Abstract

Chemical formulations for chemical products can be represented by digital formulation graphs for use in machine learning models. The digital formulation graphs can be input to graph-based algorithms such as graph neural networks to produce a feature vector, which is a denser description of the chemical product than the digital formulation graph. The feature vector can be input to a supervised machine learning model to predict one or more attribute values of the chemical product that would be produced by the formulation without actually having to go through the production process. The feature vector can be input to an unsupervised machine learning model trained to compare chemical products based on feature vectors of the chemical products. The unsupervised machine learning model can recommend a substitute chemical product based on the comparison.

Abstract

Disclosed herein are methods of improving the life of high selectivity, silver catalysts for making ethylene oxide. Ethylene and oxygen are reacted over the high efficiency catalyst with at least one organic chloride modifier, and during a catalyst aging period of no less than 0.03 kt ethylene oxide/cubic meter catalyst, the overall catalyst chloriding effectiveness never exceeds an efficiency-maximizing optimum overall catalyst chloriding effectiveness value that corresponds to a reference feed gas composition and a set of reference reaction condition values. Reaction temperature and/or feed gas oxygen concentration are adjusted to obtain or maintain a desired value of an ethylene oxide production parameter. Once the reaction temperature and/or oxygen concentration vary by a specified amount from their respective reference values in the set of reference reaction condition values, the overall catalyst chloriding effectiveness is changed to account for a shift in the optimum (efficiency-maximizing) value.
