Summary

Ethylene is one of the principal building blocks in the petrochemical industry, and world-wide production and consumption have been steadily increasing. Production of ethylene is accomplished primarily by the pyrolytic stripping of hydrogen from ethane or a higher molecular weight hydrocarbon. This cracking process, sometimes referred to as steam cracking, is currently accomplished in metallic tubes in high temperature furnaces with a conversion efficiency, for ethane of 60-65%. Operation at significantly higher temperature could increase the efficiency as much as 20%, but materials with better high temperature strength would be required. To help identify suitable materials, tests have been conducted to determine the behavior of selected ceramic materials in environments similar to those anticipated for a high-efficiency, advanced steam cracking system. The effects of exposure on weight change, mechanical strength, and microstructure have been determined in a series of 100 hour tests. In addition, 500 hour tests have been conducted to determine the effect of time on material behavior. From these tests, several strong candidates have been identified.
