Production of unsaturated hydrocarbons and apparatus therefor

Claim 2

APPARATUS FOR THE PRODUCTION OF UNSATURATED HYDROCARBONS WHICH COMPRISES, IN COMBINATION, A REACTOR HAVING A CONSTRICTED PASSAGEWAY THERETHROUGH THE ENDS OF SAID PASSAGEWAY HAVING A LARGER CROSS-SECTIONAL AREA THAN INTERMEDIATE PORTIONS THEREOF; A REGENERATIVE FURNACE CONNECTED TO EACH END OF SAID PASSAGEWAY; AT LEAST TWO SPACED APART SETS OF FLUID INLET MEANS, SAID MEANS OF EACH SET BEING OPPOSITELY POSITIONED IN AND COMMUNICATING WITH SAID PASSAGEWAY OF SAID REACTOR AND EACH OF SAID SETS OF FLUID INLET MEANS BEING INDEPENDENTLY ADJUSTABLE; AND FLUID INLET AND WITHDRAWAL MEANS ATTACHED TO THE OUTER END OF EACH OF SAID REGENERATIVE FURNACES.

Claim 3

A PROCESS FOR THE PRODUCTION OF ACETYLENE WHICH COMPRISES HEATING A STREAM OF OXIDANT BY PASSING THE SAME THROUGH A FIRST REGENERATOR; PSSING THE HEATED OXIDANT INTO AN ELONGATED REACTOR; INCREASING THE VELOCITY OF SAID HEATED OXIDANT IN SAID REACTOR; SIMULTANEOUSLY INTRODUCING A PLURALITY OF LATERAL STREAMS OF FUEL INTO THE ACCELERATED STREAM OF OXIDANT; RAPIDLY AND UNIFORMLY MIXING THE OXIDANT AND FUEL SO AS TO FORM A COMBUSTIBLE MIXTURE; BURNING SAID COMBUSTIBLE MIXTURE IN A COMBUSTION ZONE; PASSING A STREAM OF COMBUSTION PRODUCTS FROM SAID COMBUSTION ZONE INTO A REACTION ZONE; SIMULTANEOUSLY THEREWITH INTRODUCING A PLURALITY OF LATERAL STREAMS OF A GASEOUS HYDROCARBON FEED INTO SAID STREAM OF COMBUSTION PRODUCTS; RAPIDLY AND UNIFORMLY MIXING SAID COMBUSTION PRODUCTS AND SAID HYDROCARBON FEED IN SAID REACTION ZONE; UTILIZING THE HEAT OF SAID COMBUSTION PRODUCTS TO CRACK SAID HYDROCARBON FEED; MEASURING THE CONCENTRATION OF A KEY PORDUCT CONTAINED IN THE PRODUCT STREAM REMOVED FROM SAID REACTION ZONE; VARYING THE AMOUNT OF REACTANTS INTRODUCED INTO SAID REACTOR SO AS TO MAINTAIN THE CONCENTRATION OF SAID KEY PRODUCT AT A PREDETERMINED VALUE, THEREBY OBTAINING A HIGH YEILD OF ACETYLENE; PASSING THE RESULTING REACTION PRODUCTS INTO A SECOND REGENERATOR FOR RAPID QUENCHING TO A TEMPERATURE AT WHICH SAID ACETYLENE IS STABLE; TERMINATING THE SUPPLY OF OXIDANT TO SAID FIRST REGENERATOR; INTRODUCING A STREAM OF OXIDANT INTO SAID SECOND REGENERATOR; AND CONTINUING THE STEPS OF THE PROCESS AS ENUMERATED HEREINABOVE UTILIZING SAID SECOND REGENERATOR HEAT SAID OXIDANT AND SAID FIRST REGENERATOR TO QUENCH SAID REACTION PRODUCTS.

Claim 4

A PROCESS FOR THE PRODUCTION OF ACETYLENE WHICH COMPRISES HEATING A STREAM OF OXIDANT BY PASSING THE SAME THROUGH A FIRST REGENERATOR; PSSING THE HEATED OXIDANT INTO AN ELONGATED REACTOR; INCREASING THE VELOCITY OF SAID HEATED OXIDANT IN SAID REACTOR; SIMULTANEOUSLY INTRODUCING A PLURALITY OF LATERAL STREAMS OF FUEL INTO THE ACCELERATED STREAM OF OXIDANT; RAPIDLY AND UNIFORMLY MIXING THE OXIDANT AND FUEL SO AS TO FORM A COMBUSTIBLE MIXTURE; BURNING SAID COMBUSTIBLE MIXTURE IN A COMBUSTION ZONE; PASSING A STREAM OF COMBUSTION PRODUCTS FROM SAID COMBUSTION ZONE INTO A REACTION ZONE; SIMULTANEOUSLY THEREWITH INTRODUCING A PLURALITY OF LATERAL STREAMS OF A GASEOUS HYDROCARBON FEED INTO SAID STREAM OF COMBUSTION PRODUCTS; RAPIDLY AND UNIFORMLY MIXING SAID COMBUSTION PRODUCTS AND SAID HYDROCARBON FEED IN SAID REACTION ZONE; UTILIZING THE HEAT OF SAID COMBUSTION PRODUCTS TO CRACK SAID HYDROCARBON FEED; MEASURING THE CONCENTRATION OF A KEY PORDUCT CONTAINED IN THE PRODUCT STREAM REMOVED FROM SAID REACTION ZONE; VARYING THE AMOUNT OF REACTANTS INTRODUCED INTO SAID REACTOR SO AS TO MAINTAIN THE CONCENTRATION OF SAID KEY PRODUCT AT A PREDETERMINED VALUE, THEREBY OBTAINING A HIGH YEILD OF ACETYLENE; PASSING THE RESULTING REACTION PRODUCTS INTO A SECOND REGENERATOR FOR RAPID QUENCHING TO A TEMPERATURE AT WHICH SAID ACETYLENE IS STABLE; TERMINATING THE SUPPLY OF OXIDANT TO SAID FIRST REGENERATOR; INTRODUCING A STREAM OF OXIDANT INTO SAID SECOND REGENERATOR; AND CONTINUING THE STEPS OF THE PROCESS AS ENUMERATED HEREINABOVE UTILIZING SAID SECOND REGENERATOR HEAT SAID OXIDANT AND SAID FIRST REGENERATOR TO QUENCH SAID REACTION PRODUCTS.
