Method and device for the production of flammable gases by catalytic cracking of liquid or gaseous forms

Hydrocarbons

The invention relates to an improvement in manufacturing flammable gases through catalytic cracking of liquid or gaseous hydrocarbons.

It is known that the catalytic cracking of hydrocarbons takes place according to one of the following methods:

Catalytic steam cracking with external heating:

The device consists of tubes arranged in an oven and filled with catalyst; the su treated

Hydrocarbon

Hydrocarbon traverses water vapor after adding τοη and / or another flowable medium the catalyst

eator, the endothermic cracking reaction being gate itself goes; the corresponding calorie intake is provided by external Warming delivered.

Endothermic catalytic cracking with air and / or oxygen:

The device consists of a chamber containing the catalyst; the one with air and / or oxygen and / or another flowable medium to be treated hydrocarbon passed through the catalyst, whereby the cracking reaction takes place, which is endothermic thanks to the right choice of media that react with one another

öemäss of the invention, now two or more of the above-mentioned devices are so connected in B _e ihe that the second and the following Krackungen in the presence of exiting at the first cracking flowing media carried ·

The reason for this goal is to be found in the fact that As a rule, certain of the flowable media must be used in excess »in particular the water

steam, and that the rorhandene at the first Kraokung The surplus used for the closing fractions so that the Oesaatttberschuse of flowable media can be rerredert ι the heat yield is thereby increased because of the loss of water due to a lowering this excess flowable media rerringert will·

The drawing shows an example of an embodiment the device to be used according to the invention. In the Animal figures in the drawing refer to the same reference series and the same parts
