Abstract
In order to evaluate metal materials for a methanol-mediated extraction process, an electrochemical corrosion tests and an immersion corrosion tests of carbon steel (SS400) and stainless steels (SUS304 and SUS316L) were performed using a phenol-containing methanol-water solution recovered from a methanol-mediated extraction of naphtha fraction of Tanito Harum coal liquid.
In Both tests, the corrosion rates were 0.1-0.5mm/y on SS400, and less than 0.01mm/y on both SUS304 and SUS316L. From those results, it could be concluded that SUS304 and SUS316L are available for the plant materials, except SS400.
