Exergy sustainability analysis of biomass gasification: a critical review

نویسندگان

چکیده

Biomass gasification technology is a promising process to produce stable gas with wide range of applications, from direct use the synthesis value-added biochemicals and biofuels. Due high capital/operating costs necessity for prudent management thermal energy exchanges in biomass process, it important advanced sustainability metrics ensure that environmental other factors are addressed beneficially. Consequently, various engineering techniques being used make decisions on endogenous exogenous parameters processes find most efficient, viable, sustainable operations conditions. Among available approaches, exergy methods have attracted much attention due their scientific rigor accounting performance, cost, impact systems. Therefore, this review devoted critically reviewing numerically scrutinizing analyzing First, bibliometric analysis conducted systematically identify research themes trends exergy-based assessments Then, effects composition, reactor type, gasifying agent, operating efficiency thoroughly investigated mechanistically discussed. Unlike oxygen, nitrogen, ash contents biomass, positively correlated carbon hydrogen biomass. A mixed medium (CO2 steam) provides higher values. The downdraft fixed-bed gasifier exhibits highest among Finally, opportunities limitations aspects systems outlined guide future domain.

Energy and Exergy Analysis of High Temperature Agent Gasification of Biomass

A chemical equilibrium model was developed to predict the product composition of a biomass gasification system using highly preheated air and steam. The advantages and limitations of this system were discussed from a thermodynamic viewpoint. The first and second law analyses have been conducted for various preheating temperatures and steam/biomass mass (S/B) ratios. The results demonstrated tha...

Biomass Gasification

Modern agriculture is an extremely energy intensive process. However high agricultural productivities and subsequently the growth of green revolution has been made possible only by large amount of energy inputs, especially those from fossil fuels. With recent price rise and scarcity of these fuels there has been a trend towards use of alternative energy sources like solar, wind, geothermal etc....

Performance analysis of integrated biomass gasification fuel cell (BGFC) and biomass gasification combined cycle (BGCC) systems

Biomass gasification processes are more commonly integrated to gas turbine based combined heat and power (CHP) generation systems. However, efficiency can be greatly enhanced by the use of more advanced power generation technology such as solid oxide fuel cells (SOFC). The key objective of this work is to develop systematic site-wide process integration strategies, based on detailed process sim...
