PROCESS FOR PREPARING ACROLEIN BY CATALYTIC OXIDATION OF GASEOUS PROPYLENE |
摘要 |
The invention relates to a process for producing acrolein by catalytic gas-phase oxidation of propene with air in the presence of steam and inert gas or waste gas from the reaction, the feed stocks being passed in defined quantitative ratios at 300 - 380 DEG C and 1.4 - 2.2 bar over a catalyst containing the MoFeCoNiBiP(As)K(Rb,Cs)SmSiO element combination in the form of a bed of individual particles, the catalyst particles meeting defined geometrical conditions and a number of essential physical-chemical parameters, and a specific loading of 2 - 8 mol of propene/dm<3> of catalyst bed/hour being set. |
