Introduction
Robert N. Miller is a notable inventor based in Allentown, PA (US), recognized for his contributions to the field of coal liquefaction. He holds a total of 5 patents, showcasing his innovative approaches to improving coal processing techniques.
Latest Patents
Miller's latest patents include a coal liquefaction process that utilizes pretreatment with a binary solvent. This improved process enhances thermal solvent refining or hydroliquefaction of non-anthracitic coal at elevated temperatures under hydrogen pressure. The method involves pretreating the coal with a binary mixture of an aromatic hydrocarbon and an aliphatic alcohol at temperatures below 300°C, which generally increases both coal conversion and oil yields. Another significant patent focuses on coal liquefaction with preasphaltene recycle. This system features a novel preasphaltene recycle from a supercritical extraction unit to the slurry mix tank. The recycle stream contains at least 90% preasphaltenes, along with unconverted coal and ash. This process results in the production of asphaltene materials that can be hydrotreated to create a substitute for No. 6 fuel oil, while also reducing hydrogen consumption.
