JOURNAL FREE ACCESSOn the one hand, now the buyer's market in going to finish and the era of potential over-supply and low prices may gradually pass away.
On the other hand, the growth in energy demand is accelerating through the world.
In the background like this, Japan must seek for huge energy that will reach one billion k/ of oil equivalent in 1985.
Because of energy's security, now decisive policies need.
a) Exact recognition of the energy resources.
b) Co-ordination between energy and energy, and of countries each other.
c) Look over again of energy sources (specially coals ond ocean energy)
d) The mutual relation energies and a elasticity to energy.
e) Downstream in the producing countries of energy resources.
f) Arrangements of used energy and Co-ordinations of new energy's utilization between energies.
g) A institution of a strong organization for our energy
Under these strong policies, we would expect developments of new projects to take the initiative.
a) Manufacture of reduced iron at contries with resources.
b) Hydrogenation of coal to produce synthetic petrol and gasification of offset natural gas.
c) Collecting uranium from sea water and utilization of ocean energy,
d) Establishnent of combinates for uses of numerous purposes of atomic energy (Atomic iron, Gastification and Electric generation, etc.)
e) Promotion of technology of thermal efficiency-up (M. It D. generator, fuel battery)
f) Establishment of overall energy stations for stockpile and development.
g) Mutual utilization of energy installations (pipe lines etc.)View full abstractDownload PDF (1814K) -

JOURNAL FREE ACCESSThe microbiolgical treatment of industrial wastes are now common practice
In many cases, it provides a very ecomomical means of rendering toxic substances suitable for discharge into sewers and natural surface waters.
There are natural oxygen-replenishing processes named self-purification, which/endow surface waters with a certain ability to overcome the polluting effects inflowing waters.
However, in spite of adequate treatments of materials discharged from factories and works should all soon face to severe pollution problems.
In general, mixed cultures containing many types of microorganisms are employed in the purification of industrial wastes, although in certain instances microorganisms with special resistance or metabolic activities are required.
The present review has summarized the microbial treatments of industrial wastes, and described in some detail on microflora of activated sludges.View full abstractDownload PDF (1690K) -

JOURNAL FREE ACCESSWater contamination in generally divided into two kinds, excremental Contamination and one caused by toxious substances. From these contamination, mass infections diseases and toxications are likely to break out.
In order to control aud water pollution, we now have “Basic Law. for Environmental Pollution Control” “Water Pollution Control Law”, which regulate standards of environment and water quality. Both standards limit allowable quantity by ingredient, and we must recognize their sanitary importance.
The general problem sewage disposal can be solved by improvement of coagulants, treatment of actived carbons, sludge treatment, and other procedures.View full abstractDownload PDF (1274K) -

JOURNAL FREE ACCESSThe bituminous coal extracted with pyridine was sulfonated with 97% sulfuric acid or dioxane-sulfurtrioxide complex.
In case of the sulfonation of coal with conc. sulfuric acid (coal 1g: H2SO4 10cc.) suitable reaction temperature was 60°C and reaction time was required more than 2 hours.
The sulfonation and appreciable oxidation of coal with sulfonating reagents were taken place at the same time, and the oxidation was more prominent at the higher reac-tion temperature with the increase of carboxyl group and the decrease of sulfonic acid group.
The structure unit of coal was calculated to be 330-430 from sulfonic acid equiva-lent of sulfonated coal, and this derived value was consistent with the value in many papers.View full abstractDownload PDF (1188K) -

JOURNAL FREE ACCESSNew pipeline charging system of preheated coking to coke ovens was developed by Allied Chemical Corporation.
This system increases oven production by reducing coking time.
The process also permits the use of lower cost, poorer quality coals to produce acceptable metallurgical grade coke.
It is most remarkable effect of this new system, that the control of air pollution from coke ovens may be significantly improved.View full abstractDownload PDF (1088K) -
