Title: The Innovative Contributions of Homer R. Johnson
Introduction
Homer R. Johnson is a notable inventor based in Charleston, SC (US). He has made significant contributions to the field of materials science, particularly in the activation of carbonaceous materials. With a total of 4 patents to his name, Johnson's work has had a lasting impact on various industrial processes.
Latest Patents
One of Johnson's latest patents is a "Process for Activating Carbonaceous Material." This patent describes an improved method for activating carbon in a fluidized bed system. The process involves continuous activation at temperatures ranging from 1,000°F to 2,200°F, utilizing a specific composition of fluidizing gases. The thermal energy required for activation is partially supplied by the sensible heat of the fluidizing gases, which contain excess oxygen. This oxygen reacts exothermically with the products of the activation reaction, contributing the necessary heat to maintain bed temperatures. Additionally, the process may introduce secondary excess air above the bed to further enhance the activation reaction.
Another significant patent is the "Two-Step Process for Conditioning Sized Coal and Resulting Product." This patent outlines an improved two-step fluid bed process for conditioning high volatile bituminous coal. The coal is first crushed and sized for fluidization, followed by a first treatment under oxidizing conditions at temperatures below the fusion point of the coal. This is immediately succeeded by a second treatment in a non-oxidizing atmosphere. The resulting coal particles possess a volatile content of at least 15%, rendering them non-agglomerative when subjected to higher temperatures.
