 Abstract
The heat transfer between effluent and walls of fixed particles beds reactors is influenced by many factory which depend on the characteristics of particles beds and fluid conditions.
In many industrial types of equipment in the chemical and petrochemical industry for heat transfer there are used spherical particles beds.
This paper presents an experimental study for the determination of heat transfer coefficient between the interior of the reactor and reactor wall.

 Rezumat
În reactoarele cu straturi fixe de catalizator, transferul de căldură între efluent şi pereţii rectoarelor este influenţat de mai mulţi factori care depind de caracteristicile straturilor de particule şi condiţiile efluentului.In multe utilaje din industria chimică şi petrochimică pentru îmbunătăţirea transferului de căldură se folosesc particule sferice.Lucrarea prezintă un studiu experimental privind calculul coeficientului de transfer de căldură între interiorul şi peretele reactoarelor.
