“…In a well mixed slurry reactor, the gas and liquid phase concentrations o,f gaseous species are in equilibrium, and are related as 4 P j = xjyjfl'. Henry's Law behavior in typical slurry liquids for the principal products and reactants of the FT synthesis (CO, C02, HZ, H2O) has been reported in the literature (e.g., Peter and Weinert, 1955;Huang, et al, 1988). For these species, the standard state fugacity based on Henry's Law can be used, and y j -1.…”

The kinetics of the Fischer‐Tropsch (FT) and water‐gas shift (WGS) reactions were studied in a stirred tank slurry reactor, using a 100 Fe/0.3 Cu/0.2 K catalyst and a commercial catalyst, Ruhrchemie LP 33/81. The 100 Fe/0.3 Cu/0.2 K catalyst was more active than the Ruhrchemie catalyst for both reactions. FT kinetics which accounted for water inhibition was the best of the rate forms considered for the 100 Fe/0.3 Cu/0.2 K catalyst. First order in H2 kinetics was sufficient for the Ruhrchemie catalyst, probably due to the low conversions obtained during the test of this catalyst. WGS kinetics, which included product inhibition, were also studied for each catalyst.

“…They were obtained from a set of five different heavy hydrocarbons. Lattice-gas errors from Table 4 are large in some cases, and are greater than those reported by Huang et al [21]. However, it must be emphasized that the only information needed for lattice-gas model calculations was the molecular weight of the wax.…”

A flow apparatus was developed to determine phase equilibria at elevated temperatures and pressures. The key component of the apparatus is a high-pressure view cell equipped with transparent sapphire windows for visual observation of the liquid level. The flow apparatus is used to the best advantage when the residence time of chemicals (or bic-materials) in the high-temperature zone has to be minimized to eliminate the possibility of thermal decomposition or polymerization reactions. Because the technique has the advantages of rapid attainment of equilibrium conditions and straightforward sampling procedures, it produces a fairly large quantity of data with a minimum amount of time. The sample system also offers the option of taking a desired size of sample by controlling the length of sampling time. This is important particularly for the asymmetric mixtures of a light gas in a very heavy compound of low volatility at some extreme conditions, for which a sufficiently large amount of samples are needed to determine the phase compositions with reasonable accuracy. The flow apparatus of different designs have been used for measurements of vapor-liquid and liquid-liquid equilibria for years. However, it is difficult for multiphase mixtures, and the liquid feed pump cannot handle solids of high-melting points.In operation of a flow apparatus, the liquid level in the equilibrium cell must be sensed and controlled at a certain range of elevation. Simnick et al. (1977) designed a blind cell in which an electric capacitor was installed to detect the liquid level. A similar cell was later fabricated by Inomata and coworkers (1986). However, the capacitor fails to function properly for the mixtures which are electrically conductive (Lin et al., 1985(Lin et al., , 1986. Lin and coworkers (1985) developed a visual cell in which a transparent sapphire window was equipped at each end of the cell body to permit observation of liquid level. A modification of this cell with a new design to improve its sealing of the sapphire windows for operation at higher pressures is Corrapondcna concerning thic pper ahould be addrtsscd to H. hi. Lin.
