Abstract: This paper presents the design, development, and operation of a reactor system for CO2 capture. Modifications were implemented to address differences in sorbent from 180 μm Geldart group B to 115 μm Geldart group A material; ...

Abstract: ecial issue contains selected papers presented at the 42nd International Clearwater Clean Energy Conference. The conference was held at the Sheraton Sand Keys Hotel, Clearwater, FL during June 11–15, 2017. The endorsing ...

Abstract: For chemical looping processes to become an economically viable technology, an inexpensive carrier that can endure repeated reduction and oxidation cycles needs to be identified or developed. Unfortunately, the reduction ...

Abstract: The National Energy Technology Laboratory (NETL) has explored chemical looping in its 50 kWth facility using a number of oxygen carriers. In this work, the results for methane conversion in the fuel reactor with a hematite ...

Abstract: A study was conducted to explore the applicability of recurrence and recurrence quantification analysis (RQA) to the detection of process failures in spouted bed reactor systems. Three different potential failure modes ...

Abstract: A study was conducted to explore the effects of static bed height, nozzle diameter, cone angle, and particle properties on the minimum spouting velocity in a 4 in × 1 in rectangular spouted bed. Tests were conducted with ...

Abstract: Fluidized beds are used in many industries where gas–solid reactions are present for their favorable characteristics of good solids mixing, high heat, and mass transfer rates, and large throughputs. In an attempt to increase ...

Abstract: Tests were performed in a 0.1-m diameter small circulating fluidized bed (SCFB) and 0.3 m diameter cold flow circulating fluidized bed (CFCFB) riser systems located at the National Energy Technology Laboratory (NETL) to ...
