Title:
【発明の名称】直接合成による過酸化水素の製造法
Document Type and Number:
Japanese Patent JP2002511378
Kind Code:
A
Abstract:
An aqueous solution of hydrogen peroxide is produced by direct synthesis from hydrogen and oxygen in the presence of a heterogeneous catalyst. According to the invention, a gas mixture comprising H2 and O2, essentially saturated or supersaturated with water (=containing fog) is fed into a reactor containing the catalyst. The volume ratio of the gas mixture fed in (standard liters per hour) to liquid removed (liters per hour) is adjusted to a value equal to or greater than 15,000, especially 20,000 to 50,000, and the gas mixture leaving the reactor is recycled after replenishment with H2, O2, and H2O vapor. Solutions with high H2O2 concentration can be obtained according to the invention without additional concentration.
