    Utilization of LPG for motor vehicles has long been accepted in America, but it is in recent years in Japan.To use LPG for motor vehicles has many more advantages than to use gasoline or heavy fuel oil, but there still remain some defects to overcome.
    The author showing several ways of LPG use for moter vehicles and their merits and demerits, pointed out the problems to solve in future comparing those obtained in gasoline and diesel engines.
    In Japan large diesel cars are well diffused which pay low cost of fuel, and so it is difficult that LPG may be sabstituted for that.However, LPG-powered engine produces less toxic exhanst and little exhanst of unburned hydrocarbon which induces smog From the viewpoint of the abatement of air pollution, LPG will have to be utilized for city bus, Truck, etc.

  • LPG-powered Motor Vehicles

    -LPG-powered engine has been being diffused in America.This entirely depends on the following advantages LPG has, i.e.easy to be liquefied, to be of high octane, to lengthen engine's life, to contain litte carbon monoxide in the exhaust, to be of low cost.These characteristics are proved by bench and field tests (motor vehicles and fork-lift).Moreover, attempts are made to use LPG supplementarily for dieselengine.
    Calculating the diverging point of commercial profit, it shows about 2 or 2.5 years for the so-far gasoline-powered small fork-lift. Although it cannot be decided indiscriminately, it may suggest a certain standard to the users.
    Meanwhile the switchover system of LPG-gasoline.is practically apphed for the engine, as per which it is an effective measure during the cold winter.
    In spite of these advantages, LPG-powered engines have not been spread widely.It is necessary to make efforts for enlightenment of the LPG-powered engine as well as improvement of its equipment.

  • Studies on the Oxidation of a Taiwan Coal

    -One of the typical bituminous coals of Taiwan, Nantswang coal, was subjected to oxygen-oxidation in alkaline slurries. The effects of the variables such as temperature, time, oxygen pressure and agitation velocity were studied to determine the conditions for the maximum yield of “water soluble” acids. An analysis was also made fer the product obtained under such conditions.

  • Studies on the Hydrodesulfurization(II)
    Sulfurization and Reduction of V2O3-MoO2 Catalyst
    Kimio Tarama, Shiichiro Teranishi, Kentaro Hattori, Mitsuro Higashi

    Sulfurization and reduction of V2O3-MoO2 catalyst have been studied kinetically.V2O3 is not sulfurized with H2S at lower temperature than 480°C, but MoO2is sulfurized to MoS2+x (x=0.3) with CS2, H2S, and thiophene in the temperature range 400∼480°C.The reduction of MoS2+x with H2 is difficult at 400°C, but it proceeds slowly to MoS1.86at 600°C.
    Sulfurization rate of this MoS1.86were measured.The kinetic orders of sulfurization were1.2th, 0.5th and 0.9th for CS2, H2S and thiophen respectively, and the reactivities of these compounds decreased in the preceding order.
    The catalyst of molar ratio V2O3/MoO2=6was sulfurized most easily, so it was understood that the sulfurization process was the main step in the mechanism of hydrodesulfurization, for the desulfurization activity per unit area of catalyst was maximum at this composition as shown in the preceding paper.
    Further, from the results of electric conductivity measurements of the catalyst, it was supposed that the catalysis displayed activity under the co-operation betweenV2O3 (n-type semiconductor) and MoS2-x (p-type semiconductor).

    The Oxo Reaction of C4-Olefines by Continous Contact Apparatus

    -C4 olifines were continously hydroformylated in the presences of cobalt naphthenate as catalyst and Pd-zeolit as promoter like the preceding reports.The reaction temperature was necesary to keep over 140°C, presumably: owing to the fact that the charge stock contained much isobuten of smaller reaction velocity
    Addition of Pd-zeolite as promoter was equally useful as in theanot-her experiments.The content of high boiling points fraction in the product was about 15%, the yield of amylalcohol being 80-85%.
