which is transferred into the catalytic reforming hydrogen production channel by the middle layer of the reactor so as to meet the requirement of the steam reforming hydrogen production reaction; the reactor can produce hydrogen in a self-heating type. The invention increases the specific volume of the reactor and increases the yield of the alcohol reforming hydrogen production.

Description

technical field [0001] The invention relates to a microchannel reactor for hydrogen production by alcohol reforming, in particular to a self-heating microchannel reactor for hydrogen production by alcohol reformation with a micro-protrusion platform array structure. technical background [0002] Energy and resources are the source of human survival and development. With the development of society and economy, existing energy and resources are being consumed at an increasingly rapid rate. With the depletion of conventional resources such as oil and the increasingly serious environmental pollution, the development and utilization of clean and cheap fuel resources has attracted widespread attention from all countries. Among them, hydrogen energy has attracted widespread attention from various countries due to its advantages such as abundant resources, high calorific value, and no pollution, and its application is becoming more and more extensive.
