Abstract
Винахід може використовуватись в хімічній, біотехнологічній та інших галузях промисловості. Розроблений спосіб проведення двофазних реакцій з сумісною подачею газової і рідкої фаз в реактор, в якому забезпечуються траєкторії просування газової і рідкої фаз, поліпшуючі умови безпосереднього контакту між цими фазами. При цьому оптимізуються умови масо- і теплообміну і, тим самим, підвищується продуктивність процесу і зменшується споживана потужність.
