Publication number: 20140079613Abstract: An absorption medium for removing acid gases from a fluid stream comprises an aqueous solution of A) at least one cyclic amine compound having solely tertiary amine groups and/or sterically hindered secondary amine groups and B) at least one cyclic amine compound having at least one sterically unhindered secondary amine group. The absorption medium comprises, e.g., an aqueous solution of A) 1-hydroxyethylpiperidine and/or triethylenediamine and B) piperazine. The absorption medium is particularly suitable for separating off carbon dioxide from flue gases and satisfies the following criteria: (i) sufficient capacity at low CO2 partial pressures; (ii) sufficiently rapid absorption rate at low CO2 partial pressures; (iii) stability toward oxygen; (iv) low vapor pressure for reducing solvent losses; and (v) low energy requirement for regeneration of the absorption medium.Type: ApplicationFiled: November 19, 2013Publication date: March 20, 2014Applicant: BASF SEInventors: Hugo Rafael Garcia Andarcia, Ute Lichtfers, Georg Sieder, Oliver Spuhl, Steven Brughmans

Patent number: 8466322Abstract: Process for preparing tri-n-propylamine (TPA), wherein di-n-propylamine (DPA) is reacted in the presence of hydrogen and a copper-comprising heterogeneous catalyst. An integrated process for preparing TPA, which comprises the following operations: I) reaction of n-propanol with ammonia in a reactor in the presence of an amination catalyst and optionally hydrogen to form a mixture of mono-n-propylamine, DPA and TPA, II) separation of unreacted ammonia, unreacted n-propanol and possibly hydrogen from the reaction product mixture and recirculation of at least the ammonia and propanol to the reactor in I) and also separation of the n-propylamine mixture by distillation and isolation of the TPA, III) reaction of the DPA obtained in the separation by distillation in II) in a reactor in the presence of hydrogen and a copper-comprising heterogeneous catalyst to form TPA and IV) feeding of the reactor output from III) to operation II).Type: GrantFiled: June 30, 2011Date of Patent: June 18, 2013Assignee: BASF SEInventors: Kevin Huyghe, Steven Brughmans, Falk Simon, Johann-Peter Melder, Peter Raatz

Process For Separating Off Acidic Gases By Means Of Metal-Organic Frameworks Impregnated With Amines
Publication number: 20120070353Abstract: The present invention relates to a process for separating off at least one acidic gas from a gas mixture comprising at least one acidic gas, which comprises the step of contacting of the gas mixture with a porous metal-organic framework, where the framework adsorbs the at least one acidic gas and the framework comprises at least one at least bidentate organic compound coordinated to at least one metal ion, wherein the porous metal-organic framework is impregnated with an amine suitable for a gas scrub. The invention further provides such impregnated metal-organic frameworks.Type: ApplicationFiled: March 18, 2010Publication date: March 22, 2012Applicant: BASF SEInventors: Natalia Trukhan, Ulrich Müller, Johann-Peter Melder, Steven Brughmans, Torsten Katz -
