ジャーナル フリーThis process is a new process which has been developed for the purpose of producing light oil, as well as useful carbon materials by thermally cracking in liquid phase petroleum heavy ends, such as straight asphalt.
Coking trouble was overcome by adding a appropriate amount of coal powder to the feedstocks, so that the process could be designed in a full continuous flow.
As a result of a throughput 36t/d test plant work to obtain various data required for scaling up to a commercial plant,
(I) various kinds of information regarding to continuous operation and designing work was obtained, and
(II) it was comfirmed that the process was characteristic of yields and properties of the products.
It was found that the heavy products were useful for producing coke as a heavy coking coal substitute and binder for briquettizing.
Furthermore, the applicability of the process produce light oil from paraffinerich heavy ends of Chinese petroleum was pointed out.抄録全体を表示PDF形式でダウンロード (1296K) -

ジャーナル フリーFor iron and steel industry in Japan, past five years were hard times, the sccalled “Energy crisis” and the following dipression drove this industry into retionalization of production.
The energy conservation is of vital importance to us. Now, we had luke to these techniques are fixing in the rationalization by degnees, at our iron and steel works. This paper reports the energy consumption and some example of energy conservation techniques at various areas of iron steel industry in Japan, particularly of integrate workes.抄録全体を表示PDF形式でダウンロード (1148K) -

ジャーナル フリーEffects of various reaction conditions on reaction rate and mechanism of coal liquefaction were investigated. Conclusions were summarized as follows:
(1) The order of the reaction, reaction rate, oil yield and composition were affected by kinds of pasting oil and ratio of coal to pasting oil.
(2) Under the same reaction conditions, reaction rate and mechanism of coal liquefaction differs from kinds of coal and catalyst. The reaction rate was in the order: Morwell>Bukit Asam>Miike>Taiheiyol≅Hikishima. Kinetic scheme of coal liquefaction was expressed as follows:
for Morwell and Bukit Asam coals,
Coal (1) k1→Asphaltene k2→Oil1 (2) k3→Oil2 k1<<k2<k3 (at<380°C) (1) >> (2)or Coal (1) k1→Oil1 (2) k3 →Oil2 k1<<k3 (at>380°C) (1) > (2) and for Miike Taiheiyo and Hikishima coals, Coal k1→Asphaltene k2→Oil k3→Resin k4→Coke k3<k4<k1<k2, or k3k4<k2<k1 The magnitude of the rate constants k1 and k2 is different from kinds of catalyst.
(3) Activities of catalysts were as follows; H2MoO4·H2O>Fe (OH) 3-MoO3-S>MoOs>Fe (OH) 3-S. The activity of Fe (OH) 3-MoO3-S catalyst may be due to the concerted action with MoO3 and Fe (OH) 3-S, and degrees of resinification and coking were dependent on kinds of catalyst.
(4) In making a kinetic analysis of the experimental data with autoclave, a nonlinear least square method was used to estimate the parameters in the Arrhenius equation under nonisothermal conditions. The theoretical values of componet, caluculated by substituing the estimated values into the rate equations, were in good agreement with experimental values.抄録全体を表示PDF形式でダウンロード (1325K) -

ジャーナル フリーOperational factars affecting the reduction of nitric oxide by ammonia over silica supported vanadium oxide catalysts were studied. Small amount of oxygen in the gas phase enhanced greatly the reaction rate as is the case on alumina supported vanadium oxide catalysts. Reaction rate was expressed by the equation: r=kP0.65NOP0.14NH3P0.28O2 at the following conditions: 200°C, NO 200-800ppm, NH3 200-600ppm, O2 1-20 vol %. Sulfur dioxide and steam showed little adverse effects on NO removal 98% conversion of NO at 250°C under the following conditions: NH3/NO1.5 (mol ratio), space velocity=20, 000cc/g-cat·hr and in the presence of sulfur dioxide and steam. Life test of the catalyst at 230°C using a combustion gas containing 660ppm of sulfur dioxide was carried out. The initial NO conversion was 94% and a steady state conversion of 84% was attained after 50hr and lasted for 200hr. The accumulation of ammonium hydrogensulfate on the catalyst was quite small compared to that on the alumina supported catalyst. A dynamic equilibrium between the formation and evaporation of ammonium hydrogensulfate.抄録全体を表示PDF形式でダウンロード (563K) -

ジャーナル フリーProton FID signals were measured for 9 kinds of coals (<200 Tyler mesh) using a 20MHz pulsed NMR spectrometer, and it was found that some signals consisted of several components which had different T2 values. The percentage of protons having the longer T2 value (T2l) agrees well with that obtained by the usual drying method, and the T2l fraction vanished when heated at 110°C for 2 hrs. Therefore, the fraction may be attributable to H2O protons. The percentage of H2O protons obtained by the pulsed NMR method appears to be be larger than that obtained by the drying method.抄録全体を表示PDF形式でダウンロード (822K)
