The gasification studies on the selected cellulosic wastes (Saw dust, Coir dust, Copra meal and Cassava bagasse) by fluidized bed method were investigated to determine the ideal conditions and variables suitable for generating power.<BR>Experimental runs on the steam and air gasification were carried out using bench scale gasification apparatus.<BR>The results on the steam gasification showed that at varying bed temperature ranging from 750 to 900°C, gas product with high H2 and CO content (more than 70%) having high heating value (2, 500-3, 700 kcal) were obtained.<BR>The ranges of heating values of the produced gas obtained from air gasification at appropriate operating condition were 1, 000-1, 350 kcal for saw dust, 1, 170-1, 300Kcal for coir dust, 1, 200-1, 700Kcal for cassava bagasse, and 1, 350-4, 800 kcal for copra meal.<BR>Preliminary test run of the gas engine was done by charging LPG mixed with air to determine the minimum practical heating value for smooth operation. Results of the test run showed that 1, 200 kcal was minimum heating value with gas pressure of about 1, 200 mmH2O to maintain the smooth operation.<BR>Based on the data from the preliminary test, the gas fuel products generated from saw dust were tested on the gas engine.<BR>Results showed that low calorie gas products with heating value as low as 1, 300 kcal can be utilized to run a gas engine for generation of electric power.

In this paper it was introduced to peacefully utilize underground atomic nuclear explosions which had been started in New Mexico, 1967. Now, the five projects have been developed in U. S. A. However, those projections are highly speculative and open to serious questions for practice.<BR>World Oil informed to discuss the such speculations and questions.<BR>Journal of Petroleum and Quarterly of Colorado School of Mines had reported about recovering oil from nuclear chimney retort and current Coal Age published a Thunderbird Project which was a nuclear trigger for coal gasification.

第2報, 第3報においてZn-Cr-Mo-K2CO3系触媒が良好なことがわかつたので, 第4報において, 反応温度, 反応圧力, 空間速度, 原料ガス組成の影響を求めた。その結果, 反応温度は, 400~450℃の範囲が適当で反応温度の上昇と共に, ガス消費率 (CO/H2) は漸次増加しCO2, CnHm, CH4の生成量は増加した。反応圧力についてはイソブタノール収率には顕著な影響はあらわれなかつたが, 生成液量は圧力とともに増加した。200気圧以下では生成水増加の傾向がみられた。空間速度についてはイソブタノール収率のみ考えれば6, 000が適当であり, イソブタノール収量の点からいえば反応温度450℃, 空間速度15, 000が適当と考えられた。原料ガスの組成については,.CO: H2=1: 1の附近が最も高級アルコールの生成が大であり, メタノール, 水の生成は少かつた。しかしCOの多いほど, CH4, CO2, CnHmの生成は増加した。

To recover fuel oil from oily sludge, experimental studies were performed using a fluidized sand bed pyrolyzer. The heat energy for the pyrolysis of sludge was supplied from the heat of a partial combustion of sludge. It was revealed that the yield of recovered oil decreased with increasing bed temperature within the range of from 500 to 600°C. The viscosity of recovered oil decreased with the increase of the oxygen concentration in fluidized gas. The properties of the recovered oil ranked with those of the fuel oil. Moreover, the sulfur content in recovered oil was reduced to 70%, as compared with that in sludge. When lime-Stone or natural zeolite were used as the fluidized particles, relatively low viscous oil could be produced, but its yield value was small compared with the use of silica sand. The estimated value of heat con-sumption for pyrolysis was ranged from 390 to 530 kcal/kg.

It seems that the synthesis of natural gas into synthetic petroleum is not taken into consideration yet though the conversion of natural gas into liquefied natural gas or methanol has been done as the means of its transportation. The author has examined the synthetic petroleum from natural gas.The present status of South African Coal, Oil and Gas Corporation (SASOL), only one operator of Fischer-Tropsch synthesis in the world, is reported here after the explanation of Fischer-Tropsch synthesis.Then it is proposed that the synthetic petroleum will be supplied to the consuming country after the Fischer-Tropsch synthesis with the reforming of natural gas into CO and H2, and it is indicated that the synthetic petroleum with the technique of SASOL can be competitive with LNG, methanol and crude oil in economic view point.

In Japan, combustion modification and SCR process are widely applied for NO control in thermal power plants. By combustion modification, 50-70% of NOx can be reduced to 40-60 ppm for gas-fired, 80-120ppm for oil-fired and 150-200ppm for coal-fired boilers. Recently, in-furnace NOx reduction techniques such as IFR, three-stage combustion are also developed. When further NOx reduction is needed, flue gas treatment technologies such as SCR should be used. Simultaneous SO2 and NOx control processes using activated char or electron beam being developed for cost reduction. NOx control technologies may become more important in many countries to solve acid rain problem.

The study of slurry phase Fischer-Tropsch synthesis which is operated by introducing synthesis gas into the suspension of fine powdery catalyst in heavy oil was begun in Germany during World War II. After the war, investigations were coducted in West Germany, in England, in the United States and in Japan to prove the excellence of the process.The slurry process which utilizes precipitated iron catalyst is characterized by the flexibility with which it can process CO rich gas with CO/H2 ratio up to 0.9 to give naphtha, middle distillates or heavy oils as the major products. The change in product pattern is achieved by only regulating catalyst composition and reaction temperature. The processing of CO rich gas in the slurry reactor is not only suitable for utilizing the product gas from the second generation coal gasifiers but also favorable for highly efficient F-T process. It is pointed out that the slurry process should be aimed at diesel fuel production because of the chemical character of products. The low productivity of slurry reactor is expected to be overcome by adopting some new technologies.

Photosystems of plants or photosynthetic microorganisms have a function to split water molecules to produce electrons. This paper describes a trial to draw photosynthetically generated electrons out from the microorganisms to produce electricity by using a electron transfer mediator. Such devices, which we call microbial fuel-cells, enable us to convert light energy to electricity directly. A microbial fuel-cell containing a marine alga and 2-hydroxy-1, 4-naphthoquinone as a mediator has been discussed and the conversion efficiency from light energy to electricity has been estimated from the comparison between output current and the amount of oxygen evolved.
