Patent number: 9566571Abstract: A hexaaluminate-containing catalyst for reforming hydrocarbons. The catalyst consists of a hexaaluminate-containing phase, which consists of cobalt and at least one further element from the group consisting of La, Ba, and Sr, and an oxidic secondary phase. To prepare the catalyst, an aluminum source is brought into contact with a cobalt-containing metal salt solution, dried, and calcined. The metal salt solution additionally contains the at least one further element. The reforming of methane and carbon dioxide is great economic interest since synthesis gas produced during this process can form a raw material for the preparation of basic chemicals. In addition, the use of carbon dioxide as a starting material is important in the chemical syntheses in order to bind carbon dioxide obtained as waste product in numerous processes by a chemical route and thereby avoid emission into the atmosphere.Type: GrantFiled: February 8, 2013Date of Patent: February 14, 2017Assignee: BASF SEInventors: Stephan Schunk, Andrian Milanov, Andreas Strasser, Guido Wasserschaff, Thomas Roussiere

Publication number: 20160311684Abstract: A method of reforming mixtures of hydrocarbons, preferably methane, and carbon dioxide, wherein the method comprises at least two stages. In a first stage, a reactant gas is contacted with a precious metal catalyst and converted to a first product gas (also referred to hereinafter as product gas 1). In a second stage, the first product gas obtained in the first stage is contacted with a non-precious metal catalyst and converted to a second product gas (also referred to hereinafter as product gas 2). The process can also include adding gases to the product gas 1 obtained in the first stage. The practice of the process can minimize the formation of coke on the catalyst in an efficient manner. The combination of a first stage with a precious metal catalyst and at least one second stage with non-precious metal catalyst allows considerable amounts of costly precious metals to be saved.Type: ApplicationFiled: December 15, 2014Publication date: October 27, 2016Inventors: Andrian MILANOV, Ekkehard SCHWAB, Heiko URTEL, Stephan SCHUNK, Guido WASSERSCHAFF

Publication number: 20160207031Abstract: The present invention relates to a process for producing a catalyst for the reforming of hydrocarbons, preferably methane, in the presence of CO2, water and/or hydrogen. The production of the catalyst is based on contacting of a hydrotalcite-comprising starting material with a fusible metal salt.
