摘要： Disclosed is a method for determining when to replace a guard bed material used to remove one or more catalyst poisons from a feed based on a parameter change in a process. A guard bed having a guard bed material is in fluid communication with a catalyst bed having a catalyst. At least three monitors are positioned in said guard bed or said catalyst bed and at least one parameter of the guard bed or catalyst bed is monitored. A feed component comprising one or more catalyst poisons is supplied to said guard bed or said catalyst bed. The feed is contacted with said guard bed material or said catalyst to remove at least a portion of a catalyst poison and to form a product which produces an increase or a decrease in said parameter. The monitored parameters are compared to determine when to replace the guard bed material.

摘要： Disclosed is a process for the production of alkylated aromatics by contacting a feed stream comprising an alkylatable aromatic, an alkylating agent and trace amounts of water and impurities in the presence of first and second alkylation catalysts wherein the water and impurities are removed in order to improve the cycle length of such alkylation catalysts. Water and a portion of impurities are removed in a dehydration zone. A first alkylation zone having a first alkylation catalyst which, in some embodiments is a large pore molecular sieve, acts to remove a larger portion of impurities, such as nitrogenous and other species, and to alkylate a smaller portion of the alkylatable aromatic compound. A second alkylation zone, which in some embodiments is a medium pore molecular sieve, acts to remove a smaller portion of impurities, and to alkylate a larger portion of the alkylatable aromatic compound.

摘要： A process is disclosed for producing an alkylaromatic compound in a multistage reaction system comprising at least first and second series-connected alkylation reaction zones, each containing an alkylation catalyst. A first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into the first alkylation reaction zone. The first and second alkylation reaction zones are operated under conditions of temperature and pressure effective to cause alkylation of the aromatic compound with the alkene in the presence of the alkylation catalyst, the temperature and pressure being such that the aromatic compound is at least partly in the liquid phase. The alkylation catalyst in the first alkylation reaction zone, which may be a reactor guard bed, has more acid sites per unit volume of catalyst than the alkylation catalyst in the second reaction zone.

摘要： A process is described for producing an alkylaromatic compound, in which a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkene are introduced into a first alkylation reaction zone comprising a first alkylation catalyst. The first alkylation reaction zone is operated under conditions effective to cause alkylation of the alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the vapor phase. A first effluent comprising the alkylaromatic compound and unreacted alkylatable aromatic compound is withdrawn from the first alkylation reaction zone and at least part of the unreacted alkylatable aromatic compound is treated to remove catalyst poisons therefrom and produce a treated unreacted alkylatable aromatic stream. At least part of the unreacted alkylatable aromatic compound and a third feed comprising said alkene is introduced into a second alkylation reaction zone comprising a second alkylation catalyst. The second alkylation reaction zone is operated under conditions effective to cause alkylation of the unreacted alkylatable aromatic compound by the alkene to produce said alkylaromatic compound, the conditions being such that the alkylatable aromatic compound is at least predominantly in the liquid phase. A second effluent comprising said alkylaromatic compound is withdrawn from the second alkylation reaction zone.
