METHOD OF PRODUCING CIRCULAR OXIDE COMPACTED MATERIAL |
摘要 |
FIELD: process engineering.SUBSTANCE: invention relates to powder metallurgy, particularly, to production of circular oxide compacted article. It can be used for production of catalyst stationary bed used in shell-and-tube reactor pipes. Powder material containing at least one metal compound to be converted into metal oxide by heat treatment, or at least one metal oxide , or at least one metal oxide and at least one metal compound, are placed in loading chamber. Mechanical compaction is performed to preform ring-like article with side surface shaped to truncated cone expanding upward. Preformed article is heat treated at ?100°C to destruct and/or chemically convert the article components with production of gas compound and final ring-like oxide article.EFFECT: higher quality of finished articles.50 cl, 10 dwg, 5 ex |
