摘要： Acetylenes and dienes in a stream containing hydrogen, methane, C2-C6 olefins and paraffins, C2-C6 acetylenes and dienes, benzene, toluene, xylenes, and other C6+ components are hydrogenated in a downflow boiling point reactor wherein the heat of reaction is absorbed by the liquid in the reactor which produces a vapor. Besides the feed to the reactor there is a recirculating stream which is fed at a rate sufficient to ensure that the catalyst particles within the reactor are wetted. A third stream, which is provided from a second downstream liquid/vapor separator from partially condensed vapor from the first downstream liquid/vapor separator corresponding to the mass evaporated in the reactor, is fed to the reactor. The composition of the third stream controls the steady state composition of the liquid flowing through the reactor.

摘要： A process for the production of diisobutene is disclosed wherein tertiary butyl alcohol is dehydrated to isobutene in a distillation column reactor containing an acid cation exchange resin catalyst in the form of catalytic distillation structure. The isobutene reacts with itself in the presence of the catalyst to form primarily diisobutene which is removed as bottoms from the distillation column reactor with the bulk of the water. Unreacted isobutene along with an azeotrope of water is removed as overheads with the water being separated and removed from the unreacted isobutene. A portion or all of the unreacted isobutene may be returned to the distillation column reactor as reflux.

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 liquid phase process for oligomerization of C.sub.4 and C.sub.5 isoolefins or the etherification thereof with C.sub.1 to C.sub.6 alcohols wherein the reactants are contacted in a reactor with a fixed bed acid cation exchange resin catalyst at an LHSV of 5 to 20, pressure of 0 to 400 psig and temperature of 120.degree. to 300.degree. F. Wherein the improvement is the operation of the reactor at a pressure to maintain the reaction mixture at its boiling point whereby at least a portion but less than all of the reaction mixture is vaporized. By operating at the boiling point and allowing a portion of the reaction mixture to vaporize, the exothermic heat of reaction is dissipated by the formation of more boil up and the temperature in the reactor is controlled.
