Conversion of organic oxygen compounds and their mixtures on H‐ZSM‐5

The conversion of a number of alcohols, ethers, ketones, aldehydes, carboxylic acids, esters, and cyclic compounds and their mixtures on H‐ZSM‐5 at 673 K was investigated. These compounds can be easily converted to aromatic hydrocarbons if the C/H ratio of the molecule fragment, remaining after elimination of oxygen as water, is less than 0.62. At higher C/H ratios, coking of the catalyst increases, thus reducing its lifetime, a difficulty which can be overcome by hydrogenation of these compounds prior to their conversion over H‐ZSM‐5. A procedure is proposed for converting at least a part of organic waste chemicals to valuable products instead of burning them.
