ジャーナル フリーAuthor described the trend of metallurgical coke refering to the tendency of iron and steel industries, the problem of coking coals, the quality of metallurgical coke, and the present and future coke production methods, and added his opinions. On the above subjects, the problems on the metallurgical coke that should be researched and considered in future, are explained, final remarks are as follows.
(1) The iron and steel products in japan are not considered to increase rapidly in near future. On the other hand, the problem of lowering caking property (fluidity) of coal and increasing of inert matter of coal will be considered, moreover blast furnace will be changed to larger scale. Consequently coke quality will be required higher, and it should be required to discuss and resolve this problem.
(2) On the other hand, there are many problenms to be resolved in the techiques of coke production, they are rationalization of eqiupments, saving manpower, saving energy, antipollution system, automation and effective utilization of coals etc.
(3) In any case, it will be future important problem that how to decrease the coke production cost by means of establishment of techiniques should be considered.
(4) Summarizing the future problems on the metallurgical coke, as to the pollution problem, the closed system of waste water and Larger scale equipment of removing nitrogen oxide in waste gas should be developed, and as to the plant problem, automation, saving man power and effective usage of not utilize raw materials are required, and establisment of formed coke process is also desired.
The anthor considers that all the engineers and researchers in Japan should cooperate and make efforts to resolve problems written above.抄録全体を表示PDF形式でダウンロード (2438K) -

ジャーナル フリーIt is after the fourth middle war when there arose fnergy saving tendency in Japan. The Japanese government started new project called “Sun-Shine” in search for new energy source, and announced several policies for heat recovery in industrial field, and they also decided target of fnergy saving in Japan at the time of 1985, that is, 9.4 % by rate and 70, 000, 000 kl/yr at actual value.
In response to the above mentioned new policy, various hinds of apparatuses are actively developed for heat recovery. We, hercunder, introduce examples of actual usage in Japan of “Iso Thermo Coil”, which is apparatus for industrial heat recovery, developed by FRDA, U. S. A. This apparatus with heat pipe was already used for controlling heat f lance of satellite.抄録全体を表示PDF形式でダウンロード (868K) -

ジャーナル フリーThis report describes the results of char production with a midget plant which has a reactor with diameter of 350mm and volume of 70 liter.
The optimum pretreatment conditions of asphalt were as follows; pretreatment reagent (60%-oleum): 1. 5 times of asphalt by weight, solvent (1, 1, 2-trichloroethane): 10 times of asphalt by weight, dropping period of pretreament reagent: 20 min, reaction period: 60 min, reaction temperature: 100°C and stirring rate: 200 r. p.m.
The char, its bulk density being ca. 0.65 g/ml, was obtained with yield of 120-30 wt % under these coditions. And ca. 75 wt % of char obtained was granulated char which sieved into 4-32 mesh range.
When char was activated by steam at 850°C for 30 min, the activated carbon, which has specific surface area of 1000-1300 m2/g and methylene blue adsorbability of 230-300 mg/g, was obtained with yield of ca. 30 wt % based on asphalt.Also, both the char production, using the midget plant, from asphalt and powdered char sieved under 32 mesh as raw materials, and the char production by sulfuric anhydride as pretreatment reagent reproduced the results of laboratory-acale experiment well.抄録全体を表示PDF形式でダウンロード (826K) -

ジャーナル フリーThis report describes the results of activation of char produced with a midget plant.
Char, which was carbonaceous material prior to activation, was carbonized continuously at 450°C with a 105mm∅-fluidized-bed reactor and this carbonized char was activated at 800-900°C with the other105mm∅-fluidized-bed reactor by batchwise method. The yield of the carbonized char was ca. 72.0wt%.
The activation reaction was considerably influenced by the scale of reactor; the nominal rate of the activation reaction became slower than that of the laboratory-scale experiment. And the lower the activation temperature was, the more remarkable the nominal rate of the activation reaction was influenced by the scale of reactor.
When char was activated with steam at 900°C for 60min, activated carbon which had a specific surface area of 1200m2/g and methylene blue adsorbability of 250mg/was obtained with yield of ca. 30wt% based on asphalt.
If the height of layer of char was lower than 3 times to the diameter of reactor, the yield of the activated carbon was not influenced very much by the height of layer of char in case of activation by this midget plant. And the lower the height of layer of char was, the better the properties of the activated carbon were in case of the activation temperature of 800 and 850°C, while these were not influenced very much by the height of layer of char in case of the activation at 900°C.
It was investigated whether the yield, specific surface area and methylene blue adsorbability of activated carbon could be estimated based on activation temperature and period, and some regression lines were obtained as one of the statistical estimation method.抄録全体を表示PDF形式でダウンロード (629K) -

ジャーナル フリーThe physical properties and catalytic activities of vanadium oxide-alumina catalysis prepared by precipitation methods were studied. A highly active catalyst was obtained by mixing alumina hydrogel, prepared by hydrolyzing sodium aluminate with nitric acid, with a chloride free vanadium compound (such as ammonium meta vanadate, vanadil oxalate and sodium vanadate) in wet state. Calcination at temperatures above 700°C was found essetial to the high activity. Percents NO removal at standard reaction condition (SV 20, 000hr-1, NO 300ppm, NH3 450ppm, SO2 100PPm, O2 5%, H2O 10%, N2 balance) were as follows: 70.0% (200°C), 99.2% (250°C), 99.2% (300°C), 99.8% (350°C). The way of preparing the alumina hydrogel had a marked effect on its pore structure but little effect on the catalytic activity.抄録全体を表示PDF形式でダウンロード (806K)
