Abstract: A manganese compound exerting a higher environmental pollutant removal performance than that of a conventional manganese oxide is provided. The manganese compound is obtained by mixing and reacting a bivalent manganese salt aqueous solution and a permanganate alkaline aqueous solution containing a quantity of an alkali larger than a stoichiometric quantity. When comparing the manganese compound with an already-known manganese oxide, it is determined that a specific surface area has significantly increased, and the environment pollutant removal performance is significantly improved. The manganese compound according to the present invention has a high specific surface area value and a high environment pollutant removal performance, and is useful in the adsorption and oxidation-removal of the odor components discharged from factories, NOx, SOx, VOC, and the unburned components such as hydrocarbons, aldehydes and the like which are generated by incomplete combustion.

Abstract: The invention has an object to provide a solid chloride absorbent which can efficiently absorb inorganic chlorides such as hydrogen chloride flowing out from a process in which a heavy naphtha and the like are treated and inorganic chloride derived from crude oil, and which is difficult to powder and soften after absorbing the chlorides. The solid chloride absorbent according to the invention comprises zinc oxide, a porous refractory inorganic matter and an inert binder, has a long life, and hardly releases the absorbed chlorides.

The raw material, reagent and solvent supply unit includes a plurality of reservoirs for containing raw material, reagents and solvents; volumetric tubes and gas-liquid boundary sensors for the quantification of the raw material, reagents and solvents from the reservoirs; flow-lines for supplying the raw material, reagent and solvent from the reservoirs towards subsequent steps; and solenoid valve assemblies disposed on the respective flow-lines for selectively closing and opening such respective flow-lines.

Abstract: A computerized compound synthesization for producing an aimed product by controlling a synthesis reaction process including steps of supplying raw material compounds, reagents and solvents, a synthesis reaction step, a purification step and a product extraction step in accordance with a control program. Optimal condition for the reaction is established by determining discrete time points at which the reagent is added and volumes of the reagent to be added at the time points, respectively, on the basis of parameters including reaction rate constant, equilibrium, constant, initial concentration of starting material mixture, ratio of concentration of intermediate product to theoretical equilibrium concentration, stoichiometrical ratio between the reagent and the intermediate and concentration of the reagent in accordance with a relation established among these parameters.
