Claims (20)

1. 1. A reactor (10) for cracking hydrocarbons, comprising an inlet channel (11) for feeding hydrocarbons, a reaction zone (12) in which hydrocarbons are cracked to form reaction products consisting of smaller molecules, an energy supply means (13) configured to supply energy to said reaction zone (12), a membrane (14) configured to selectively pass a permeate consisting of at least a portion of the reaction products moving from the reaction zone (12) to a penetration zone (15) and separating from a retentate consisting of the remaining portion of the reaction products and unreacted hydrocarbons that remain in the reaction zone (12), an outlet channel (16) of the penetration zone (15) and an outlet channel (17) of the reaction zone (12), wherein the vibration excitation means (18) are configured to create vibration of the membrane (14), wherein the vibration excitation means (18) are configured to excite ultrasonic vibrations.
2. 2. The reactor according to claim 1, wherein the reactor (10) is designed with the possibility of cracking gaseous hydrocarbons.
3. 3. A reactor according to claim 1 or 2, in which the membrane (14) is designed with the possibility of selectively passing a permeate that includes molecules of only one chemical compound.
4. 4. A reactor according to claim 1 or 2, in which the membrane (14) is designed to selectively pass permeate, which includes molecules of two or more chemical compounds.
5. 5. A reactor according to claim 3 or 4, in which the membrane (14) is designed with the possibility of selectively passing the permeate separated from the retentate, which includes molecules of only one chemical compound.
6. 6. A reactor according to claim 3 or 4, in which the membrane (14) is designed with the possibility of selectively passing the permeate separated from the retentate, which includes molecules of two or more chemical compounds.
7. 7. A reactor according to one or more of the preceding claims, in which the membrane (14) is configured to selectively pass a permeate comprising H 2 .
