摘要： A process for dimerizing olefins in the presence of a catalyst, a hydrocarbon feedstock containing C4 to C6 isoolefins is subjected to dimerization. The process comprises the steps of contacting the C4 to C6 isoolefins at conditions conducive to dimerization with a catalytic material comprising an acidic mesoporous molecular sieve, the catalytic material being thermally stable at a temperature of at least 900° C., and carrying out the contacting step essentially in the absence of butadiene and water in the feedstock. By means of the invention, the dimerization process can be operated over extended periods of time with prolonged maintenance intervals.

摘要： A portable PC combination or attache case for carrying a PC and a printer and when placed on a planar surface is positioned so that one side edge of each is along a common hinged side and when the case is in the open position in front of the user, the PC and the printer are ready for use, with their front edges toward the user. The PC, equipped with an opening cover containing a conventional screen faces a user in the open condition of the cover, and the printer are both firmly attached to a bottom section and a cover section, respectively. Inside the case a spiral spring containing cables connecting the PC and the printer and overlie the hinge connection.
