Selective hydrogenation of 1,3-butadiene: Improvement of selectivity by using additives
(Elsevier Science Sa, 2004-05)
The objective of this work is to evaluate the behavior of isoprene as an additive to improve selectivity in the selective hydrogenation of 1,3-butadiene from 1-butene-rich cuts. To this end, the liquid-phase hydrogenation ...
RECOVERY OF p-TBC FROM A BUTADIENE WASHING STREAM IN A PILOT PLANT
(BRAZILIAN SOC CHEMICAL ENG, 2009)
Results obtained in a pilot-scale unit designed for COD removal and p-TBC (p-tert-butylcatechol) recovery from a butadiene washing stream (pH 14, 200,000 mg COD L(-1), highly toxic) at a petrochemical industry are presented. ...
Recovery of p-TBC from a butadiene washing stream in a pilot plant
(Brazilian Society of Chemical Engineering, 2009)
Results obtained in a pilot-scale unit designed for COD removal and p-TBC (p-tert-butylcatechol) recovery from a butadiene washing stream (pH 14, 200,000 mg COD L-1, highly toxic) at a petrochemical industry are presented. ...
Kinetic evaluation of the set of reactions in the selective hydrogenation of 1-butyne and 1,3-butadiene in presence of n-butenes
(American Chemical Society, 2013-05-25)
The selective hydrogenation in the liquid phase of 1-butyne and 1,3-butadiene in the presence of n-butenes over a commercial Pd/Al 2O3 egg-shell catalyst has been studied. Although hydrogenation of the n-butenes and their ...
Experimental procedure for kinetic studies on egg-shell catalystsThe case of liquid-phase hydrogenation of 1,3-butadiene and n-butenes on commercial Pd catalysts
(Elsevier Science, 2001-01-20)
A study of the liquid-phase hydrogenation of 1,3-butadiene on commercial Pd/Al2O3 catalysts of the “egg-shell” type has been performed. Experimental conditions (40◦C, 4 atm and high conversion of the di-olefin) were selected ...
