摘要： PROBLEM TO BE SOLVED: To realize the simplification of an apparatus and its compaction into a small size and to thereby realize remarkable cost reduction and the facilitation of maintenance and enhancement in productivity and economical profitability. SOLUTION: There is provided an apparatus for converting waste plastics into an oil by pyrolyzing them by heating, wherein the body 3 having a hopper which passes waste plastics and a plurality of stages of vertical heating tubes 4a, 4b, and 4c communicating with each other in the body 3 and contained in the body 3 are provided, the upper heating tube is connected to a hot air generator 21, and the lower heating tube is in contact with a chimney 22 communicating with the outside of the body 3, whereby the body is provided with the upper pyrolysis zone and the lower dissolution zone. Thus, it is possible to realize at one time the dissolution of waste plastics P and the pyrolysis of them in the body 3.

摘要： PURPOSE: To fractionate and recover a metal sulfate in the form of pure solid, with simple procedure and low energy consumption, by adding a lower alcohol to an aqueous solution of a metal sulfate, stirring the mixture, and leaving at rest at room temperature or under cooling.
CONSTITUTION: A lower alcohol is added to an aqueous solution to a metal sulfate at a constant temperature or during the cooling proecess from a high temperature to a low temperature. The amount of the alcohol is selected to be sufficient to separate the solid phase of pure sulfate or the phase of concentrated sulfate solution by stirring the mixture and leaving the product at rest. The objective pure solid sulfate is recovered from the obtained solid phase or the concentrated sulfate solution. When the aqueous solution contains plural kinds of metal sulfates, the fractional recovery is carried out selectively and successively from the easily separable salt taking into account the temperature, concentration, the kind of alcohol, etc.

摘要： A process for the treatment of raw materials which contain arsenic and metal to produce a metal-free arsenic product and an arsenic-free metal sulfate is disclosed, in which the raw material is leached by using an aqueous solution of sulfuric acid and then the metals are crystallized as sulfates from the separated aqueous solution, which is separated from the metal sulfate crystals. The leach is performed at elevated temperature under oxidizing conditions, in order to bring the arsenic to a 5-valent form, the metal sulfates are crystallized out from the selectively separated, arsenate-bearing aqueous solution by cooling, and arsenic is removed from at least part of this aqueous solution before the aqueous solution is returned to the leach.
