The present invention relates to a process for the production of butadiene by condensation of ethanol using a catalyst containing sillica-supported elements from group 3A and group 4B of the periodic table. The catalyst of the present invention has high activity and selectivity to butadiene in the synthesis reaction of said olefin from ethanol.

A process and catalyst are provided for the non-oxidative dehydrogenation of propane for the production of propylene as petrochemical building blocks. The process provides a direct single-step gas-phase dehydration of propane mixed with nitrogen in the presence and absence of steam/hydrogen over supported bimetallic alumina-silicates zeolites. The catalyst contains no precious metal entities and may contain one metal from group VIB in combination with another metal from group IIIA or IVA supported on FAU, MFI, KFI, BEA type alumina-silicates zeolites. The process provides a propane conversion of 18% to 52% with a propylene yield of 10% to 25%.

The present disclosure generally relates to processes for preparation of n-butanol, n-octanol and n-decanol from a reaction mixture comprising ethanoi and n-hexanol by Guerbet condensation. In some aspects, the present disclosure relates to improvements in n-octanol and n-decanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol. The present disclosure further generally relates to integrated processes for preparation of n-butanol in a n-butanol reactor from a reaction mixture comprising ethanol and hydrogen to produce a n-butanol product stream by Geurbet condensation comprising n-butanol and n-hexanol and for preparation of n-octanol in a n-octanol reactor from a reaction mixture comprising ethanol, n-hexanol and hydrogen to produce a n-octanol product stream by Geurbet condensation comprising n-butanol, n-hexanol and n-octanol. A predominant proportion of the n-hexanol contained in the n-butanol and n-octanol product streams is isolated and recycled to the n-octanol reaction mixture. In some aspects, the present disclosure relates to improvements in n-octanol and n-butanol yield and selectivity by the selection of process reaction conditions such as, but not limited to, mole ratio of n-hexanol to ethanol and recovery and recycle of n-hexanol.
