초록 ▼

A process and apparatus capable of cracking hydrocarbon to produce a reaction product containing a high proportion of ethylene. A hydrocarbon such as naphtha is vaporized and admixed with superheated steam at high temperature in a mixing device. The resulting hydrocarbon-steam mixture is passed through a reaction zone consisting of a reactor conduit which extends through a passageway defined in a radiation block structure. Heating gases at extremely high temperatures are directed through the passageway, co-currently with the hydrocarbon-steam mixture, to produce a desirable heat flux for the cracking reaction. A short residence time in the reactor conduit is maintained to prevent undesirable side reactions.

대표청구항 ▼

A process for cracking a hydrocarbon composition which comprises the steps of: passing steam through a conduit enclosed by a radiation block structure, the structure defining a gas passage which surrounds the steam conduit; flowing heating gases through the gas passage to superheat the steam to a temperature of from about 1000°C. to 1500°C.; mixing the hydrocarbon composition with the superheated steam; passing the resulting hydrocarbon-steam mixture through a reactor conduit which extends through and is enclosed by a radiation block structure, the structure defining a gas passage which surrounds the reactor conduit; flowing heating gases through the gas passage, in contact with the reactor conduit, and in a direction co-current with the flow of the hydrocarbon-steam mixture through said reactor conduit, to heat said hydrocarbon-steam mixture to a temperature of from about 700°C. to 1000°C.; causing the heated hydrocarbon composition to undergo a cracking reaction while in the reactor conduit; and passing the hot reaction product from the reactor conduit into a heat exchanger for quenching said reaction product.
