“…There are three basic types of gasifiers, namely moving bed gasifier (MBG), fluidised bed gasifier (FBG), and entrained flow gasifier (EFG). These gasifiers differ in terms of handling feed [10,13,14], fluidised bed gasifiers [15][16][17][18], entrained flow gasifiers [10,[19][20][21]. (3)…”

“…The Moving bed gasifiers are again classified into two types depending on the direction of feed and gasifying agents flowing through them. A vast source of literature deals with different types of gasifiers, some of the studies are referred with respect to each type of gasifier: fixed or moving bed gasifiers 10, 13, 14, fluidised bed gasifiers 15–18, entrained flow gasifiers 10, 19–21.…”

The Physico‐chemical characteristics are inherent properties of fuel and their behaviour changes in different gasification conditions. The critical properties of the coal impede the gasifier's performance, and hence, a proper study is needed to develop and further enhance the gasification systems. A proper assessment of factors influencing gasifier performance and their optimization enables to select, alter, and adjust the conditions. The present paper reviews the effect of important coal properties and gasifier operating conditions on gasification performance parameters. Further, the suitability of gasifiers (moving bed, fluidized bed, and entrained flow) according to the physico‐chemical properties of fuel along with proper operating parameters has also been studied.

“…There are four main CO 2 capture technologies, that is, chemical absorption, adsorption, membrane separation and cryogenic distillation. Chemical absorption is the most researched, implemented and commercialized option among the named separation technologies, especially in post‐combustion capture due to its distinct advantages 11,14,29–35 . These advantages include excellent CO 2 absorption efficiency of 80–100%, adaptability to low‐pressure conditions and capability to produce high purity CO 2 (up to 99%) 2,12–14,31,32,34,36–41 .…”

Review of carbon capture absorbents for CO₂utilization

2022

View full text Add to dashboard Cite

Carbon capture technologies have been recognized as a potential alternative to alleviate global warming. Carbon capture and storage (CCS) is preferred over carbon conversion and utilization (CCU) due to its lower operating costs and higher CO2 reduction capability. Nevertheless, CO2 utilization has the potential to be more economical if value‐added products are produced. This highlights the importance of assessing CO2 utilization routes and alternatives in carbon management. This review paper aims to evaluate the carbon utilization potential of major CO2‐capturing absorbents including amine, hydroxide, ionic liquid, amino acids and carbonate absorbents. All absorbents show potential application for CO2 utilization except for ionic liquids (ILs) due to their unclear CO2 capture mechanisms. Absorbents that require a desorption process for CO2 utilization include MEA, MDEA, K2CO3 and Na2CO3 due to their high absorption capacity. Industries have utilized the desorbed CO2 as chemical feedstocks, enhanced oil recovery (EOR) and mineral carbonation. For hydroxide absorbents and CaCO3, desorption of CO2 is unnecessary as the absorbed CO2 can be directly utilized to produce construction materials. Apart from that, the incorporation of advanced technologies and business models introduced by the fourth industrial revolution are plausible considerations to accelerate the development of carbon capture technologies. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.

Parametrization of a Sectional Approach for the Entrained-Flow Gasification of Biomass Char

2021

The thermochemical conversion of biomass, through gasification and consecutive fuel synthesis, can produce high-quality fuels. Entrained-flow gasification is regarded as the forthcoming technology providing syngas of sufficient quality, though the technology readiness level needs to be raised to allow its wide use. To this end, investigations within the bioliq project have been conducted on the gasification of fast pyrolysis products: pyrolysis oil and biochar, forming together a so-called bioslurry. This article will present the parametrization and results of numerical simulations of entrained-flow gasification. A first set of simulations on the gasification of a liquid fuel on two well-referenced experimental data sets is presented. Here, the liquid is monoethylene glycol, a surrogate for pyrolysis oil. Then, simulations of slurry fuels are considered, where the conversion of the biochar particles is numerically solved with a sectional approach. The simulations prove to retrieve the experimental results with a high accuracy, thus making CFD simulations based on the proposed approaches an adapted tool to investigate further operating conditions or for scaling-up. Particular attention is drawn on the parametrization of the approach. It will be shown that the majority of the model’s parameters, such as the pseudospecies size distribution, composition, and thermodynamic properties, can be derived from regular analytical chemistry techniques. The parameter with the highest sensitivity was identified to be the gasification reaction rate of the secondary char. The proposed model is sensitive to the properties of different types of biochar as well as to the amount of solid in the slurry fuel. By presenting a methodology, which can be quickly adapted to further solid fuels, the present work will allow for tackling the variability of biomass-derived fuels and find suitable operating conditions adapted to specific biomass conditions.
