Abstract:
1. A method for pyrolyzing a pyrolysis feed in a thermal pyrolysis regenerative reactor to produce a pyrolyzed hydrocarbon product, comprising the steps of: providing a pyrolysis feed having (i) a liquid portion and (ii) a vapor portion, the pyrolysis feed comprising a hydrocarbon component containing greater than 0.010 wt. % of a non-volatile component based on total weight of the pyrolysis feed, and wherein the liquid portion is sufficient to maintain the non-volatile component in the liquid portion; passing the pyrolysis feed to a first end of the regenerative reactor; vaporizing at least a portion of the liquid portion of the pyrolysis feed at the first end of the regenerative reactor; pyrolyzing at least a portion of the hydrocarbon component under thermal pyrolysis condition to produce the pyrolyzed hydrocarbon product that comprises acetylene; conducting away the pyrolyzed hydrocarbon product from a second end of the regenerative reactor; removing from the regenerative reactor at least a portion of the non-volatile component via the first end of the regenerative reactor; interrupting production of the pyrolyzed hydrocarbon product; introducing a combustion reactant to the second end of the regenerative reactor; reacting the combustion reactant in the regenerative reactor to form combustion products; flowing combustion products toward the first end of the regenerative reactor; and conducting away at least a portion of the non-volatile components deposited in the regenerative reactor with the combustion products at the first end of the regenerative reactor.
