摘要： As a result of a special form of the surface coating of Al.sub.2 O.sub.3 catalysts using additional amounts of aluminum ions and very slight amounts of platinum ions, Al.sub.2 O.sub.3 was able to be used as catalyst for continuous operation (150 days and longer) in the preparation of hydrogen cyanide from hydrocarbons and ammonia, preferably in the BMA method.

摘要： The previously carried out internal coating of contact tubes not only required very much manual labor and was very time consuming, but it was also unsatisfactory in regard to adhesion of the contact liquid to the surface and homogenity of the catalyst. By the simultaneous action of heat on the liquid interface in the tubes during the lowering of the liquid level as well as by a specially suited apparatus for this purpose which operates according to the principle of communicating tubes there is provided the possibility of a good adhesion to the surface as well as the formation of a homogeneous layer at very little operating expense.

摘要： For the reduction of the ammonia content in the product gas of the hydrocyanic acid-methane-ammonia (BMA) process and accordingly to increase the yield the reaction gas mixture of this process is brought into contact with zeolite and the ammonia thereafter desorbed from the zeolite preferably again employed in the reaction step. If the desorption is carried out with a flushing gas such as the hydrocarbon used in the reaction then this mixture can be directly supplied again to the BMA reactor. Through this procedure the amount of ammonia previously lost to the process can again be made useful in the process itself.

摘要： 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+NH.sub.3 ". Otherwise the reaction conditions are the same as in the known BMA process.
摘要翻译： 用于生产氰化氢的已知氢氰酸 - 甲烷 - 氨（BMA）方法现在可以用液化气体进行，即在反应开始时通过存在另外的氢气来进行。 碳与氮和氢的原子比为1:1至7.1:1.33:1。 作为另外的氢，存在从反应“烃+ NH 3”出来的部分氢。 否则反应条件与已知的BMA方法相同。

摘要： In order to be independent of the situation in regard to methane and natural gas and at the same time to obtain a heating gas there is employed in the hydrocyanic acid-methane-ammonia process (the BMA process) in place of methane an alkanol or alkanediol having 2-4 carbon atoms, preferably ethyl alcohol, and this is reacted with ammonia in a C:N ratio of 0.8:1 to 2:1. Optionally additional hydrogen can be present.
