Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Characterization of Fly Ash for Their Effective Management [PDF]
, 2015 Coal based thermal power plants more or less producing 150 tons of fly ash each year. Endeavours to utilize fly ash powder have come to just a twenty to thirty percent reutilization rate. Around 80 percent of the power generation is from coal based power

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Agglomeration of bed materials during circulating fluidised bed (CFB) combustion or gasification of high‐alkali fuel is a practical challenge in industrial practice. This work investigates experimentally the effect of temperatures (700°C–900°C) and atmosphere (air equivalence ratios 1.61–0.53) on agglomeration in a lab‐scale bubbling fluidised

Penggunaan Abu Terbang Batubara Pada Pembuatan Batako Di Kota Palu [PDF]
, 2012 One cause of the poor quality of some concrete blocks in the city of Palu is the lack of cement used in the concrete block. This is caused by the high price of cement so that income of concrete blocks maker decreases. To find a way out of these problems,

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Biomass energy plays a critical role in alleviating environmental pressures. However, its relatively high content of alkali metals (especially for potassium) would cause ash‐related issues during combustion. To mitigate these issues, the potassium migration behaviors during chestnut shell (CS) conversion and the modification mechanisms of ...
