For the history of becoming the first production of contact anthraquinone in the Soviet Union. Part 2. Development and implementation of anthraquinone production by anthracene oxidation with atmospheric oxygen in a fluidized bed of catalyst

Abstract

Start of the first Soviet industrial plant production of anthraquinone
(600 tons/year) by anthracene oxidation by atmospheric oxygen in a fixed catalyst bed was successfully implemented in 1965 at Rubezhansky chemical plant. USSR Ministry of Chemical Industry leaders decided to establish an industrial plant anthraquinone production (600 tons/year) by anthracene oxidation in a fluidized catalyst bed, based on the experience of production realized in Czechoslovakia to choose the most effective method for the industrial production of anthraquinone . This plant started to produce in 1972. Description of the preparation of the catalyst of the Czechoslovak method, the procedure and results of the new installation are given in this article. Comparative analysis of the two methods of production of  anthraquinone (fluidized and fixed bed ) showed that the degree of feed conversion by both methods are very similar, but the stability of the installation systems with fixed bed catalyst is more preferable. Process with a fixed catalyst bed to be used when creating a subsequent production of anthraquinone in the USSR. Unfortunately , these projects could not be implemented.
