Abstract: The known hydrocyanic acid-methane-ammonia (BMA) process for the production of hydrogen cyanide can now be carried out with liquified gases namely through the presence of additional hydrogen at the beginning of the reaction. The atomic ratio of carbon to nitrogen and hydrogen is from 1:1:7.1 to 1:1.33:13. As additional hydrogen there is the portion of hydrogen present coming out of the reaction "hydrocarbon+NH3". Otherwise the reaction conditions are the same as in the known BMA process.

Abstract: Activated carbon is produced from lignite coke. It is characterized by the product of the molasses number times the iodine number divided by 1000 being 350 to 1000 and/or the product of the molasses number times the methylene blue number divided by 10 being 500 to 1200. It is produced by adding aqueous alkali or alkaline earth carbonate solution and/or aqueous alkali or alkaline earth hydroxide solution by means of lance during the steam activation of lignite coke in a rotating tube.
