An effective approach to the nature of relationships
between catalyst composition, textural properties and
conversion are essential for the design of adequate HAS
catalysts. The following general aspects were found out:
Textural properties are improved with the presence of
ZnO and Cs, but the evidence of a direct relationship
between these properties and any increment on alcohols
selectivity is low.
The highest butane selectivity at one hour on-stream was
obtained at 300 °C over CuCoCrNa catalyst and at 350 °C
over CuCoCrZnLi. Therefore, the impact of alkali pro-
motion on alcohols synthesis is uneven. The probability of
side reactions is always open since the ASF analysis
indicates breaks on the linear pattern of alcohol chains
growth.
