A fluid separation apparatus is described, including a casing and a separation module. The casing includes a mixed fluid inlet, a separated fluid outlet through which a selectively separated fluid is discharged, and a residual fluid outlet. The separation module has a set of serially arranged separation elements disposed therein and is insertable into the casing from an end of the casing. The separation module includes a first connection jig disposed between adjacent separation elements, second connection jigs disposed at two ends of the set of serially arranged separation elements, and a coupling jig coupling the first and the second connection jigs to each other.

A reactor for synthesizing hydrogen sulfide in which sulfur and hydrogen are subjected to gas-phase reaction in the absence of a catalyst to synthesize hydrogen sulfide, the reactor including: a reactor body that retains liquid sulfur in a bottom portion thereof; a heating unit that gasifies part of the liquid sulfur; a hydrogen gas supply unit that supplies hydrogen gas into the liquid sulfur; and a heat-exchanging portion provided in a gas-phase reaction region located above the liquid surface of the liquid sulfur in the reactor body, wherein heat-exchanging portion is configured such that the reaction temperature in the gas-phase reaction region is controlled to be within a predetermined temperature range by changing the heat exchange amount per unit volume in a gas-phase reaction region located farther from the liquid surface from the heat exchange amount per unit volume in a gas-phase reaction region located closer to the liquid surface.

The present invention relates to a novel catalyst having a stable catalytic activity for catalyzing the reaction of an alcohol with carbon monoxide and oxygen to produce carbonic acid esters (i.e., carbonate), and also the present invention relates to a method of producing carbonic acid esters using this catalyst. The catalyst of the present invention comprises a copper halide and at least one hydroxide compound selected from a group consisting of alkali metal hydroxides and alkali earth metal hydroxides carried on a porous carrier, and also provide a process of regenerating a catalytic activity of the catalyst.

The present invention relates to a process for the manufacture of hydrogen sulfide by reacting sulfur and hydrogen which comprises two hydrogenation reactions. The first hydrogenation reaction of the present invention comprises the steps of supplying hydrogen gas in a reactor containing sulfur at least a part of which is in a liquid phase at a temperature of not lower than 250.degree. C., and reacting the liquid sulfur and the hydrogen gas to produce a crude hydrogen sulfide effluent gas in the reactor. The sulfur vapor contained in the effluent gas is further reacted with fleshly added hydrogen gas in the second hydrogenation reaction to further concentrate the resulting hydrogen sulfide.
