Slagging coal combustor for cementitious slag production, metal oxide reduction, shale gas and oil recovery, enviromental remediation, emission control and CO₂ sequestration

摘要

Systems, methods and processes teach by specific examples how the cost of sequestering carbon dioxide (CO₂) can be totally offset and turned into profits during coal powered electricity generation from revenue and co-benefits. The process is provided whereby fly ash-carbon mixtures, or de-volatilized coal char, or anthracite coal culm is co-fired in an air-cooled, slagging combustor with limestone or similar slag fluxing materials converts the ash into cementitious slag with properties similar to ground granulated blast furnace slag.
