Syngas Chemical Looping Process for Hydrogen Production: Bench Scale Demonstration and Process Simulation
The Syngas Chemical Looping (SCL) process converts gaseous fuels such as syngas and hydrocarbons into hydrogen and electricity while capturing 100% of the CO2 generated 1, . The SCL process simplifies the overall fuel conversion scheme while reducing pollutants in an indirect but highly effective manner. This is achieved via a specially tailored Fe2O3 based composite particle. As a result, hydr...
متن کاملParticle Size Optimization for Syngas Chemical Looping Process
The syngas chemical looping (SCL) process developed at the Ohio State University can efficiently convert coal derived syngas into hydrogen with in-situ CO2 capture. In this novel process, two moving bed units are used to convert syngas into hydrogen through the assistance of an oxygen carrier particle. A third unit, an entrained bed combustor, is used to convey the oxygen carrier particles to c...
متن کاملStoring syngas lowers the carbon price for profitable coal gasification.
Integrated gasification combined cycle (IGCC) electric power generation systems with carbon capture and sequestration have desirable environmental qualities but are not profitable when the carbon dioxide price is less than approximately $50 per metric ton. We examine whether an IGCC facility that operates its gasifier continuously butstores the syngas and produces electricity only when daily pr...
متن کاملChemical Looping Reforming – an Efficient Process for the Production of Hydrogen from Coal
A novel Chemical Looping Reforming (CLR) process is proposed in which a highly recyclable iron oxide composite particle is reduced with coal and then oxidized back with steam to generate hydrogen. The reduction of iron oxide with coal results in a mixture of CO2 and H2O in the exhaust stream which after water condensation provides a ready to sequester relatively pure CO2 stream. This eliminates...
متن کاملComputational Fluid Dynamics Study of a Complete Coal Direct Chemical Looping Sub-Pilot Unit
The present Computational Fluid Dynamics (CFD) work deals with the modeling of complete coal direct chemical looping sub-pilot unit which use coal as fuel and ferric oxide supported on alumina as an oxygen carrier. The 2D CFD model of the complete arrangement incorporating both fuel and air reactors and their inter-connecting parts was solved using FLUENT. The CFD model wa...
