Definitions

  • the annular matrix of the regenerator is readily fabricated, compartmented and strengthened by winding glassy ceramic cloth on a core and forming a line of ceramic cement across the face, rotating the core by a fraction of a revolution, and repeating.
  • the Metherox Process Figure 1 illustrates diagrammatically the preferred steps of a preferred embodiment utilizing the invention.
  • relatively pure oxygen in line 10 - - compressed to at least reaction pressure which is preferably between about 20 and about 200 atmospheres absolute (ata), and usually between about 50 and about 100 ata - - is mixed with recycle gas delivered by blower 11 and fresh hydrocarbonaceous feed in line 12.
  • reaction pressure which is preferably between about 20 and about 200 atmospheres absolute (ata)
  • this feed would comprise methane (and for higher alcohols, the corresponding hydrocarbon).
  • isobutane is fed along with methane.
  • Heat is further usefully recovered from these gases in line 19 by their serving to provide heat in necessary reboil duty in other steps in the process, as indicated by heat exchange loops 20, 21, 22, 23 (supplemented where or if necessary by steam or other hot medial . During this further cooling, water vapor and some methanol will generally condense, further recovering (latent), heat.
  • the temperature at the top of vessel 25 may be adjusted so that the net make of the various products and byproducts, comprising formaldehyde and isobutanol, is carried overhead into line 34, along with the gases introduced to vessel 25 via line 32; or alternatively a small liquid stream (not shown) may be taken from line 31 and passed directly to the catalytic reaction zone 33 of vessel 14; or, if desired, this minor product may be separately removed from the system.
