Sim Dist

Equipment Use a Hewlett-Packard 5890 Series II GC equipped with a flame-ionization detector (FID), a pressure-programmable on-column injector, an HP 7673 auto-sampler, and an HP Series II integrator, or equivalent. A Chrompack SIM-DIST CB fused-silica GC column (Chrompack Inc., Raritan, NJ) with a 5-m x 0.32-mm id and a 0.1- xm film thickness, or equivalent. A deactivated fused-silica precolumn (0.5-m x 0.53-mm id) coupled to the analytical column via a butt connector (Quadrex Corp., New Haven, CT), or equivalent. 

Cracking properties of a Si-VPl-5 (Si/Al=0.4 in the gel) and the reference catalyst were also investigated by Micro Activity Tests (MAT), using a short contact time MAT (SCT-MAT) which is a modified version of the ASTM MAT with better correlation to a commercial unit 1 g of atmospheric residue was fed to the reactor during 30 seconds at 524°C. Liquid products were collected at 0°C and analyzed on a HP 5880 Sim Dist GC, while gas products were collected over a saturated KCl-solution and injected on a HP 5880 Refinery Gas Analyzer.

P(Dist(ZKPp in)) = 0) - P(Dist(Sim(par, K, auxy i )) = 0)1 is small on average. (Here, the first probability is taken over the random choices of P, V, and Dist, and the second one over those of Sim and Dist.) This means that...
