The chemical industry is under scrutiny for its significant contribution to CO2 emissions through traditional distillation processes. Serena Agnolin, in her PhD research, explored membrane reactor technology as an alternative to distillation for hydrogen production. By utilizing palladium membranes on metal tubes, Agnolin aimed to enhance hydrogen selectivity and efficiency. Overcoming challenges of deposition, Agnolin successfully developed stable membranes by filling metal tube pores with ceramics, improving hydrogen separation in chemical reactions. Her membranes demonstrated effectiveness in methane steam reforming and ammonia cracking, showcasing potential for diverse applications. Agnolin's innovative approach to membrane technology offers a promising solution to reduce CO2 emissions and energy consumption in the chemical industry.
