Chemist, University of Leiden, NL December 3, 20142

3 HyVent Technology Core Technology ⇨ HydroThermal treatment Testing facilities in The Netherlands and Germany December 3, Processes in the sub- or super- critical regime of water

4 HyVent Technology application areas Synthesis Oxides Ferrites Heavy Oil Upgrading Bitumen Vacuum Resid Removal of metals Spent refinery catalysts Mixed oxides Destruction Toxic wastes Organic/Inorganic mixtures High COD water December 3, 20144

5 Historical Molybdenum (Mo) pricing Historical Molybdenum (Mo) pricing Hydroprocessing Catalyst contain 15-25% MoO 3 MoO3 price (USD/lb) ? ? Year December 3, Historical pricing 2.5 $/lb

6 Spent hydrotreating catalysts are both a hassle and a source of value for refiners Co-Mo Ni-Mo 160,000 tpa Remove S from oil Legal waste disposal obligation Hazardous waste >20% metals Largely Mo 20 % Carbon and Sulfur Needs to be removed prior to processing Metals value  4000 $/ton Metals value  4000 $/ton Needs to be removed prior to processing Export Documentation and transport hassle Liability risk when done incorrectly December 3, 20146

7 High costs in metal recovery value chain limits return to refiner Unload spent catalyst Special packaging Roaster for C,S removal Metal reclaim > 65% generated in North America, Europe, Middle East > 65% reclaim capacity in Asia ⇨ Large transport volumes, Export chemical waste Large facilities Roasting and metal reclaim often not at same site ⇨ Multi-step location, international processing, documentation hassle Total costs > $ 2500 /ton December 3, 20147

8 Current metal recovery technologies for Mo and V have serious limitations Roasting for Carbon and Sulfur removal – Environmentally unfriendly – High capital investment, High maintenance Pyro metal recovery – Smelting of material in electronic furnaces – yielding Ferro-alloys used in steel industry, no re-use for catalysts – Low recovery value (alloy) – High capital investment, High energy consumption Hydrometallurgical metal recovery – Chemical leaching with acid or base materials – Complex processing with many contamination limitations – Environmentally unfriendly waste waters December 3, 20148

9 HyVent’s Integrated Processing Scheme Hydrothermal dissolution of C, S and metals Destruction of organic compounds Hydrothermal dissolution of C, S and metals Destruction of organic compounds Combination of proven processes from catalyst and battery recycle industry Zero Liquid Discharge process High recovery value for M and V Combination of proven processes from catalyst and battery recycle industry Zero Liquid Discharge process High recovery value for M and V Hydrothermal processing Metal Recovery Spent Catalysts Water energy CO 2, N 2 Metal salts solids Integrated Metal Recovery Process December 3, 20149

10 The HyVent process is environmentally friendly No waste water or NO X and SO X emission s feed grind mill mix HP Pump HT Reactor treatment + leaching HT Reactor treatment + leaching depressurize centrifuge Solids collection Mo recovery Water treatment Alumina/Ni/Co cake liquids Molybdenum salt Clean water for re-use Salts for disposal Pretreatment Reactor Separation Recovery Additives Water Spent Catalyst V- recovery Vanadium salt December 3, Solids Liquids

11 HyVent uses all commercially proven equipment All stackable, modular container framed & sized equipment Tubular Hydrothermal Reactor system Slurry of un- regenerated catalyst prior to hydrothermal treatment Slurry of un- regenerated catalyst prior to hydrothermal treatment December 3,

12 HyVent’s process has strong advantages Current Processes Large, fixed units High CAPEX Multi-location process: - Roasting separate from metal recovery - multi transport, non-local - export Metal recovery pyrometallugy ⇨ ferro-alloy (low value) hydrometallurgy ⇨ large acqueous waste volumes Gas emissions Sulfuroxides, CO2, NOx and C- compounds Current Processes Large, fixed units High CAPEX Multi-location process: - Roasting separate from metal recovery - multi transport, non-local - export Metal recovery pyrometallugy ⇨ ferro-alloy (low value) hydrometallurgy ⇨ large acqueous waste volumes Gas emissions Sulfuroxides, CO2, NOx and C- compounds HyVent Hydrothermal Process Modular, small Low CAPEX Local, single location process ⇨ C & S removal in process ⇨ Local single transport Mo and V compound as salt solutions ⇨ high value Zero Liquid Discharge ⇨ recycle process water HyVent Hydrothermal Process Modular, small Low CAPEX Local, single location process ⇨ C & S removal in process ⇨ Local single transport Mo and V compound as salt solutions ⇨ high value Zero Liquid Discharge ⇨ recycle process water December 3,

13 HyVent will build local, customized, modular facilities to eliminate transport hassle and reduce costs Modular, containerized local facility NO transport, NO documentation hassle High return value for Mo and V metal recovery Modular facility with ‘plug and play’ construction set up Low CAPEX ⇨ 5-6 million USD per plant ZLD processing, full water recycle, no emissions High flexibility to adapt to local market – Mo or Mo and V recovery – Chemical catalyst processing with other metals (Cu, Zn, RE etc.) add on possible – Noble metal recovery scheme under development December 3,

14 Several tpa facilities can be build around refining centers in the world Asia Americas Europe Global hydro-processing spent catalyst generation (tons/year) America’s, Europe, export >65 % of spent catalyst to Asia Pacific now (VN, K, CN, TW) America’s, Europe, export >65 % of spent catalyst to Asia Pacific now (VN, K, CN, TW) # # Potential number of facilities by region

15 Better return to refiner with HyVent: ⇨ avg >700 $/ton over past 15 years !! Net return difference for refinery HyVent vs competition (current pricing) Net return difference for refinery HyVent vs competition (current pricing) December 3, Year (+2000) USD / ton

16 Higher value return to Refinery without hassle Recovery of Mo reduces refinery exposure to metal price fluctuations Swap recovered Mo with fresh catalyst Mo Better value recovery for refinery No documentation and transport hassle for refinery No export waste liability risk Long term guaranteed off-take agreement December 3,

17 Closing remarks The HyVent integrated HydroThermal process for treatment of spent refinery catalyst and recovery of Molybdenum offers an environmentally friendly, economic and flexible processing technology in answer to changing market demand and requirements Thank you for your attention December 3,
