Process and apparatus for chemical conversion
A process and reactor for chemical conversion is taught. The process allows the selective breaking of chemical bonds in a molecule by use of fast rise alternating current or fast rise pulsed direct current, each fast rise portion being selected to have a suitable voltage and frequency to break a selected chemical bond in a molecule. The reactor for carrying out such a process includes a chamber for containing the molecule and a generator for generating and applying the selected fast rise current.
1. An apparatus for breaking a chemical bond in a molecule, the molecule being in a gas or vapor state, the apparatus comprising:
a chamber for containing the molecule having two separate electrodes;
an electrical signal generator that generates a periodic waveform having a fast rising leading edge, wherein the fast rising leading edge is selected to at least partially ionize the molecule to break the chemical bond.
2. The apparatus as claimed in claim 1 wherein the fast rising leading edge includes a portion having a constant slope.
3. The apparatus as claimed in claim 1 wherein the suitable voltage includes a range of voltages having an adjustable voltage increase rate.
4. The apparatus as claimed in claim 3 wherein the voltage increase rate of the fast rising leading edge is adjusted to optimize the break down of the chemical bond.
5. The apparatus as claimed in claim 4 wherein a voltage increase rate of the fast rising leading edge is substantially equal to 6.6×10 6 volts/second, to thereby produce ozone gas from molecules of oxygen.
6. The apparatus as claimed in claim 4 wherein the voltage increase rate of the fast rising leading edge is substantially equal to 234×10 6 volts/second, to thereby produce ozone gas from molecules of oxygen.
7. The apparatus as claimed in claim 4 wherein the voltage increase rate of the fast rising leading edge is substantially equal to 233.5×10 6 volts/second, to thereby produce ozone gas from molecules of oxygen.
8. The apparatus as claimed in claim 4 wherein the voltage increase rate of the fast rising leading edge is substantially equal to 384.6×10 6 volts/second, to thereby produce bromine gas from molecules of Halon 1301 (CF 3 Br).
9. The apparatus as claimed in claim 4 wherein the voltage increase rate of the fast rising leading edge is substantially equal to 386×10 6 volts/second, to thereby produce bromine gas from molecules of Halon 1301 (CF 3 Br).
10. The apparatus as claimed in claim 1 wherein the molecule is oxygen and at least a portion of the oxygen is ionized in the chamber to form ionized oxygen, at least a portion of the ionized oxygen recombines to form ozone and the apparatus further comprises an outlet in fluid communication with the chamber for receiving the ozone.
11. The apparatus of claim 1 , wherein a slope of the fast rising leading edge is selected to represent an active frequency of the chemical bond being broken.
