Tail gas circulating process in acrylic acid production by propane one-step method
ActiveCN103193617AReduce consumptionLow conversion rateOrganic compound preparationCarboxylic compound preparationChemistryCarbon dioxide
The invention relates to a tail gas circulating process in acrylic acid production by chemical product materials through a propane one-step method. The tail gas circulating process is characterized by comprising the following steps of: entering steam, oxygen gas and nitrogen gas from a pre-mixer and then entering a charging mixer with propane; feeding the mixture to an oxidation reactor for carrying out chemical reaction after the materials are sufficiently mixed to generate acrylic acid and carbon monoxide, carbon dioxide, acetic acid and propylene by-products; exchanging heat for the reaction products through a first cooler, enabling the heat-exchanged reaction products to enter a washing tower, and using most of emitted gases from the tower top of the washing tower as circulating gases. The tail gas circulating process has the advantages that part of the propane-containing reaction tail gases are compressed and returned to the reactor by adopting the reaction tail gas circulating process for continuously participating in the oxidization reaction, so that the consumption of the propane is reduced. If the circulation volume is extremely large, by-product Co is accumulated in a vast manner and safety hazard is generated due to extremely high CO concentration; if the circulation volume is extremely small, the total yield of the reaction is reduced, and 85% of circulated gases are preferably fed to a compressor.

ActiveCN104974016AEliminate pollutionReduce the burden onOrganic compound preparationHydroxy compound preparationOrganic solventSolvent free
The invention relates to a method for preparing cinnamyl alcohol (COL) through cinnamaldehyde (CAL) hydrogenation. In a solvent-free system, Pt-(Ru)-Sn / TiO2 as a catalyst is used for catalyzing selective hydrogenation of CAL to prepare COL. The catalyst has relatively high activity on the hydrogenation of C=O bond of CAL and shows inertia on the hydrogenation of C=C bond of CAL and COL, and thus has high selectivity on the generated COL. When the reactants are nearly completely converted and Pt-(Ru)-Sn / TiO2 is used as the catalyst, the highest selectivity on COL reaches 93-95%. By adopting the method, the pollution of organic solvent is eliminated, the burden of the separation process is lightened, and the reaction control difficulty in large-scale production is reduced.
