Abstract

The present disclosure relates to reactor components and their use, e.g., in regenerative reactors. A process and apparatus for utilizing different wetted areas along the flow path of a fluid in a pyrolysis reactor, e.g., a thermally regenerating reactor, such as a regenerative, reverse-flow reactor, is described.

First claim

What is claimed is:

1. A hydrocarbon pyrolysis reactor, the reactor comprising:
a housing enclosing an interior region and having one or more insulation components disposed adjacent to the housing;
a plurality of input means configured to manage the flow of one or more streams into the interior region from a location external to the interior region;
one or more process flow components configured to manage the flow of fluids through the interior region, wherein the one or more process flow components comprise (i) a first bed packing having a first plurality of flow passages and a first wetted area a v1 ; (ii) a second bed packing having a second plurality of flow passages and a second wetted area a v2 , wherein the ratio of the second wetted area a v2 to the first wetted area a v1 is ≦0.75; and (iii) a third bed packing having a third plurality of flow passages and a third wetted area a v3 , wherein the ratio of the third wetted area a v3 to the second wetted area a v2 is ≦0.75.

2. The hydrocarbon pyrolysis reactor of claim 1 , further comprising a mixing means disposed between the first bed packing and the second bed packing and/or disposed adjacent to the second bed packing.

3. The hydrocarbon pyrolysis reactor of claim 2 , wherein the mixing means comprises one or more different plates.

4. The hydrocarbon pyrolysis reactor of claim 2 , wherein the mixing means consisting essentially of a gap.

5. The hydrocarbon pyrolysis reactor of claim 1 , wherein (i) the first bed packing is a first monolith and the first wetted area a v1 is in a range of 500 m −1 to 4000 m −1 and (ii) the second bed packing is a second monolith and the second wetted area a v2 is in the range of 100 m −1 to 1000 m −1 .

6. The hydrocarbon pyrolysis reactor of claim 1 , wherein the first bed packing is a first monolith and the first wetted area a v1 is in a range of 800 m −1 to 3000 m −1 and the second bed packing is a second monolith and the second wetted area a v2 is in the range of 100 m −1 to 800 m −1 .
