    Although there are many processes for the production of synthesisgas from various resources, the, gas usually requires the rigorous removal of sulfurcompounds in it. There are more difficulties in purifying the gas made from pulverizedcoal than other gases, such as water gas from coke.
    The U. S. Bureau of Mines has studied these over 10 years on the purification of thesynthesis gas made directly from coal and has made much contribution to this field.While, the Rectisol process, invented in Germany, was proved to be extremely efficientin practice at the SASOL plant.
    This paper briefly describes the recent developments in the world, of the desulfurizationprocess of the synthesis gas together with the analytical method of sulfur compoundsin the gas.

    Regard to recovery and utilisation of sulfur in coal, auther discusses three items as follow,
    1)Recovery of pyrite in coal preparotfon.
    It has been commented on this question as uneconomical in Japan.
    But as results of some experiences with Miike coal, , auther feels a provability of pr-actical value in the recovery of pyrite from sulfur rich coal such as Miike.80
    2)Utilisation of H2S recovered from coal gas.
    As industrial utilisations, auther introduces the manufacturing of sulfuric acid with Chamber and Wet-contact processes, the elemental sulfur with Claus process and thio-urea with Miike process.
    As the material for Chamber process, the recovered H2S, Containing HCN, has a merit to save the comsumption of HNO3.
    Auther writes some characteristrc constructrons of Claus process, installed in U. S. A, Germany, Bergium and Miike, Japan.
    As supplements for, wet contact process, Auther introduces the perfomance results of vacuum carbonate process, and progresses of coffin process.
    As a promissing dry desulfurization method, Contineous Alumina process is also dis-cussed.
    3)Recovery and utilisation of dilute H2S and SO2
    Auther proposes a new method for making elemental sulfur from dilute H25, which isnot combustible in common furnace.
    The method is consists in oxydation of H2S under the electric dicharge. Auther also introduces some instances to get (NH4) 2SO4 and sulfur from dilute SO2contained in the flue gas of power station.

  • Rational treating of Sulfur Compounds in Petroleum
    Nobuo Yasui
    1958 Volume 37 Issue 2 Pages 81-91

    The rational treating of sulfur compounds in petroleum, especially in light petroleum fractions, is one of the main subjects of petroleum refining, and nu-merous researches were performed concering the conversion of the sulfur compounds to less harmful forms-sweetening, or removing them from petroleum-desulfurization, and yet many unexamined points have been left behind.
    In this paper, an outlook is made over the types of sulfur compounds in light pet-roleum fractions, the chemical behaviors of them at the refining and other processes, the various effects of sweetening and desulfurization and a comparison of present treating processes.

    Lubricating oils produced from Middle East crude oils, a great deal of which are now imported in Japan, have much sulfur.
    Therefore, we can not ignore the influence of sulfur compounds against the properties of lubricating oils.
    To study for sulfur compounds in petroleum, it is necessary to separate pure sulfur compounds or to type-analyse the sulfur compounds.
    Now, there are many reports for the separation of sulfur compounds in light petro-leum oils, but, there are little reports for lubricating oils.
    On the otherhand, it is understand that the properties of synthetic sulfur comp6unds are very differed by type
    Therefore, firstly I describe the kinds of sulfur compounds and the properties of synthetic sulfur compounds, and then, the separation and the type-analysis of natural sulfur compounds in petroleum, the desulfurization of lubricating oils, the oxidation inhibiting properties, the corrosion preventing properties and the extreme pressure lubricating properties of sulfur compounds against lubricating oils, finally the merits and the demerits of sulfur compounds in lubricating oils.

    The authors reported on the outline and operating results. The Uni-fining Unit Unit was designed by U. O. P. as being the first unit in Japan with its operation started as from April 1957. Also, they(authors)reported a very smooth operation of the Unifiner and that the desulfurization percentage of kerosene and gas oil would be above 95%.

  • Some Problems on Low Sulfur Fuel Oils

    Most part of fuel oils used in Japan are produced from high sulfut Middle East crudes oil. Import of low sulfur crude oil or low sulfur fuel oil is difficult in accordance with the world conditions of petroleum production and Japanese petroleum policy. There are technical troubles in the productin of low sulfur fuel oils by cutback method of coking gas oil to fuel oil, catalytic desulfurization of crude oil and hydrod esulfurization of fuel oil. Therefore adequate use of high sulfur fuel oil is desired. The author discussed about the lowering of dew point of flew gas by the absorptive remove of SO3, the prevention of fuel injection nozzle pluging in Diesel engises, addition of SO, neutralizer to lubricating oil, and mixing use of high sulfur fuel oil with coke gas or low sulfur fuel in open hearth furnace.

    The behavior of sulfur in the operation of open hearth furnace when fuel oil is used for heat sonrce, is discussed. It is empirically known that the steel is sulfurized when the fuel oils containing above 0.6% and 1.6% sulfur are used at charging and early period of smelting respectively. Relation of sulfur contents of fuel oils and behavior of sulfur in .furnace are studied in the operations of commercial basic processes. Inc rease of charge unit and decrease of the times of charging and smelting are the impor tant factors to prevent sulfurization of steel. Increace of sulfur content of steel per one % increase of suefur of fuel oil is 0.006-0.016% approximately. In commercial opera tion, fuel oils of sulfur content below 1.3-1.5% are desired.
