Chlorine dioxide (ClO) is produced by apparatus and methods wherein a ClOgas produced in the apparatus is quickly introduced into a fluid stream to be treated with said gas. To this end, the apparatus has an interior chemical reaction chamber which houses an internal fluid flow tube having a fluid impervious upper section and a porous lower section that respectively define two zones within the interior chemical reaction chamber.

Apparatus and methods for producing chlorine dioxide

The invention concerns a process for the production of chlorine dioxide comprising generating chlorine dioxide in an aqueous reaction medium in a reaction vessel maintained at super-atmospheric pressure, withdrawing gaseous chlorine dioxide from said reaction medium, bringing withdrawn gaseous chlorine dioxide to an aqueous absorption medium and withdrawing gaseous chlorine dioxide from said absorption medium.

Process for the production of chlorine dioxide

The present invention relates to a process for the removal of lignin from lignocellulose containing material comprising treating the lignocellulose containing material prior to a high-yield pulping process with a delignifying gas comprising gaseous compounds comprising at least one oxygen atom such as chlorine dioxide containing gas.

Process for removal of lignin from lignocellulosic material

The present invention relates to a process for the removal of lignin from lignocellulose containing material comprising treating the lignocellulose containing material prior to a chemical pulping process with a delignifying gas, wherein the gas comprises chlorine dioxide.

Process for gas phase pretreating of lignocellulosic containing material

The invention relates to a process for production of an alkaline hydrogen peroxide solution and an acidified alkali metal salt solution containing chlorate in an electrochemical cell including an anode compartment provided with an anode and a cathode compartment provided with an oxygen reducing cathode. In the cathode compartment an aqueous alkali metal hydroxide and hydrogen peroxide is formed, wherein the molar ratio MOH:H,O,for the net production thereof is maintained from about 0.1:1 to about 2:1. Also a process for simultaneous production of chlorine dioxide is disclosed.
