    Abstract: PURPOSE: To reuse a nylon 6 container as nylon raw material without washing by using nylon 6 packaging material having low oxygen permeability. CONSTITUTION: A caprolactam packaging material is composed of nylon 6. Its envelop is formed by polyethylene, a polypropylene woven material or a polyethylene tape, and one or a plurality of layers of paper material, non-woven fabric or woven fabric is used as the outermost envelop. Whereby the humidity can be sufficiently cut, and the sufficient and effective protection to the mechanical damage can be obtained. As polyethylene is used as the envelope, the material can be reused without washing. Further a nylon 6 sheet can prevent the intrusion of the atmospheric oxygen, so that the contents can be protected for anti-contamination.

    Abstract: PURPOSE: To provide a regenerating method for effectively recovering a noble metal used for synthesizing a hydroxylammonium salt by catalytic reduction of nitrogen oxide with hydrogen, particularly a platinum-supported catalyst without requiring an additional process. CONSTITUTION: This catalyst regenerating method is characterized by treating a noble metal catalyst used for catalytic reduction of nitrogen oxide with hydrogen in an aqueous alkaline solution having a pH higher than 9.
