Title: Jerzy S. Janiak: Innovator in Coal Processing Technologies
Introduction
Jerzy S. Janiak is a notable inventor based in Edmonton, Canada. He has made significant contributions to the field of coal processing, particularly in the removal of pyritic sulfur from bituminous coals. With a total of 2 patents to his name, Janiak's work has implications for improving the quality of solid fuels.
Latest Patents
One of Janiak's latest patents is titled "Process for removing pyritic sulfur from bituminous coals." This innovative process involves grinding the feed coal and subjecting it to micro-agglomeration with a bridging liquid containing heavy oil. The method allows for the separation of micro-agglomerates, which are then washed with water to remove suspended pyritic sulfur. In a further embodiment, the coal undergoes a second micro-agglomeration step to enhance the efficiency of sulfur removal.
Another significant patent is the "Method for providing improved solid fuels from agglomerated subbituminous coal." This method focuses on separating agglomerated subbituminous coal from the heavy bridging liquid used in the agglomeration process. The separation is achieved by contacting the agglomerates with inert gas or steam at temperatures ranging from 250°C to 350°C, all while maintaining atmospheric pressure.
