Abstract
In one aspect, the inventive process comprises a process for pyrolyzing a hydrocarbon feedstock containing nonvolatiles in a regenerative pyrolysis reactor system. The inventive process comprises: (a) heating the nonvolatile-containing hydrocarbon feedstock upstream of a regenerative pyrolysis reactor system to a temperature sufficient to form a vapor phase that is essentially free of nonvolatiles and a liquid phase containing the nonvolatiles; (b) separating said vapor phase from said liquid phase; (c) feeding the separated vapor phase to the pyrolysis reactor system; and (d) converting the separated vapor phase in said pyrolysis reactor system to form a pyrolysis product.
Claims5
An apparatus for pyrolyzing a hydrocarbon feedstock containing nonvolatiles in a regenerative pyrolysis reactor system, said apparatus comprising:
- (a) a heater to heat a nonvolatile-containing hydrocarbon feedstock to a temperature sufficient to form a vapor phase that is essentially free of nonvolatiles and a liquid phase containing the nonvolatiles;
- (b) a separator to separate the vapor phase from the liquid phase;
- and
- (c) a regenerative pyrolysis reactor system to receive the separated vapor phase, heat and convert the separated vapor phase in said pyrolysis reactor system to form a pyrolysis product.
An apparatus for the manufacture of a hydrocarbon pyrolysis product from a hydrocarbon feed using a regenerative pyrolysis reactor system, the apparatus comprising:
- (a) a heater to heat a nonvolatile-containing hydrocarbon feedstock to a temperature sufficient to form a vapor phase that is essentially free of nonvolatiles and a liquid phase containing the nonvolatiles;
- (b) a separator to separate the vapor phase from the liquid phase;
- and
- (c) a regenerative pyrolysis reactor system to receive the separated vapor phase and convert the separated vapor phase in said pyrolysis reactor system to form a pyrolysis product, the regenerative pyrolysis reactor system including;
- (i) a first reactor comprising a first end and a second end;
- and
- (ii) a second reactor comprising primary end and a secondary end, the first and second reactors are oriented in a series flow relationship with respect to each other,
- wherein the first reactor comprises a first channel for conveying a first reactant through the first reactor and a second channel for conveying a second reactant through the reactor.
