Title: Nathan A. Chapman: Innovator in Coal Agglomeration Technology

Introduction

Nathan A. Chapman is a notable inventor based in Santa Barbara, California. He has made significant contributions to the field of coal processing, particularly in the agglomeration of ultra-fine coal particles. With a total of two patents to his name, Chapman is recognized for his innovative approaches to enhancing the efficiency and effectiveness of coal utilization.

Latest Patents

Chapman's latest patents focus on a method for preparing agglomerates of ultra-fine coal particles. This method involves mixing a film forming agglomeration aid (FFAA) with ultra-fine coal particles to create a coated product. The FFAA has a lower surface energy compared to the coal particles, which aids in the agglomeration process. The mixture contains less than 3% FFAA by weight of the ultra-fine coal particles on a dry basis. The resulting agglomerates are formed through techniques such as vibration, pelleting, and briquetting, achieving a size of at least 2 mm. The ultra-fine coal particles used in this process have a particle size of less than 100 micrometers, and the agglomerates exhibit a tumbler test friability of less than 3%, as well as a drop shatter friability of less than 3%.
