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 ...

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

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...

The Effect of Sintering Flue Gas Composition on NO Reduction in Coke
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The strategy of substituting combustion air with sintering flue gas in circulating fluidized bed (CFB) systems provides a low‐cost and highly efficient approach for the purification of sintering off‐gas. In this work, coke was employed as the reducing agent, and a high‐temperature vertical tube furnace was used to simulate the dense‐phase ...
