High-Temperature Graphitization Failure of Primary Superheater Tube
High Temperature Materials and Processes, 2015 Failure of boiler tubes is the main cause of unit outages of the plant, which further affects the reliability, availability and safety of the unit. So failure analysis of boiler tubes is absolutely essential to predict the root cause of the failure and ...

Carbon‐negative hydrogen from ethanol via catalytic oxidative reforming
Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1442-1450, November/December 2025.Abstract This study evaluated a commercial technology for producing low‐ or negative‐carbon hydrogen through ethanol catalytic oxidative reforming, focusing on the life cycle greenhouse gas emissions, or carbon intensity (CI). Various scenarios were analyzed: (a) comparing corn ethanol (first‐generation or Gen1 ethanol) and cellulosic ethanol (second ...
