  • Process and plant for producing hydrocarbons
    Patent number: 8426665
    Abstract: When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.
    Type: Grant
    Filed: November 25, 2008
    Date of Patent: April 23, 2013
    Assignee: Lurgi GmbH
    Inventors: Norbert Palauschek, Peter Trabold, Helmut Heurich, Manfred Hoffmann

  • Method for high-temperature short-time distillation of residual oil
    Patent number: 7507330
    Abstract: The invention relates to a method for a high temperature short-time distillation of residual oil. The method according to the invention is characterized by a technically simple recovery of a small residual fraction from a gas and/or oil vapour mixture produced by a mixing apparatus (1). Said small residual fraction contains large quantities of undesirable polluting catalytic substances (CCR, Ni, V, asphaltenes). For this purpose, the gas and/or oil vapour mixture produced by the mixing apparatus (1) is diluted with gas or water vapour in a column (17) at a temperature of 450° C. in such a way that a high boiling fraction, which has a high content of the pollutant substances and whose initial boiling point is higher than 450° C., is condensed and extracted.
