Title: The Innovations of Norman Schapiro
Introduction
Norman Schapiro is an accomplished inventor based in Sudbury, MA (US). He holds a total of 2 patents that showcase his contributions to the fields of coal processing and mineral engineering. His innovative approaches have made significant impacts in these industries.
Latest Patents
One of Schapiro's latest patents is the "Deashing process for coal." This process aims to reduce the ash content of coal with an initial concentration of inherent ash of approximately 0.25 w/o to approximately 3 w/o. The method involves swelling and wetting the coal with an alcohol solution, such as methanol, followed by deashing with a mineral acid solution, including hydrochloric and hydrofluoric acid. The resulting demineralized coal is then neutralized, washed, and dried for use in creating coal slurries with a very low ash content. Another notable patent is related to "Manganese nodule pelletizing." In this process, sodium ions are added to manganese nodules to convert the montmorillonite clay naturally occurring in the nodule material into a bonding agent for pelletization into spherical agglomerates. The addition of coking coal provides bonding strength after reduction, during which the clay bond is destroyed.
