PRODUCTION OF ETHANOL,FAST & OIL AND METHANEGAS FROM SEVERAL GROPS

概要 （図表や脚注は「報告書全文」に掲載しております）

エタノール，油脂などの燃料生産を目的としてパールミレット，ダイズなど１０種類の雑穀類を栽培し植物体全体（茎葉と子実）の利用を対象とした生産量の比較検討を行った。さらにメタンガス生産のため野菜残渣のメタン発酵材料としての適性をトマトの腋芽，ブロッコリの廃葉など９種類の作物について組成の分析とメタン発酵実験により検討した。その結果，パールミレットの１０アール当たりエタノール算定生産量は６９０リットル，ダイズの油脂生産量は７０リットルであった。トマトの腋芽などの農場残渣のメタン発酵材料としての適性に関して，供試材料９種類の炭素含有率は約４０％，Ｃ／Ｎ比は平均１３，Ｃ／Ｐ比は平均９１で炭素，窒素，燐の含有率はほぼ適正であった。乾物１ｇ当たりメタンガス生成量はトマトの腋芽で６８０～７６０ミリリットル，ブロッコリの廃葉で４２４ミリリットルなど蓄糞に劣らないことが認められた。

概要 （英文）

THE AIM OF THIS STUDY IS TO GET FOUNDAMENTALINFORMATIONS TO UTILIZE BIOMASS ENERGY. 1.YIELDS OF ETHANOL AND FAT & OIL PER THE UNIT AREA FROM PEARL-MILLET,SUGER SORGHUM,SOYBEAN AND OTHERSEVEN KINDS OF MICELLANEOUS CEREAL CROPS WERE CALCULATED ACCORDING TO THEIR TO PRODUCTION RATE OF ETHANOL AND FAT & OIL FROM THE STARCH AND FAT CONTENT OF THE EXPERIMENTED CROPS GROWN AT AKAGI TESTING CENTER OF CRIEPI. THE ESTIMATED YIELD OF ETHANOL PER TEN ARE FROM PEARL-MILLET WAS690 LITRE,WHICH WAS THE LARGEST OF THE EXPERIMENTED CROPS,AND FROM SUGER SORGHUM WAS 400LITRE. THESE VALUES WERE NEARLY EQUIVALENT TO THE CASES OF SUGAR-CANE.THE ESTIMATED YEILD OF FAT AND OIL PER TEN ARE WAS 70 LITRE FROM SOYBEAN,50 LITRE FROM CASTOR BEAN,25 LITRE FROM THE SEED OF SUNFLOWER.THE YIELDS OF SOYBEAN AND CASTOR BEAN WERE TWICE AS MUCH AS THE NORMAL YIELD BUT THE SEED OF SUNFLOWER WAS ABOUT HALF AS MUCH.THESE VALUES WERE ANYWAY TOO SMALL FOR FUEL ENERGY PRODUCING PLANTS. 2.THE CONSTITUENT OF SEVERAL KINDS OF THE GRASSES AND VEGETABLE WASTES WAS ANALIZED TO FIND THEM TO BE SUITABLE FOR THE METHANE FERMENTATION FROM THE POINT OF VIEW OF NUTRIENT BALANCE.THE BALANCE OF NUTRIENT WAS MODERATE FOR C TO N AND C TO P IN GENERAL. THE CALORIES OF EXPERIMENTED FRARM RESIDUES WERE APPROXIMATELY 4,000 CAL PER ONE GRAM OF THE DRY MATTER. FOUR HUNDRED AND TWENTY-FOUR MILLILITER OF METHANE GAS (METHANE RATE:61%)WAS PRODUCED FROM ONE GRAM OF THE DRY MATTER OF BROCCOLI LEAVES,ONE OF THE VEGETABLE WASTES,IN NINE DAYS OF THE RETENTION TIME AT 30 DEG.AND THE RECOVERY RATE OF CALORIE FROM THE MATERIAL BY THE METHANE FERMENTATION WAS 62%.
