CoalTrans India 2019: AsianCAA to Discuss India’s Utilization Policies

Delhi, India

The annual Coaltrans India event will take place this February 18-20, at the Taj Palace Hotel in New Delhi, India.  Coaltrans events are very well established in the region, with 18 years of proceedings with an annual attendance of approximately six hundred international industry professionals.

The coal industry in India has changed drastically in the past few years, which makes this conference key in bringing decision makers together to discuss changes and strategies. India has transformed from a net exporter to importer, changing the way business is done, and who controls the flow of resources. Demand for coal-fired power increases every year, making electricity increasingly expensive to consumers. The government is very supportive of import initiatives, however there is still considerable demand to be satisfied by outside sources. The largest contributors to India coal are Indonesia and the US (Click below to read about Indonesian coal trends from our last blog post). India entering the import business of coal will be a big topic at this year’s event.

Mr. David Harris, Chairman of the AsianCAA and industry leader with over 20 years experience in developing green technology, new materials and supply chain service companies will be in attendance alongside other members of the AsianCAA. The Association plans to be a meaningful contributor throughout Coaltrans proceedings.  Mr. Harris will lead a talk and presentation regarding the logistics of import/export as well as new and interesting technologies surrounding processing and handling. This will be AsianCAA’s 4th visit to a Coaltrans event.

Research Highlight: Synthesis of High Quality Zeolites from Coal Fly Ash

- Perth, Australia

Dr. Kevin Li (Gang Li), participated in CAA2017 on behalf of the Centre for Energy, School of Mechanical & Chemical Engineering at the University of Western Australia in Perth, Australia. Dr. Li, a returning speaker to Coal Ash Asia, focused his presentation on synthesizing zeolites and necessary related conditions. The below abstract is an overview of the research presented at the conference. For more of Dr. Li’s publications and research, please click the link at the bottom of the abstract.

Abstract: Coal fly ash is a hazardous industrial waste generated from coal combustion and has been considered as an appropriate raw material for zeolite synthesis. In this study, synthesis of a high-quality type A zeolites (471m /g surface area) from fly ash at high conversion rate (98.2% aluminium and 96.5% silicon) has been achieved via a two-step alkali fusion and hydrothermal procedure. Furthermore, in preparation for production in commercials scale, up scaling of the developed synthesis process has been undertaken by using 150L reactor. More importantly, we tracked the migration of elements and quantified their distribution from fly ash to product zeolites and waste water throughout the synthesis process. Metalloid elements including arsenic and selenium, and those with strong amphoteric properties such as molybdenum were found highly mobile and mostly collected in the waste water. In comparison, less than 20% of heavy metal elements of weak amphoteric nature including copper, chromium and lead originated from the fly ash went to the waste water; the rest of these three heavy metals along with almost all of the cadmium, iron and nickel were fixed into the product zeolites. Despite the accumulation of hazardous elements in product zeolites, none of them was leachable under various harsh conditions, ensuring safe applications of such zeolites.

China Coal Combustion Product Conference: Technological Innovation to Promote Green Development

- Shuozhou City, Shanxi Province, China

The Asian Coal Ash Association would like to thank all who participated in CICCPC 2017, the most recent international exchange in Shuozhou. This year’s topics focused on fly ash and desulfurized gypsum, with the theme "Technological Innovation to Promote Green Development". During the two day event participants engaged in technical exchanges on comprehensive utilization of fly ash and gypsum and discuss the latest scientific research.

One goal of the conference was to further strengthen international and domestic cooperation to promote technological progress and industrial development. Experts from the U.S.A, Germany, Australia, Canada, Ukraine and Japan were among the 700 participants at this year’s event.

The conference was jointly organized by AsianCAA, the National Institute of Building Materials Industry Information, Shuozhou Municipal People's Government, and the Shanxi Economic and Information Commission.  Mr. David Harris, the chairman of the Asian Coal Ash Association gave keynote and regular session speeches during the proceedings. Mr. Harris outlined coal ash and other solid waste utilization technologies, international trade status’ and industry development prospects.

In conjunction with the regular plenary session, was a product/technology exhibition and academic poster display. A variety of specialized meetings also took place at CICCPC. The meeting of the National Coal-based Solid Waste Resource Industry Technology Innovation Strategic Alliance took place for the first time during proceedings. There was a Fly Ash Intelligent Sales Control System meeting as well as a special Green Building Materials and Construction Technology exchange. The Ceramic Association business forum convened during the 23rd of September and  Shuozhou City Investment Promotion and Tourism Promotion gave a special inside look into regional operations. Guests were also able to enjoy an afternoon of horse racing at Youyo County and many other networking opportunities.

Discussing Free CaO in CFB Ash and it’s Stability: Research Highlight from Coal Ash Asia 2017


- Beijing, China

Professor Qiao Xiu Chen from East China University of Science and Technology joined the discussion at Coal Ash Asia this past July 21-24 in Beijing, China. Prof Chen presented among industry leaders during the Fly Ash and Coal Gangue Track at the most recent AsianCAA event. The below abstract has been translated from its original submission to our proceedings.

Abstract: Circulating fluidized bed (CFB) boilers discharge 2 to 3 times as much ash per 1 kWh as pulverized coal-fired boilers. Overall, the amount of discarded CFB ash has drastically increased in China. However, there is no bulk utilization due to the different physiochemical properties of coal fly ash (CFA) from pulverized coal-fired boilers. One of the key issues is the amount of CaO left after burning, as CaO has negative effects on the soundness of cement. The national standard requires the maximum free CaO of 1% for F CFA and 4% for C CFA. The amount of lime in CFB ash is usually higher than 5% due to the desulfurization process. The utilization of CFB ash becomes harder when ash contains higher amounts of CaO. Presentation Abstracts

This conference we will show the chemical reaction variations of lime prepared at 800, 850, 900, 950, 1000, 1050, 1150, 1250, 1350°C. The calorimetry, precise measurement of lattice parameter and selected area microdiffraction of TEM were used for evaluation. The results showed that the calcite with a fineness of D100<76μm decomposed by 80% after the treatment at 800 or 850°C for 20 min. Complete decomposition occurred from the treatment at 900°C for 10 min. The maximum amount of CaO was 0.53% after the treatment at 1050°C. The amount of CaO started to be higher than 1% from the treatment at 1150°C and was more than 30% after the treatment at 1350°C for 20 min.

The CFB ash does not show a negative effect on the soundness of cement when the highest combustion temperature in the boiler is lower than 1050°C.
