Acrylic acid (AA) is a key commodity chemical in the petrochemical industry and is currently produced by the oxidation of propylene produced by naphtha catalytic cracking. However, its growing global demand and recent global climate change motivate us to develop a sustainable route for the production of AA. Lactic acid (LA), which can be produced easily by the fermentation of biomass sugars, is a good alternative to petroleum-derived propylene for the production of AA, and its dehydration to AA over solid acid catalysts has received much attention in the recent years. During the dehydration of LA, the undesired decarboxylation and decarbonylation also occur preferably, forming acetaldehyde. Thus, selectivity control for AA production in solid acid catalysts are highly challenging. This study aims to explore mechanism of the LA dehydration over alkali-exchanged Y zeolites by using an in-situ FT-IR spectroscopy which help us to rationally design the improved LA dehydration catalyst. |
