Engineering design and numerical design for chemical looping …
2024年9月1日 · Chemical looping combustion (CLC) has emerged as a cost-effective technology for carbon capture at the combustion source. The reactor, being central to the implementation of CLC, primarily adheres to two technological pathways: the dual fluidized bed reactor and the packed bed reactor.
Dual-dense gas-solid circulating fluidized bed reactor
2023年4月1日 · Circulating fluidized bed reactors are widely employed to deal with the gas–solid reactions in the energy industry. They could be classified into two categories as per the combination of fluidization regimes. The traditional circulating fluidized …
Modeling of Sorption-Enhanced Steam Reforming in a Dual …
2006年5月11日 · This paper highlights the use of a dual fluidized bed reactor system for producing hydrogen by sorption-enhanced steam methane reforming. Hydrogen concentrations of >98% are predicted for temperatures of ∼600 °C and a superficial gas velocity of 0.1 m/s, using a simple two-phase bubbling bed model for the reformer.

Methanol production in an optimized dual-membrane fixed-bed reactor
The membrane fixed bed reactor benefits are higher methanol production rate, higher quality of outlet product and consequently lower cost in product purification stage. This configuration has enhanced the methanol yield by 10.02% compared with industrial reactor.
Designing a novel dual bed reactor to realize efficient ethanol ...
A novel dual bed reactor packed with a combination of a zeolite (H-modernite or H-ferrierite) catalyst and a CuZnAl catalyst was proposed to realize direct ethanol (EtOH) synthesis from dimethyl ether (DME) and syngas (CO + H 2).
ABSTRACT: Copper and zirconium oxide clusters were highly dispersed on mesocellular siliceous foam (MCF), a mesoporous silica support with ultra large, interconnected nanopores. These catalysts (denoted as Cu/MCF and Zr/MCF) were separately loaded into two fixed bed reactors as catalysts for the conversion of ethanol (EtOH) to 1,3-butadiene (BD).
Review on Reactor Configurations for Adsorption-Based CO
2021年3月5日 · The fixed bed is the simplest reactor configuration where a flue gas is passed through a fixed bed of sorbents pellets (mm size) or through specially designed structured packings. Structure packings are used to optimize the surface areas and void space to achieve a high adsorption rate and low pressure drop.
