28 August- 2 September, Portugal
The Portuguese Chemical Society (SPQ), with the support of the Portuguese Electrochemical Society (SPE), has the great pleasure of organizing the 8thEuChemS Chemistry Congress (ECC8), to be held in Lisbon, Portugal, from August 28 to September 1, 2022.
The 8 EuCheMS Chemistry Congress is being built under the unifying theme of Chemistry the Central Science, focusing on the central role of chemistry at the interfaces with biology, material and environmental sciences, both for the progress of humankind and for the solution of fundamental problems of modern societies. An exciting scientific program led by world class experts will develop around seven main scientific topics:
- Advances in Synthetic Organic Methodologies
- Metal Containing Compounds and Solids: Properties and Applications
- Chemistry meets Biology
- Colloids and Materials
- Biomaterials and Medicinal Chemistry
- Spectroscopic and Analytical Tools / Advanced Physical Chemistry
Accompanied by three sessions devoted to topics of particular relevance to join scientists from different areas:
- Chemistry and Society
- Functional Materials
- Food Chemistry
And the final one organized by EYCN, the EuChemS European Young Chemists´ Network of EuChemS The program will be completed by three general and particularly important themes, which will run every day and provide a general view of the field, going beyond the view from each classical area:
- Molecules in Motion
- Energy, Environment and Sustainability
This conference will be the 8th in a series that started in Hungary, and was held in several cities before reaching Lisbon. All of them reached very high scientific levels, giving to all the participants the opportunity of listening to the most celebrated world speakers presenting state of the art advances in chemical sciences and to discuss openly with the chemistry community.
BlackCycle consortium with CERTH propose an abstract at the EuChemS200 Chemistry congress

Globally, an estimated one billion tyres reach the end of their useful lives every year . End-of-Life Tyres (ELT) are used today into a variety of recycling, public works and civil engineering applications, or are used as a fuel substitute in cement kilns, boilers and power plants. However, current ELT treatment processes are not circular and do not result in many raw materials that can be reused in the tyre industry. Furthermore, as there are not enough solutions to valorize materials from ELT in the EU, more than half of ELT are exported to far-off destinations. The recycling of materials in semi-closed loops is more circular and sustainable than burning materials for energy, especially when end-of-life products can be reconverted into equally high-added value new products. The EU-funded Horizon2020 BlackCycle project aims at creating, developing, and optimizing a full value chain from ELT to Secondary Raw Materials (SRMs) which can be used for the production of new tyres, with no waste of resources in any part of the chain and a specific attention for the environmental impact. This value chain consists of the ELT collection, pyrolysis and refining of the crude pyrolytic oil into added value fractions, and conversion of these fractions to SRMs for the manufacture of new tyres. In particular, the heavy fraction of the pyrolytic oil will be used as feedstock for the production of carbon black, a major tyre component (~20%) that is used as filler. However, upgrading of the pyrolytic oil is necessary to reduce its sulphur content and increase its aromatics content and C/H ratio, in order for it to become a suitable feed for the production of carbon black. The aim of this study is the hydrodesulphurisation (HDS) and the aromatisation of the heavy oil fraction of an ELT pyrolytic oil. The HDS of the heavy oil fraction was performed in a high-pressure fixed bed unit, with different commercial NiMo- and CoMo-based catalysts, at different reaction temperatures (325-375 °C), liquid hour space velocities (0.6-2 h-1 ) and at a pressure of 60 bar. Overall, a maximum sulphur reduction of 84% was achieved with a commercial NiMo catalyst. The aromatization process of the heavy oil fraction was studied over zeolites with different properties (silica-to-alumina ratio, surface area, acidity, etc.), such as USY, HZSM-5, HZSM-5 diluted and HY, under different experimental conditions. The results (C/H ratio versus liquid yields) of the zeolite screening in a micro-activity test unit at 400 °C and catalyst-to-oil ratio 1, 2, 3) are presented in Figure 1. The screening revealed that among the zeolites, HZSM-5 increased the C/H ratio up to 0.85 (from 0.76 for the heavy oil fraction). Further investigation of the aromatization process will take place with the investigation of the effect of metal(s) impregnation (such as Zn and Ga) and varying metal(s) loading over the zeolites.
