摘要： PROBLEM TO BE SOLVED: To provide a method for converting waste plastics into a fuel by thermal cracking, effective for preventing the clogging of a treating apparatus by the deposition of a crystalline organic material in a volatile component into gas, in a fuel conversion apparatus and enabling stable continuous operation. SOLUTION: Waste plastics are converted into a fuel by thermal cracking. The volatile component containing the crystalline organic material and generated by the thermal cracking is supplied to a 1st jet scrubber, sucked and mixed into a circulating oil at a temperature lower than the sublimation point of the crystalline organic material to cause the abrupt cooling and the deposition of the crystalline organic material and, at the same time, to condense an organic component (component A) having a boiling point higher than the circulating oil temperature to form the fuel, and the product is separated into the crystalline organic material, the liquefied organic component A and gas.

摘要： PROBLEM TO BE SOLVED: To make it possible to suppress liquid resistance without adding a large amt. of electrolyte and to easily produce gaseous hydrogen of a high pressure with high electrolytic efficiency.
SOLUTION: Water is supplied to an anode chamber 16 and cathode chamber 17, respectively, which are partitioned by an insulative diaphragm 14 which is permeable to H
+ ions and OH
- ions but have poor air permeability. An electrolysis is effected by maintaining the water of the anode chamber 16 and the cathode chamber 17 in a subcritical state and superctritical state, respectively. Either or both of the pressure or temp. of the water contg. the gaseous hydrogen in the subcritical state or superctritical state generated in the anode chamber 17 is lowered, by which the gaseous hydrogen of the high pressure is taken out.
