Starting the run

In experiment HGR-13, the commercial grade precipitated nickel catalyst was in a reduced and stabilized condition when it was charged into the reactor. No special activation treatment was needed. It was, however, kept under hydrogen at all times until the temperature and pressure of the system were brought to synthesis conditions, at which time the synthesis feed gas was gradually fed into the system to start the run. 

Minor Recommendation 2 Codify that the decision of any court on the same patent being litigated by the first generic applicant constitutes a court decision sufficient to start the running of the 180-day exclusivity. 

The catalyst was pretreated by steaming for B h at 1 atm pressure and 500 C, then heated in flowing helium for 2 h at the reaction temperature. The helium stream then was passed through the cumene reservoir to start the run. The run was stopped when the coke level reached 5 percent by weight. Two runs were carried out at each flow rate, and two flow rates were used at each reaction. Reaction temperatures ranged from 225 to 575 C. 

Prepare two tanks and one strip 3 cm wide of each paper as described for experiment 1. Apply 10 pi of the test solution as a streak there is no need to dry the spot. Put the paper in the tank and start the run immediately. For comparison, run a strip in a third gas jar using No. 1 paper, and the solvent used in experiment 1. Allow a run of 10-15 cm, and then remove the sheets, dry and apply the locating reagent. 

Starting the run with a precipitated, reduced, alkalized iron catalyst, this is initially not active (Fig. 11). FT-activity is developed through formation of iron carbide and enrichment of alkali on the surface (Figs. 12,13,14). It reaches the steady state when all the metallic iron has reacted (Figs. 12, 13), and no metallic iron can be any more detected. It follows, metallic iron is not needed for FT-synthesis and also then not present for olefin reactions and CO-medianation (in contrast to FT-synthesis on Co-, Ni- and Ru-catalysts). 

Obtain your unknown licpiid from your instructor. Pour 2 mL of your unknown liquid into the delivery tube above the stopcock. CAUTION Do not inhale the vapor. Open the Teflon stopcock slowly, and allow some of the liquid to enter the flask. The liquid enters the flask very rapidly make certain that vou close the stopcock while there is still about 0.5 mL of licfuid remaining in the delivery tube above the stopcock. If any air also enters the flask at this point, you must start the run again ... 

Formula. In accord with the above description every nonextremal extreme single coronoid (X) corresponds to an extremal single coronoid, A( ), for which A(hr-l) -i A(h) is accompanied by An = 2. The formulas of these special A coronoids are obtained from eqn. (57), but starting the running index from h = 1 i.e. h = 1, 2, 3, 4,...These A coronoids are associated with the... 

At the start of the test, the upstream remote on-off valve was opened and all recorders and photographic recording devices started. The run was allowed to continue until steady-state conditions existed in the transfer line. 

Run gels in 1.8 liters of 0.5x TBE using the following parameters for the CHEF apparatus from CBS Scientific buffer temperature 12 C, 180 V, approximately 170 mA, pulse conditions set to match the size range to be separated. Start the run.
