Plasma-Catalysis of CO2 and CH4 to Produce High Value Chemicals

The goal of this work is to develop a new technology that can produce acetic acid in a single-step and do so at reduced temperature and ambient pressure. Current techniques to synthesize acetic acid require methanol and carbon dioxide, both of which are largely made from syngas produced from dry reforming of methane. However, high temperatures are needed to produce the syngas (of which a component is carbon monoxide) and high pressures are then needed to produce methanol in current systems. This contributes to the overall cost of acetic acid and complexity of the process. In this Phase I study, we will combine plasma and catalysts to produce acetic acid in a single-step process, avoiding the need for high temperatures and high pressures. ACT has established partnerships with Lehigh University and a global syngas manufacturer to support the proposed work. ACT will develop a temperature-controlled plasma- catalysis reactor, evaluate defined catalysts, and perform experiments for different inlet compositions, flow conditions, and plasma powers. In parallel, we will work with our academic partner regarding catalyst synthesis and performance and our commercial partner to tailor the technology to meet industry performance and cost metrics.A number of products and chemicals are made from acetic acid, which is an intermediary for making coatings, greases, polyester, and sealants used in electronics, automotive, textiles, and packaging. Purified terephthalic acid (PTA) is a one product made from acetic acid and used to make polyethylene terephthalate (PET) bottles that we are all familiar with in our consumer goods. There are also medical applications and other applications for consumer products.
