Abstract

A system for producing chemicals, such as, ethylene or gasoline, at high temperature (above 1100 degrees C.) having a feedstock source. The system includes a chemical conversion portion connected with the feedstock source to receive feedstock and convert the feedstock to ethylene or gasoline. The conversion portion includes a coil array and a furnace that heats the feedstock to temperatures in excess of 1100° C. or 1200° C. or even 1250° C. or even 1300° C. or even 1400° C. A method for producing chemicals, such as ethylene or gasoline, at high temperature.

Abstract

An assembly including a ceramic body. The assembly comprises a tungsten coupling attached to the ceramic body with a first joint that forms a first helium tight seal between the ceramic body and the tungsten coupling and where the first helium tight seal maintains its integrity at a temperature over 400° C. The assembly includes a metal body attached to the tungsten coupling with a second joint that forms a second helium tight seal between the metal body and the tungsten coupling and where the second helium tight seal maintains its integrity at a temperature over 400° C. A method. A mixture. A coupling.
