Abstract: A process for the dry distillation of used rubber in a fluidized bed-forming oven comprises heating used rubber under agitation in the presence of solid particles to temperatures sufficient to make the rubber pulverized and further heating the thus-obtained rubber particles to temperatures sufficient to pyrolyze the rubber particles while forming a fluidized bed thereof and burning a part thereof in the stream of an oxygen-containing fluidizing gas.

Abstract: A method of separating carbon dioxide from a carbon dioxide-containing gas is disclosed, wherein the carbon dioxide-containing gas is contacted with a metal oxide to fix the carbon dioxide as a metal carbonate, and the metal carbonate is thermally decomposed into metal oxide by contact with a combustion gas produced by combusting a fuel with a pure oxygen gas. The metal oxide thus produced is recycled to the previous step for fixation of carbon dioxide. A combustion apparatus is constructed to carry out the above method so that the combustion gas produced is treated to separate the carbon dioxide contained therein.

Abstract: A method of separating carbon dioxide from a carbon dioxide-containing gas is disclosed, wherein the carbon dioxide-containing gas is contacted with a metal oxide eg CaO or MgO, to fix the carbon dioxide as a metal carbonate, and the metal carbonate is thermally decomposed into metal oxide by contact with a combustion gas produced by combusting a fuel with a pure oxygen gas. The metal oxide is recycled to the previous step for fixation of carbon dioxide. A combustion apparatus is constructed to carry out the above method so that the combustion gas produced is treated to separate the carbon dioxide contained therein.

Abstract: PURPOSE:To efficiently convert at low cost the peat which is an unused resource into an energy easy to handle, by bringing peat into contact with a hot oil at a particular temp. or above to decrease the water content and, at the same time, to deposit oily matter thereon, followed by gasification or combustion. CONSTITUTION:Peat is brought into contact with a hot oil of 100 deg.C or above (e.g., waste vegetable or animal oil) to conduct a hot oil treatment, thereby decreasing the water content and, at the same time, depositing oily matter thereon. The peat is then separated from the oil. The hot oil-modified peat thus obtd. is gasified or burnt. Thus, the peat which is difficult in itself to use as a fuel can be converted into an energy easy to use. The gasification or burning is advantageously conducted in a fluidized reactor. The gasification is conducted by heat-treating the peat at 700-1,100 deg.C using air or oxygen and steam as the fluidizing gas. On the other hand, the burning is conducted by using air as the fluidizing gas.

Abstract: PURPOSE:To separate CO2 in CO2-containing gas in high device efficiency by bringing the CO2-containing gas into contact with metallic oxide to react and form metallic carbonate and thermally decomposing an obtained metallic carbonate by a combustion heat obtained at the time when a fuel is burned with a pure oxygen to convert the carbonate into the metallic oxide. CONSTITUTION:In a CO2 absorption device 1, the CO2-containing gas is brought into contact with the metallic oxide (e.g. CaO) to allow CO2 incorporated in the gas to react with the metallic oxide and to form the metallic carbonate (e.g. CaCO3). And in a metallic carbonate thermal decomposition furnace 2, the fuel (e.g. fine pulverized coal) is burned with the pure oxygen to thermally decompose the metallic carbonate by the combustion heat obtained at that time. Moreover, the metallic carbonate formed in the device 1 is transferred to the thermal decomposition furnace 2 with a piping 6. Then, the metallic oxide formed at the furnace 2 is transferred to the device 1 with the piping 12. On the other hand, the CO2 formed in the furnace 2 is discharged outside the system through a gas discharge pipe 11. This CO2 is not incorporated with gaseous nitrogen.

Abstract: PURPOSE:To enable an amount of occurrence of N2O and NOx to be concurrently and substantially reduced by a method wherein fluidizing air is supplied to a first combustion region in a fluidized bed part, secondary air is supplied to a second combustion region ranging from a free board front stage to a middle stage and third air is supplied to a third combustion region ranging from the middle stage of the free board to a rear stage. CONSTITUTION:Main fuel is supplied from a supplying port 2 to a first combustion region in a fluidized bed 15 and an amount of air which is approximately equal to a theoretical amount of combustion air with respect to the main fuel or less than that is supplied as fluidizing air. Additional fuel and an amount of air which is approximately equal to a theoretical combustion air amount with respect to the additional fuel or less than that are supplied from a double-stage combustion burner 4 as secondary air. In addition, the main fuel and an amount of air which is requisitely sufficient for a complete combustion of the additional fuel are supplied as the third air 5 to the third combustion region located from the middle stage 16 of the free board to the rear stage 17. With such an arrangement as above, an amount of occurrence of N2O and NOx can be concurrently and substantially reduced.

Abstract: PURPOSE:To make the easy sepn. of the oil-component and solid matter in oil-contg. sludge possible by making use of the partial combustion heat of the sludge. CONSTITUTION:The oil storage tank sludge 5 is brought into contact with an oxygen-contg. gas 4 in the fluidized bed of a fluidized bed type thermal cracking furnace 1 to burn partially the sludge 5; at the same time, the oil- component in the sludge 5 is reformed to a low-viscosity oil by thermal cracking. The reformed oil obtd. in the above-mentioned manner is separated in a vapor form from the upper part of the fluidized bed to the outside of the system. The solid matter contained in the sludge 5 is separated from the lower part of the fluidized bed to the outside of the system. As a result, the easy sepn. of the oil-component and solid matter and further moisture in the sludge is made possible and the recovered oil obtd. in this stage has the low viscosity and permits easy transportation with a pump, etc., even without being mixed with a light oil or heavy oil.
