PHEIDIAS aims to bring into the market an innovative hydrometallurgical process for the recovery of Platinum Group Metals (PGMs) from Spent Vehicle Catalytic Converters (SVCCs). This technology offers an increased material recovery rate and significantly lower operational costs, as the recovery rates of PGMs from SVCCs, namely Platinum (Pt), Palladium (Pd), and Rhodium (Rd), have already reached ~98%, ~98% and ~60% respectively. This novel process requires significantly less energy loads than the pyro-metallurgical processes mostly employed in the ESEE region. Furthermore, waste management performance is improved, as this innovatory technology uses solvents in lower concentrations.
The project will focus on the markets of Greece, Poland, Hungary,
Bulgaria, Slovakia, Slovenia, Romania, Cyprus, and Serbia, where project
partners have already developed a network of SVCCs suppliers through their
previous collaboration in the INNOCAT and
INNOCAT-up projects. To that end,
partners will upscale and pilot-test the proposed technology at large-scale
operation conditions, bringing it from Technology Readiness Level (TRL) 5 to
TRL 8 during the project, commercialising it within one year after project
completion (TRL 9), in 2023.
Upscale an innovative hydrometallurgical process from TRL5 to TRL8 for the recovery of PGMs from SVCCs in ESEE (East and South East Europe) participating countries.
Create a secondary source of PGMs value-chains, with an ever increasing potential, that will contribute in the long term to the partial replacement of the primary sources of these metals.
environmental and economic benefits, through the increase of the recovery rates
of Platinum (Pt), Palladium (Pd) and Rhodium (Rh) and reduce liquid waste, as
compared to processes currently employed in the ESEE participating countries
Help towards the alignment of the first and third strategic objectives of EIT Raw Materials, i.e. the securing of raw materials supply and the closing of materials loops respectively.
of the low acidity single step leaching/recovering batch hydrometallurgical
method lies in the following:
The above have already resulted in a 4-fold reduction in solvent use and a 7-fold increase in the solid to liquid ratio. A batch that is the solubilisation reactor (main unit of PHEIDIAS process) will hold 1000kg of deactivated monoliths (approximately 1400 SVCCs). The volume will be about 1.5m³ (Monolith process uses 70% solid to liquid ratio). A second reactor of approximately the same capacity is required to recover the PGMs. Finally, a small electrochemical reactor (about 5Kg) is required for PGMs refining.
