Title: Improvements in or relating to the bittering of beer
IPC: C12C7/20
Filed: 1957-11-27
Abstract: In the bittering of beer, iso-compounds, prepared by subjecting hops or resins extracted from hops to alkaline isomerization, are added to the wort at any stage after the wort has been boiled and the break removed therefrom, preferably during or after fermentation.  The hop a -acids are converted into the iso-compounds by boiling them with a dilute aqueous alkaline solution with pH above 9, and normally between 11 and 13 e.g. N/10 aqueous sodium carbonate or N/15 aqueous sodium hydroxide.  The alkaline isomerization mixture is acidified with mineral acid followed by extraction with light petroleum or ether which is then removed by distillation at a relatively low temperature.  The residue thus obtained is dissolved in a minimum volume of dilute aqueous sodium carbonate solution or of ethyl alcohol giving a solution which contains about 90% of the bittering potential of the original hops.  The hops may be thus treated immediately after picking.

Title: Thermal cracking process
IPC: C10G9/16
Filed: 1966-08-30
Abstract: In a process for thermally cracking hydrocarbons by passing them in admixture with steam through a multiplicity of tubes arranged in parallel in a cracking furnace, the tubes being subjected to radiant heat sufficient to cause the reactants within the tube to have a temperature of 1200-1600 DEG  F., a minor proportion of the tubes are taken offstream by cutting off hydrocarbon feed and passing steam and/or water through said tubes in amount sufficient to maintain the tube temperature at essentially the same level as in the onstream tubes and to effect removal of coke deposit on the interior of the tubes, and thereafter returning said tubes to normal onstream operation. The tubes may pass through a convection-heated section prior to the radiant section, in which case the steam temperature at the cross-over point is at least 700 DEG  F.  One tube at a time may be decoked in this way, or more than one in which case the change-over may proceed successively.
