Haldor Topsøe is a Danish catalysis company, and was founded in 1940 by Dr. Haldor Topsøe. The company has over 2700 employees all over the world, of which 2100 work in Denmark.Haldor Topsøe specialises in the production of heterogeneous catalysts and the design of process plants based on catalytic processes. Focus areas include the fertiliser industry, chemical and petrochemical industries, and the energy sector . Haldor Topsøe A/S is one of the world's leading companies within the field of heterogeneous catalysis, and appx. 50 percent of the fertiliser used on a worldwide scale is made with the help of technology from Haldor Topsøe.In 2012, Haldor Topsøe A/S had a revenue of DKK 5.2 billion and an operating income of DKK 593 million before taxes .The headquarters are located in Lyngby, a northern suburb of Copenhagen, Denmark, but the actual manufacturing of catalysts is carried out in Frederikssund, Denmark, and in Houston, Texas. The company has offices or subsidiaries in Bahrain, Canada, China, India, Japan, Malaysia, Russia, South America, South Africa, and the USA. Haldor Topsøe’s catalysts and technologies are used to clean oil and ensure more environmentally friendly fuels, for cleaning power industry flue gasses, for converting hydrocarbon feedstocks such as natural gas and LPG into ammonia, hydrogen and methanol, and for reducing emission from heavy duty vehicles. In chemical plants catalysts and processes optimise resources, ensuring highly efficient energy processes.The founder, Haldor Topsøe, died on May 20, 2013 after a short illness, four days before he would have reached the age of 100. He was the chairman of the company from its founding until his death. His son, Henrik Topsøe, is now Chairman of the Board and Executive Vice President while Bjerne S. Clausen is President and CEO.

Catalysed filter consisting of a filter body of bio-soluble fibres catalysed with a catalyst comprising oxides of vanadium and titanium, wherein the total concentration of alkali metals in the filter body is less than 3000 ppm by weight and/or the total concentration of earth alkali metals in the filter body is less than 20% by weight.

The invention relates to a process for starting up a gas-to-liquid process including the production of synthesis gas and a downstream GTL process. The synthesis gas is produced by the use of autothermal reforming (ATR) or catalytic partial oxidation (CPO) and during the starting period the effluent gas from the ATR or CPO is significantly changed to form an off-gas recycle which is fed to the ATR or CPO. When the downstream GTL process is running, the recycle to ATR or CPO is shifted to its off-gas.

Process for the preparation of dimethyl ether product by catalytic conversion of synthesis gas to dimethyl ether comprising the steps of contacting a stream of synthesis gas comprising carbon dioxide in a dimethyl ether synthesis step in one or more reactors and with one or more catalysts active in the formation of methanol and dehydration of methanol to dimethyl ether and forming a product mixture comprising dimethyl ether, carbon dioxide and unconverted synthesis gas; cooling and separating the product mixture into a first liquid phase comprising dimethyl ether and carbon dioxide being dissolved in the formed dimethyl ether, and into a first gaseous phase comprising unconverted synthesis gas containing carbon monoxide and carbon dioxide; passing the first liquid phase to a scrubbing zone and contacting the phase with a liquid sorbent being effective in absorption of carbon dioxide; and withdrawing a dimethyl ether product being depleted in carbon dioxide from the scrubbing zone.


A catalysed particulate filter coated with a wash coat on its dispersion side and its permeate side and within partition walls of the filter. The wash coat contains a first catalyst active in burning off soot, together with a second catalyst active in a selective catalytic reduction of nitrogen oxides.
