Hyperzone PE Process Technology Dr. Gerben Meier Associate Director, Hyperzone Technology Development and Commercialization February 26, 2019 Company confidential

Our company has developed new products and technologies that are the bedrock of the chemical industry

Hyperzone PE technology extends our differentiation New Hyperzone PE investment for high density polyethylene (HDPE) offers resins with: Combination of LyondellBasell PE and PP technical expertise Light weighting by optimizing stiffness, stress crack resistance and strength Enhancing sustainability by using less material for same functionality One catalyst chemistry covering full range of HDPE Synthesis of 1st HDPE at low pressure 1st bimodal Hostalen Launch of benchmark PE 100 pipe grade 1st Hostalen ACP 1st Hyperzone PE plant

HDPE markets have evolved due to capabilities of different catalyst technologies Narrower processing window compared to Cr grades (Film, SBM) Superior mechanical properties compared to Cr grades Single/multimodal reactor setup Excellent ESCR/impact balance Very good processability Multimodality is key – cascade setup Excellent processability Poor mechanical properties (film) ESCR/impact balance inferior to ZN grades (SBM) Single reactor setup Excellent processability Excellent surface quality Medium ESCR/impact balance Single reactor setup Based on our ZN catalyst technology the Hyperzone PE process will be able to serve all markets Company confidential

LyondellBasell Process Knowledge LyondellBasell Catalyst Knowledge Hyperzone PE is based on 70 Years of LyondellBasell knowledge LyondellBasell Process Knowledge Hostalen ACP Multimodal reactors Spherilene FBR reactor operation Spherizone PP MZCR design and operation Hyperzone PE LyondellBasell Catalyst Knowledge Hyperzone PE is the first process able to serve ALL HDPE markets based on using our innovative spherical ZN catalyst technology. Fluid Bed Reactor (FBR) Multi-zone Circulating Reactor (MCR)

Hyperzone PE gas phase reactor cascade for the production of multimodal HDPE Unique 3 in 2 cascade reactor setup; superior ZN product properties that can design grades with differential properties while maintaining excellent processability 2nd Reactor Multizone Circulation (MZCR) Company confidential

The function of the multizone circulating reactor makes the difference One circulation cycle = about 2 minutes; residence time 2 hours = average 60 cycles per polymer sphere; very homogeneous high molecular weight copolymer 2nd Reactor Multizone Circulation (MZCR) Company confidential

The Multi Zone Circulating Reactor (MZCR) Makes the Difference – Principle of the Barrier Condensate (>90 % propane) Dp vsolid Bimodality in molecular weight between riser and downer can be influenced by the barrier (Combination of Dp, vsolid and amount of barrier liquid) High barrier efficiency  low H2 in downer  strong bimodality in the MZCR

Spherical ZN catalyst and innovative process deliver exceptional product homogeneity Company confidential
