    Abstract: An analysis process is provided for the determination of a complete material balance of a chemical reaction, especially useful in the studies of catalyst activity. A complete material balance is obtained by determining the output flow from a reactor at the temperature and pressure conditions of the chemical reaction. The reactor output flow is determined by first analyzing the effluent volume composition at the temperature and pressure conditions of the reaction. Subsequently, the effluent is expanded and the volume composition and flow rate of the expanded effluent are measured. From these measurements and the volume composition at the reactor output, the output flow from the reactor is determined. A strict material balance is then possible by comparing the input flow rate and volume composition to the output volume composition and flow rate, thereby establishing a complete material balance at the reaction temperature and pressure. The process is suitable for testing the catalytic activity of even small amounts of catalysts independent on the catalyst shape. Moreover, the process provides a high degree of reproducibility through the automation of temperature control and the analysis of volume compositions and flow rates.

    Abstract: For measuring the adsorption and desorption of a gas adsorbed by a solid sample, a gas pressure drop during the adsorption phase or a gas pressure increase during the desorption phase is programmed in the reservoir circuit 1 from 0.1 to 0.7 Pa per minute by at least one regulating valve V.sub.P1 having a proportional opening, in order to transfer a substantially constant flow of gas to the sample and from the sample to the reservoir, the gas pressure being measured periodically in the measuring circuit by pressure sensors. By a microprocessor, the isotherm of adsorption and desorption is determined based on the volume of the reservoir circuit, the quantity of gas transferred, the gas pressure in the measuring circuit, and the volume of the measuring circuit. The system measures the adsorption-desorption isotherms of a gas from a solid.
