CO2 Capture and Storage in Coal Gasification Projects

Studies on Co2 Gasification Reactivity of High Ash Indian Coal

Coal is a prime energy source in India and will continue to play its role for coming several decades. However, our indigenous coal suffers from high ash content and present coal based conventional power generation technologies have several drawbacks such as, lower efficiency, environmental loading and damages thereof. Herein the importance of gasification lies because coal gasification is a mea...

CO2 Gasification Reactivity of Chars Derived From Zhundong Coal

Coal gasification with carbon dioxide is a process for generating clean gaseous fuels and relieving greenhouse effect. Zhundong coal has high alkali and alkali earth metals (AAEMs) content, medium volatile and low ash in nature. Isothermal CO2 gasification of char derived from Zhundong coal (R-char) and char from acid washing R-char (AR-char) are performed in thermo-gravimetric analyzer (TGA). ...

Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO2 and zero emission during hydrogen energy production causes high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is th...

Comparative Assessment of Gasification Based Coal Power Plants with Various CO2 Capture Technologies Producing Electricity and Hydrogen

Seven different types of gasification-based coal conversion processes for producing mainly electricity and in some cases hydrogen (H2), with and without carbon dioxide (CO2) capture, were compared on a consistent basis through simulation studies. The flowsheet for each process was developed in a chemical process simulation tool "Aspen Plus". The pressure swing adsorption (PSA), physical absorpt...
