摘要： A process for the alkylation of alkane with olefin or olefin precursor such as an oligomer of tertiary olefin comprising contacting a liquid system comprising acid catalyst, isoparaffin and olefin in concurrent downflow into contact in a reaction zone with a disperser mesh under conditions of temperature and pressure to react said isoparaffin and said olefin to produce an alkylate product is disclosed. Preferably, the liquid system is maintained at about its boiling point in the reaction zone. Unexpectedly, the olefin oligomers have been found to function as olefin precursors and not as olefins in the reaction. Thus, for example, a cold acid alkylation using an oligomer of isobutene (principally dimer and trimer) with isobutane produces isooctane with the isobutane reacting with the constituent isobutene units of the oligomers on a molar basis. The product isooctane is essentially the same as that produced in the conventional cold acid process.

摘要： A fractal fluid distribution system for use in a vessel is described wherein two phases are distributed separately and then finally mixed in a set of stacked fractal plates which are off set from one another by rotation around a central axis. Each of the two phases is fed from the top of the vessel. The flow paths of each individual phase have approximately the same length. A header is provided to allow feeding the two phases separately without interference with the final distribution outlets.

摘要： A process for the dimerization of isobutene wherein tertiary butyl alcohol is used to enhance the selectivity of the catalyst to the dimer is disclosed wherein the tertiary butyl alcohol is removed from the diisobutene product by water wash. The water/TBA stream is then subjected to reextraction to remove the TBA for recycle to the dimerization reactor. The dimerization is preferably carried out in a reactor wherein the pressure is controlled to maintain the reaction mixture at is boiling point. Additional dimerization is carried out in a distillation column reactor that acts as a debutanizer to separate the unreacted isobutene form the product and the tertiary butyl alcohol.
