Catalytic Performance of Micro-Mesoporous Zirconosilicates Prepared by Non-Hydrolytic Sol-Gel in Ethanol-To-Butadiene Transformation and Related Reactions

Abstract: Synthesis of 1,3-butadiene (BD) from ethanol has experienced a true renaissance in recent years due to ecological and economic reasons. The open porosity and number of Lewis acid sites in metal silicates (M = Zr, Ta) have been reported in numerous studies as key factors enabling reaching high BD productivity. However, some microporous zeolites recently displayed very high BD productivity. To gain a deeper insight, we have applied non-hydrolytic sol-gel (NHSG) – a method well-known to produce highly porous and … Show more

“…Very similar results were previously obtained via the non-hydrolytic sol-gel (NHSG) process. 14,62 NHSG catalysts displayed higher acidity leading to higher production of ethylene. An important take away message is that AASG represents a reliable method to obtain highly dispersed Ta species in silica matrices.…”

“…Acetaldehyde might be used as a butadiene precursor in the so-called Lebedev process. [12][13][14][15] New sustainable catalytic pathways need to be developed to produce acetaldehyde and to overcome crude oil resources depletion.…”

“…Very similar results were previously obtained via the non-hydrolytic sol-gel (NHSG) process. 14,51 NHSG catalysts featured high Ta dispersion and displayed higher acidity leading to high ethylene production. An important take away message is that AASG represents a reliable method to obtain highly dispersed Ta species in silica matrices (even if the resulting acidity would need to be tempered in the context of the ETB reaction).…”
