Air gasification of wood chips, wood pellets and grass pellets in a bubbling fluidized bed reactor

, 2021
Gasification is an attractive method for biomass-to-energy conversion and fluidized bed design is one of the best options for large scale operation. A bubbling fluidized bed reactor was used to analyze the effects of biomass type, equivalence ratio (ER ...

Process study and CO2 emission reduction analysis of coal liquefaction residue fluidized bed pyrolysis

Frontiers in Energy Research, 2022
The direct coal liquefaction process usually produces a liquefaction residue of about 30% of its coal feed. The effective utilization of the coal liquefaction residue (CLR), which contains about 80% organic matter, is of great significance for improving ...

Model-Based Quality, Exergy, and Economic Analysis of Fluidized Bed Membrane Reactors

Membranes, 2021
In petroleum refineries, naphtha reforming units produce reformate streams and as a by-product, hydrogen (H2). Naphtha reforming units traditionally deployed are designed as packed bed reactors (PBR). However, they are restrained by a high-pressure drop,

Synthesis of highly dispersed Pt nanoparticles into carbon supports by fluidized bed reactor atomic layer deposition to boost PEMFC performance

NPG Asia Materials, 2020
The performance of proton exchange membrane fuel cells (PEMFCs) depends on the controlled size, dispersion and density of Pt nanoparticles (NPs) on carbon supports, which are strongly affected by the carbon characteristics and fabrication methods.

Computational fluid dynamic model of nonisothermal circulating fluidized bed riser for CO2 capture

Energy Reports, 2020
The concern about the environment is the driving force to reduce the CO2emission. The main source of CO2 emission is from the flue gas from combustion process. The K2CO3solid sorbent in circulating fluidized bed reactor (CFB) is nominated as an efficient
