Keynote Topic: Progress in Biomass Torrefaction for Sustainable Solid Fuel Production


Development of renewable energy is considered as an effective countermeasure to abate anthropogenic CO2 emissions and mitigate global warming. Bioenergy accounts for the largest share among developing reviewable energies, and has been extensively applied in heat and power generation as well as residential and transport sectors. Biomass can also be directly utilized as a solid fuel and burned for heat and power generation. However, biomass possesses a number of disadvantages such as hygroscopic and biodegradable nature, high moisture content, low calorific value, poor grindability, large volume or low bulk density, and low homogeneity. These drawbacks give rise to a low conversion efficiency as well as difficulty in the collection, grinding, storage and transportation of biomass, thereby limiting the application of biomass in industry Torrefaction is a promising technology to upgrade biomass for sustainable solid fuel production. The aforementioned properties of biomass can be improved to a great extent after it undergoes torrefaction, making biochar approaches coal. As a consequence, torrefied biomass can be used as an alternative to coal consumed in industry. This talk addresses the progress in biomass torrefaction technology for biochar production, especially in the impact of this thermal pretreatment on the property variation of biomass. The applications of biochar in industry such as combustion, gasification, ironmaking, pyrolysis, and liquefaction are also underlined.

Keynote Topic: Carbon capture and storage: Technologies development and current status


Global warming and climate change concerns have triggered global efforts to reduce the concentration of atmospheric carbon dioxide (CO2). Carbon capture and storage (CCS) is considered a crucial strategy for meeting CO2 emission reduction targets. In this talk, various aspects of CCS are reviewed and discussed including the state of the art technologies for CO2 capture, separation, transport, storage, leakage, monitoring, and life cycle analysis. The selection of specific CO2 capture technology heavily depends on the type of CO2 generating plant and fuel used. Among those CO2 separation processes, absorption is the most mature and commonly adopted due to its higher efficiency and lower cost. Pipeline is considered to be the most viable solution for large volume of CO2 transport. Among those geological formations for CO2 storage, enhanced oil recovery is mature and has been practiced for many years but its economic viability for   anthropogenic sources needs to be demonstrated.  There are growing interests in CO2 storage in saline aquifers due to their enormous potential storage capacity and several projects are in the pipeline for demonstration of its viability. There are multiple hurdles to CCS deployment including the absence of a clear business case for CCS investment and the absence of robust economic incentives to support the additional high capital and operating costs of the whole CCS process. Lastly, the challenges and prospects of various carbon mediation measures, and their current status will be discussed.

Keynote Topic: Towards Green Refrigerants & Beyond Refrigerants


The first generation of refrigerants was all about accepting anything that works: heralding the era of Natural refrigerants. The second generation addressed concerns on safety (flammability), toxicity & durability: and saw the emergence of the Synthetic era. The third generation refrigerants sought to protect our ozone layer, resulting in the demise of CFCs followed by HCFCs. Today's fourth generation seeks to arrest global warming: and inevitably completing the circle back to the first generation refrigerants.

So what's next after the latest emerging HFOs and Naturals aka Green Refrigerants? Are we ready and prepared to move past the era of Synthetics and Naturals to a future of Non Rs?
