Abstract:
PURPOSE: A honeycomb rotor type VOCs removal system with horizontally polarized microwave radiation is provided to remove a high concentration VOCs gas in a short time by constantly supplying a heat source. CONSTITUTION: A honeycomb type adsorption rotor comprises an absorbent. A driving device rotates the honeycomb type adsorption rotor. A waveguide (5) is installed in front of a microwave injection device (6). A recycled air purge part (17) purges air including VOCs components to the outside. A cold air injection part (15) supplies cold air to a cool region. [Reference numerals] (AA,DD,GG) VOC_s + air; (BB,EE,HH) Air; (CC,FF) Heated air
Abstract:
A membrane reactor for a fuel cell is provided to obtain excellent hydrocarbon/steam reforming reaction efficiency, hydrogen recovery ratio and CO removal ratio by simultaneously performing a hydrocarbon/steam reforming reaction and a CO removal reaction, and a hydrogen production method using the membrane reactor is provided. In a membrane reactor comprising a raw material gas supply part for injecting hydrocarbon and steam, a membrane, and a gas exhaust part for exhausting gas that permeates the membrane, a membrane reactor enabling a hydrocarbon/steam reforming reaction and a CO removal reaction to be performed simultaneously includes: a catalyst for hydrocarbon/steam reforming reaction mounted on the raw material gas supply part; a catalyst for CO removal mounted on the gas exhaust part; a membrane which is mounted on an inner part of the reactor, and has mesopores with a pore size range of 2 to 100,000 nm formed therein, wherein the hydrocarbon/steam reforming reaction and a water gas reaction are simultaneously performed within one membrane reactor. The hydrocarbon is selected from methanol, ethanol, methane, dimethyl ether, and gasoline.
