-3. (canceled)
A process for removing combustible non-volatiles from a reactor system, comprising:
- (A) depositing combustible non-volatiles during a first conversion step of duration t1, the combustible non-volatiles being deposited in first and second conduits of a first reactor, the first reactor being located within the reactor system;
- (B) during a first time interval of a second conversion step, the second conversion step having a duration t2 and the first time interval having a duration t2a,
- (a) conducting a first-reactant through the first conduit and a second-reactant through the second conduit;
- (b) heating the reactor system by exothermically reacting at least a portion of the second-reactant with (i) at least a portion of the combustible non-volatiles located in the second conduit and (ii) at least a portion of the first-reactant;
- and
- (C) during a second time interval of the second conversion step, the second time interval having a duration t2b,
- (a) conducting at least a portion of the second-reactant through the first conduit, and
- (b) reacting the second-reactant with at least a portion of the combustible non-volatiles located in the first conduit,
- (c) conducting the first-reactant through a third conduit,
- (d) conducting a second portion of the second reactant through the second conduit, and
- (e) heating the reactor system by exothermically reacting at least a portion of the second-reactant with (i) at least a portion of the combustible non-volatiles located in the first and/or second conduits and (ii) at least a portion of the first-reactant;
- wherein the first and second conduits comprise at least one channel in a reactor bed.
