摘要: A mixed metal oxide, which may be an orthorhombic phase material, is regenerated, selectively enriched or selectively poisoned as a catalyst to reduce catalyst aging for the production of unsaturated carboxylic acids, or unsaturated nitrites, from alkanes, or mixtures of alkanes and alkenes, by contacting said mixed metal oxide with a an oxidizing gas such as oxygen, air, steam and combinations thereof is permitted to flow through the catalyst in a regenerator at a temperature of from 300° C. to 600° C. to form said regenerated catalyst.
摘要翻译: 可以是正交相材料的混合金属氧化物被再生,选择性地富集或选择性地中毒作为催化剂,以减少催化剂老化,用于从烷烃或烷烃和烯烃的混合物生产不饱和羧酸或不饱和亚硝酸盐, 通过使所述混合金属氧化物与氧气,空气,蒸汽及其组合的氧化气体接触,可以在300℃至600℃的温度下在再生器中流过催化剂以形成所述再生催化剂 。
