摘要： PROBLEM TO BE SOLVED: To obtain a new catalyst system having good selectivity at the beginning of reaction, high total productivity and a long service life of the catalyst itself. SOLUTION: The catalyst system consists of vanadium oxide, bismuth oxide and a magnesium-base carrier and attains the oxidative dehydrogenation of an alkyl aromatic (particularly ethylbenzene) or a paraffin to the corresponding alkenyl aromatic (particularly styrene) or the corresponding olefin. Vanadium expressed as V2O5 occupies 1-15 wt.%, preferably 2-10 wt.% of the total amount (100 wt.%) of the catalyst system, bismuth expressed as Bi2O3 occupies 2-30 wt.%, preferably 5-25 wt.% and the carrier occupies the balance.

摘要： Process for separating mixtures of hydrocarbon isomers in gas phase on molecular sieves characterized in that it comprises the following steps: (a) feeding the mixtures of hydrocarbon isomers to a column, or several columns, having the function of primary adsorption column, wherein part of the isomers with a greater selectivity towards the molecular sieves, are adsorbed; (b) feeding the effluent from the primary adsorption column(s) to a column, or several columns, having the function of secondary adsorption column, wherein the remaining part of the isomers with a greater selectivity towards the molecular sieves, are adsorbed, and from which a stream is discharged containing isomers with a lower selectivity towards the molecular sieves, and the desorbing agent already present in the column; (c) feeding the desorbing agent to a column, or several columns, having the function of desorption column, from which a stream is discharged containing the isomers with a greater selectivity towards the molecular sieves, and the desorbing agent itself; (d) feeding the stream containing the isomers with a lower selectivity towards the molecular sieves, and the desorbing agent, leaving the column(s) having the function of secondary adsorption column, to a distillation unit for the recovery of the desorbing agent to be recycled to the column(s) having a desorption function (e) feeding the stream containing the isomers with a greater selectivity towards the molecular sieves and the desorbing agent, leaving the column(s) having the function of desorption column, to another distillation unit for the recovery of the desorbing agent to be recycled to the column(s) having a desorption function steps (a), (b) and (c) being effected by means of three phases and a number of three or a multiple of three columns having fixed molecular sieve beds, so that from one phase to another, these columns pass alternatively in sequence from functions of secondary adsorption column to functions of primary adsorption column, to functions of desorption column.
