Abstract: Coal burning waste gases, notably carbon dioxide (CO2), can be removed or sequestered, and the distribution and utilization of coal as a safe, efficient, and convenient heat source can be improved. Carbon dioxide, a waste gas as from a coal burning process, can be sequestered within freshly fractured rock particles, such as Oligocene rock serpentine, using an adapted version of a rotary collider to fracture down hens-egg sized incoming rocks in a pressurized waste gas. The process sorts the small, fractured rocks and coats them after CO2 sequestration with a cementitious coating for use as a component of building material. In order to improve the transport and delivery of mined coal it is an advantage to fracture the coal and coat the particles with an aqueous liquid. The methods and apparatus deal with the improved delivery of said liquid-coated coal particles for current and new customers who become interested in using coal as an economical heating fuel.
