JOURNAL FREE ACCESSAmong the many papers presented at the 7th World Petroleum Congress in Mexico, the followings seem to me to be interesting.
(1) On the production of isoprene as the raw material of synthetic natual rubber.
Isoprene is now generally produced by the reaction between aluminium tripropyl and propylene, but Dr. Wilkes of Chevron Research Co. proposed the process to use potassium for the dimerisation of propylene.
The dimer obtained is mainly composed of 4-methyl-1-pentene which is then isomerized to 2-methyl-2-pentene, followed by the cracking to produce isoprene.
(2) New oligomer synthesis
Dr. R. Kh. Freidlina of USSR proposed the use of Fe (CO) 5 for the Oligomerisation between CCl4+CH2=CH2, although the ratios of n in CCl3 (CH2-CF2) n Cl did not change in the change of the initiater from peroxides to Fe (CO) 5.
Next, the hydrodimerisation of acrylonitrile to adiponitrile was reported by Dr. M. M. Baizeru of Monsanto Chemical Co.
(3) Oxidation
Dr. F. K. Fields of Amoco Chemical Cor. reported the ozonolysis of olefins in the presence of anionic reagents such as alkali, ammonia and hydroxylamine.
In the presence of ammonia, cyclohexadiene converted to pyridine and similar reactions were observed in the Ozonolysis of cyclic dienes.
The propylene oxide production was corned out by the reaction of hydroperoxide with propylene in the presence of Mo catalyst. Dr. R. Landau of Landau of Halcon International Inc. used the hydroperoxide from ethylbenzene, although various kinds of modified processes are well known, such as acetaldehyde-propylene, cyclohexanonpropylene processes.
(4) Acetylene production
Hydrogen plasma-jet process for the production of acetylene starting from methane was reported by USSR chemist, and the necessary electrical energy is said to be 10kWhr per 1 kg of acetylene. Spark and plasma-jet processes are now being closed up as the acetylene productions processes.View full abstractDownload PDF (645K) -

JOURNAL FREE ACCESSA Survey was made on the recent developments of oil sands deposits in Canada based upon the data from published articles including PD 13 of 7rh World Petroleum Congress. Same informations obtained during the author's trip in Canada and the United States as a member of “Oil Sands Survey Mission” were also presented. Geological and geophysical features of the deposits were briefly introduced. The two ways of bitumen recovery from the oil sands, namely, mining of sands followed by hotwater separation and “in-situ” recovery by steam injection, were described. Bitumen up grading processes to produce synthetic crude were shown. Inspections of bitumen and synthetic crude properties were also given. Commercial operation of GCOS is going to start in this autum in Athabasca, nothern part of Alberta, Canada.View full abstractDownload PDF (1004K) -

JOURNAL FREE ACCESSDuring recent years strong efforts have concentrated on manufacturing huge vessels, as a result, a 200.000 DWT tanker is now placed in service and it is also planning to build a 500, 000 DWT tanker.
However, there exist many problems to have to be solved in the tendency of being mammoth tanker.
In this paper, it is described a summary of the problem associated with huge vessels which is mainly investigated in Japan.View full abstractDownload PDF (809K) -

JOURNAL FREE ACCESSNowadays the problem of air pollution has come to be very troublesome problem in our daily life, and many people, i, e plant operators, engineers, smoke-control officers, executives and others are doing their best to abate and control air pollution.
In this report, the auther described the technology to control air pollution in petroleum refineries.
That is, chapter 1 and 2 state the law to control air pollution, and the administrative guidance by the whole investigation to control industrial public nuisance.
Chapter 3 and 4 state main air pollution sources and sulfer balance at petroleum refineries.
Chapter 5 and 6 state the technology of desulfurization and sulfer recovery.
Chapter 7 states the future trends for abating air pollution.View full abstractDownload PDF (1448K) -

JOURNAL FREE ACCESSAnovel analyser for the determination of sulfur content in fuel oils has been devised. This apparatus is available for the monitoring of sulfur content of the petroleum intermediates and product, such as gas oil, distillate fraction, residual oil, and plays a role as a stream analyser. The sulfur concentration may be measured up to 4% by weight, using this apparatus. Operational specifications regarding to the fuel samples are given as follows:
(1) density 0.78∼0.94
(2) carbon-to-hydrogen ratio 6∼9
(3) maximum inlet temperature 110°C
(4) maximum inlet pressure 7kg/cm2
The data obtained with this device are compared with those based on the speified in ASTM D-129. The difference between these experimental resulte is of the order of ±0.05%.View full abstractDownload PDF (477K) -

JOURNAL FREE ACCESSThe contents of Ge and Ga were determined by the colorimetric analysis with 12 samples taken from different colums of 3 lignites seams and 3 coals seams in Japan.
Samples a) were taken from the top or bottom of coal seams, and samples b) were from the middle of coal seams.
The contents of Ge of samples a) were greater than that of samples b), but the same phenomena cannot be found in the contents of Ga.
12 samples were treated with hot water, hydrochloric acid, hydrofluoric acid and sodium hydroxide solution under pressure.
About 5∼14% of the Ge content in samples a) was extracted with hot water, but Ge in sample b) was not extracted.
Ge in samples a) of coal treated with hydrochloric acid was lost.
It is probable, therefore, that the presence of Ge in lignite more firmly retained than in coal.
13∼50% of Ge in lignites and coals treated with hydrochloric acid was lost.
Ga in coals was not extracted with hot water or hydrochloric acid. But about 50% of Ga in coals treated with hydrofluoric acid or sodium hydroxide solution under pressure was lost.
The Author suggests that Ga was associated with the adventitious mineral matter than the pure coal substance.View full abstractDownload PDF (610K) -
