Researchers have studied sulfide-type catalysts for the production of mixed alcohols from synthesis gas for several decades. Despite many advances in the art, these processes are not yet commercial, due in large part to mediocre economics and the added risk associated with uncertainty in catalyst lifetime. This talk will outline some recent studies in the lifetime and stability of K-CoMoSx-type mixed alcohol catalysts. Specifically, studies of long term operation (> 3000h), sulfiding agents, simulated methanol recycle, and morphology (probed via XRD and XPS) will be discussed, with the conclusion that these materials are likely to exhibit acceptable lifetimes in continuous operation.
