Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide catalyst deactivation and low conversion rate (around 50–60%) could limit the application of metallic catalysts in lignin depolymerization due to the cost of the processing and chlorine.. Titanium was discovered in Cornwall low density
