2 . The reactor of claim 1 , wherein, within a plane oriented perpendicular to the longitudinal axis of the reactor, the plurality of catalyst conduits and the plurality of coolant conduits are distributed among a plurality of rows.

3 . The reactor of claim 2 , wherein each respective row of the plurality of rows comprises at least one catalyst conduit and at least one coolant conduit.

4 . (canceled)

5 . The reactor of claim 2 , wherein each respective row of the plurality of rows has a row axis, the row axis of each respective row being substantially perpendicular to the longitudinal axes of the catalyst conduits and coolant conduits within the row, wherein the catalyst conduits of each row are spaced apart relative to the row axis of the row, and wherein the coolant conduits of each row are spaced apart relative to the row axis of the row.

6 . The reactor of claim 5 , wherein, within the plane oriented perpendicular to the longitudinal axis of the reactor, the plurality of catalyst conduits and the plurality of coolant conduits are distributed among a plurality of columns, each respective column of the plurality of columns having a column axis substantially perpendicular to the longitudinal axes of the conduits within the column and to the row axes of the plurality of rows, wherein each respective column of the plurality of columns comprises at least one catalyst conduit and at least one coolant conduit, and wherein the catalyst conduits of each column are spaced apart relative to the column axis of the column, and wherein the coolant conduits of each column are spaced apart relative to the column axis of the column.

9 . (canceled)

10 . The reactor of claim 5 , wherein the plurality of catalyst conduits comprises at least one interior catalyst conduit that is positioned adjacent to at least three coolant conduits of the plurality of coolant conduits.

11 . (canceled)

12 . (canceled)

13 . (canceled)

14 . (canceled)

15 . The reactor of claim 1 , further comprising a grid positioned within the housing, the grid extending relative to the longitudinal axis of the reactor and being shaped to divide the housing into a plurality of compartments, wherein each respective compartment of the plurality of compartments contains at least one catalyst conduit and at least one coolant conduit, and wherein the grid is configured to thermally isolate the catalyst conduits and coolant conduits of each respective compartment from the catalyst conduits and coolant conduits of adjacent compartments.

16 . (canceled)

18 . The reactor of claim 15 , wherein at least one catalyst conduit within each respective compartment comprises a thermocouple configured to adjust coolant flow within the compartment.

19 . The reactor of claim 1 , further comprising at least one divider positioned within the housing, each divider of the at least one divider extending substantially perpendicularly relative to the longitudinal axis of the reactor, the at least one divider dividing the housing into a plurality of compartments positioned relative to the longitudinal axis of the reactor, wherein the at least one divider is configured to thermally isolate each compartment of the plurality of compartments from its adjacent compartments, and wherein at least one catalyst conduit within each respective compartment comprises a thermocouple configured to adjust coolant flow within the compartment.

20 . (canceled)

21 . The reactor of claim 19 , wherein at least one catalyst conduit within each respective compartment comprises a thermocouple configured to adjust coolant flow within the compartment.

22 . The reactor of claim 1 , wherein the housing has a first end and an opposed second end, the second end being spaced from the first end relative to the longitudinal axis of the reactor, and wherein the first end of the housing defines an inlet opening configured to receive at least one reactant, the inlet opening being positioned in fluid communication with the plurality of catalyst conduits.

23 . The reactor of claim 22 , wherein the second end of the housing defines an outlet opening configured to receive the reaction products produced within the reactor.

24 . The reactor of claim 23 , wherein the outer wall of the housing comprises a plurality of coolant valves, the plurality of coolant valves comprising at least one pair of axially spaced coolant valves, each pair of axially spaced coolant valves comprising a first coolant valve and a second coolant valve positioned between the first coolant valve and the outlet opening of the housing.
