configuring the unit
(P) High pressure: This option adds a pressure control loop to the basic unit; it enables working up to 100 bar with an accuracy of 0.1bar. Pressure control is based on a servo motorized micrometric regulation valve (WO-2006021603 / EP-1775504 / US-2007241296) that gives it maximum stability in pressure control thus minimizing the piston flow pulse effect of the stream that flows across the catalyst bed. This system, developed especially for the Microactivity-Reference, deliver excellent reproducibility in experimental data.
(G) Liquid Feed: This option enables a liquid feed via an HPLC pump, for working in either the liquid or steam phase, and operating at pressures of up to 100 bar. The pump is installed with the necessary accessories to ensure a continuous flow that is precise and without pulse, even when the feed is to be evaporated.
(L1) High pressure liquid-gas separator: A microvolume system for liquid-gas separation at a reactor's outflow that operates at high pressure (WO-2006021604 / EP-1757911 / US-2007238753) is perhaps the Microactivity-Reference main contribution to quick evolution and development in experimentation in the field of catalysis. With a dead volume less than 0.5 ml, this system enables real time separation of condensables, thus making it possible to learn the composition of the liquid products obtained during the first reaction minutes. This makes it possible to study reaction kinetics and catalyst deactivation since the condensate during reaction is representative of the last few minutes.
(L2) High pressure liquid-liquid-gas separator: This is the latest evolution with which PID Eng&Tech contributes the advance in catalytic reaction control. This configuration option is an evolution of the aforementioned liquid-gas separating system. It enables separation of two non-miscible liquid fractions, e.g. for use in Fischer-Tropsch reactions (GTL) (Patent P200930603– PCT/ES2010/070559 - WO2011/020939 - EP2469246). The high-pressure separator has no appreciable dead volume and produces three differentiated phases in real time: the condensable hydrocarbon, water and the gaseous fraction with lighter hydrocarbons.
