There is described a method of using a feedstock gas reactor. Reaction of feedstock and combustion gases in the reactor produces hydrogen through pyrolysis of the feedstock gas. At least some of a mixed product stream extracted from the reactor may be recycled to the reactor to drive further pyrolysis of the feedstock gas. A portion of the recycled mixed product stream may be recirculated back to a combustion chamber of the reactor, and a portion of the recycled mixed product stream may be recirculated back to a reaction chamber of the reactor.

A hydrogen peroxide removing apparatus for removing hydrogen peroxide contained in water to be processed includes: anode and cathode; and hydrogen peroxide removal chamber provided between anode and cathode and at least partially filled with a metal catalyst with hydrogen peroxide decomposition ability, wherein a DC voltage is applied between anode and cathode.

It is an object to provide a regenerated denitration catalyst whose denitration performance is restored compared with a denitration catalyst before use, utilizing a spent denitration catalyst, and a method for manufacturing the same. In a regenerated denitration catalyst according to the present disclosure, a spent denitration catalyst including a first titanium oxide as a main component, and a second titanium oxide are mixed. The spent denitration catalyst is already used in a denitration reaction in which nitrogen oxides in a gas are decomposed into nitrogen and water using a reducing agent. The second titanium oxide has a larger specific surface area per unit weight than the first titanium oxide. A content of the second titanium oxide based on a total weight of the first titanium oxide and the second titanium oxide is preferably 10% by weight or more and 90% by weight or less.
