Vapor phase catalytic oxidation of propylene to acrylic acid |
摘要 |
An improved method for manufacturing acrylic acid by vapor phase oxidation of propylene in a single step or reaction stage using as solid phase oxidant a mixture of two particulate solids comprising a bismuth molybdate multimetal oxide, (e.g., Mo12Co3.5Bi1.1Fe0.8W0.5Si1.4K0.05Ox) and a molybdenum vanadate multimetal oxide (e.g., Mo12V4.8Sr0.5W2.4Cu2.2Ox). Such a process is advantageously carried out in a recirculating solids reactor system wherein the particulate mixture of solids in an oxidized state reacts with a feed gas containing propylene in a vertical riser reactor and after separation from the acrylic acid gaseous product the particulate mixture of solids in a reduced state is regenerated by contact with an oxygen containing gas in a separate regeneration reactor before recirculation to the riser for further reaction. |
