FOR IMMEDIATE RELEASE

St. Louis, MO — The Materials Technology Institute (MTI) has launched a new research initiative to better understand corrosion behavior in bio-oil processing environments, an area of increasing importance as energy producers and refiners explore lower-carbon alternatives to traditional crude oil.
“The outcomes of the MTI bio-oil corrosion research program will generate firsthand data in a previously underexplored service environment." according to Shahab Soltaninia, Project Co-Champion. These results will support bio-oil renewable energy producers, engineering service providers, alloy suppliers, and fabricators by enabling them to take a pioneering role in the sector and to develop fit for purpose solutions.”
Many MTI member companies are actively refining 100% crude bio-oils, co-processing renewable feedstocks, or designing facilities capable of operating with bio-oil streams. As interest in bio-derived fuels and feedstocks grows, understanding the corrosion behavior of these materials under real operating conditions has become a priority for engineers responsible for materials selection, inspection planning, and long-term equipment reliability.
The new study builds upon earlier MTI research conducted in Phase 1, which investigated high temperature fatty acid corrosion mechanisms associated with bio-oil processing. One of the key outcomes of those earlier research phases was the development of a flow-through corrosion testing method designed to simulate realistic operating conditions when evaluating metallic materials exposed to bio-oil environments.
MTI’s newly launched project will focus on fatty acid corrosion behavior at lower temperature operating conditions, particularly in equipment constructed from carbon steel and commonly used low-alloy materials. The objective of the new phase is to determine whether carbon steel and related alloys—including low-chrome steels and 300-series stainless steels—may exhibit acceptable corrosion rates under specific lower-temperature to moderate temperature bio-oil processing conditions. The research will again utilize the MTI flow-through testing methodology and will generate new experimental data to support materials selection decisions.
In addition to the new testing program, the project will include a comprehensive surface corrosion study of material coupons exposed during Phases 0, 1, and 2 of the research program. This analysis will provide a deeper understanding of corrosion morphology and degradation mechanisms observed across the testing phases.
The Phase 2 project will provide valuable insights for companies processing bio-oils in existing refining or processing units, particularly those relying on carbon steel and low-alloy metallurgy in preheat sections and related equipment. The findings may help facilities refine inspection programs, evaluate potential alloy upgrades, and better manage corrosion risks associated with bio-oil feedstocks, while also supporting more informed materials selection decisions for new bio-oil processing units.
As the energy industry explores lower-carbon fuels and renewable feedstocks, research like MTI’s bio-oil corrosion program helps ensure that materials of construction can safely and reliably support these evolving technologies.
