文摘
Methanol and methylamines, especially trimethylamine, can be degraded over alloy surfaces togenerate byproducts and carbon deposits. The activity of various metal alloys for the degradationof methanol and methylamines to carbon has been investigated. Inconel 600, a high-Ni alloy,was found to be the most active for these degradation reactions, the cold-worked turnings yieldingcarbon from methanol/ammonia at 380 
C and from trimethylamine/ammonia at 430 C. All ofthe other alloys tested were resistant to bulk carbon deposition from methanol/ammonia, butsome of them caused bulk carbon deposition from TMA/ammonia at temperatures in the range450-490 C.
