Process for the determination of the behaviour in thermal cracking of h

摘要

P the invention relates to the determination of the behaviour in thermal cracking of raw materials for cracking furnaces industrial. / p & & p & according to this process, a certain quantity of the raw material with an inert gas is heated in an oven at least until the limit of thermal cracking. Then the cracking products are analysed. It is injected into a steam chamber is heated such a quantity of the raw material to be examined, that this chamber may contain the sample to be vaporized state. After it is driven as a plug, the raw material is vaporized and heated in the furnace by means of an inert gas, so that the partial pressure of the raw material for the temperature prevailing in the furnace has a value, which is at the same as that in the industrial furnace of cracking in which it is used, the raw material to be examined. The furnace is constituted by a narrow duct of a catalytically inactive screw - to - screw of the cracks. / p & & p & this process makes it possible to optimize the operation of the cracking furnaces industrial. / p
