P.G.(Liquified Petroleum Gas) has been gradually utilized as an energy source. The author summarizes the outline of the present status of L.P.G. and natural gas in U.S.A. Englend, Italy and Germany. He also discusses on its commercial problems, cost stability of supply, etc. and concludes that it may be very disadvantageous for use only as hydrogen source, because its price is 20, 000 yen/tin Japan. The profitable utilization processes are as follows: 1) preparation of Olefins, 2) preparation of asetylene, 3) partial oxidation by air, 4) preparation of nitrogen compounds, 5) other syntheses.
