ジャーナル フリーSince 1960, many tests were repeated to make hot-briquettes from domestic coal. As a result of the tests, special middle scale plant (capacity: 170kg/hr), using a rotary kiln, has been completed. Using this plant, manufacture of hot-briquettes was made with success.
The raw material was a mixture of 71-74% of non-caking coal and 29-26% of caking coal. When we used it, the raw material was first crashed to less than 30 mesh, and then heated for 30 minutes in a rotary kiln (the temperature of the materialwas normal near the inlet of a rotary kiln and about 380°C near the outlet) and briquettedunder nearlyoutlet temperature by a double roller press (φ360mm×140mm, no of mold 26×4).
The result of this test was as follows.Compression strength >90kg.Trommel index >90.Compression strength at 800°C >200kg.
It might be concluded that this hot-briquette will be able to be used for smokeless fuel, iron manufacture, etc.抄録全体を表示PDF形式でダウンロード (1294K) -

ジャーナル フリーMuch sample of uniformly heat-treated coal was prepared by using a nitrate bath in which the vessel containing a thin layer of coal sample was heated. The Japanese Nishikawachi strongly coking coal was added to the sixteen vitrain samples described in previous paper. These samples were heat treated with a heating rate of 3°C/ min. over the range from heat treatment temperature (HTT) 200°C to 500°C at intervals of 50°C.
The yield of products the state of devolatilization have a strong correlation with the chemical constitution of original coals. Therefore, the yield of products at HTT 500°C is analogized from the proximate and ultimate analytical constitution of original coals.
The analytical constitution of heat-treated coals depends on HTT and coal rank.
In general, the beginning temperature of change in heat treatment increases with the increase of coal rank. The chemical constitution of heat-treated coals hardly changes below HTT about 350°C, except the lower rank coals below about 80% C. It seems, however, that the change of physical structure of heat-treated coals may happen below HTT about 350°C.
At HTT about 400°C, the chemical constitution in coking coals of 83-87%C begins to change and the devolatilization rate of the lower rank coals shows a maximum. For coking coals, the devolatilization becomes violent and the ultimate analytical constitution of heat-treated coals changes largely at HTT about 450°C. At HTT about 500°C, the change of chemical constitution in strongly coking coals of about 90% C becomes remarkable.
The reaction occured by heating up to HTT 500°C is mainly dehydration for lower rank coals. Dehydration and then demethanation predominate with the increase of coal rank.
The aromaticity of heat-treated coals increases suddeny with the increase of HTT. The aromaticity and the chemical constitution of heat-treated coals at HTT 500°C do not show so large difference each other in comparison with the large difierence in original coals.抄録全体を表示PDF形式でダウンロード (1484K) -

ジャーナル フリーCombustion performance of several domestic stoves was tested and smoke emission and heating efficiency were measured. Straight-line relationship was established between optical density and concentration of solids of smoke, whether the fuel was bituminous or sub-bituminous coal. The amount of solids in smoke emitted depends mostly on rank of coal and constructional design of combustion chamber of the stove.
The stove of hand-fired type emitted the most soot, Chotan-stove, for lump coal, and Funtan-stove, for small-sized coal, the less and Lumpen-stove, the least. Bituminous coal fired out soot twice as much as sub-bituminous.
The stove, giving good performance such as of less soot emission, when coal was fired, showed rather worse heating efficiency because of higher temperature of flue-gas. The more smoke emission did not always result the worse thermal efficiency.
Performance of stove will be assessed from its feasibility to maintain steady combustion following up immediate change of various conditions during heating time.抄録全体を表示PDF形式でダウンロード (1343K) -

ジャーナル フリーThe report is some consideration on the fluidized catalytic cracking of petoroleum hydrocarbons.
Catalyst is any non-caking coal such as Lignite, Brown-coal, or sub-bituminous coal, irrespective of its brand.
(1) Fluidize is reply of catalyst in an conical fluidized reactor. consideration on the simple subustance of fluidized catalyst in to reactor. and catalyst of carryover is litter, further catalyst particle size in wide range of about 0.1-18 mm its can be used.
(2) Efficiency of gasification in the teeter-bed and spouted-bed efficiency of gasification in the fluidized catalgtic cracking of naphtha. It is for the teeter-bed 90-93% and spouted-bed 70-75%抄録全体を表示PDF形式でダウンロード (1341K) -

ジャーナル フリーThe first M. S. naphtha reforming plant in Japan was constructed at the gas works Tokorozawa near Tokyo in 1962. In favor of its superiority in construction, operation, and gas quality, it will be accounted more than 40 Sets in all at the end of this year.
The characteristics of the M. S. plant are as follows.
1. Temperature cycle system.
2. Tangential injection of raw materials.
3. The use of catalyst of raschig-ring form.
The heat oil ratio is small than other reformers. The working condition, results and the cost of gas produced are described. About the hot shift CO-converter studied by the author, is also referred to.抄録全体を表示PDF形式でダウンロード (616K) -
