Abstract
【解決手段】メタン99mol%以上含有するとともに、エタン,プロパン,ブタンの少なくとも一つからなる高炭化水素を0.08mol%以上1mol%未満含有する自動車用液化天然ガスを燃料として使用する。この自動車用液化天然ガスは、製品液化天然ガス中の高炭化水素濃度を、炭化水素分析計24で検出し、その高炭化水素の濃度のばらつきを、精留塔3の精留条件の調節により、所定範囲内におさめることによって得られる。
【選択図】図1
Description
本発明者は、LNGの有する上記のような問題を解決すべく研究を重ねた。その結果、エタン,プロパン等の高炭化水素の量を極く少なくすることを目的として実験を重ねた。
図2に示すように、エンジンAをベンチ(図示せず)に固定し、下記の表1に示すような組成の異なるLNGを燃料として、回転速度2000rpmで10分間、エンジンAを作動させた。
上記ベンチテストにおいて、エンジンを作動させる前後でエンジン内の冷却水の温度を測定した。その結果を下記の表1に記載した。
上記ベンチテストにおいて、エンジンからの排気ガスを目視にて観察した。その結果、排気ガスが白色透明なものを○、黒色を帯びているものを×と評価し、下記の表1に併せて記載した。
24 炭化水素分析計
Claims (2)
- メタンを99mol%以上含有するとともに、エタン,プロパン,ブタンの少なくとも一つからなる高炭化水素を含有し、その高炭化水素の含有量が0.08mol%以上1mol%未満に規定されていることを特徴とする自動車用液化天然ガス。
- 原料液化天然ガス貯槽から導出した液化天然ガスを精留塔に導き、精留塔の精留作用によって液化天然ガス中に含有されるエタン,プロパンおよびブタンの少なくとも一つからなる高炭化水素を除去し、得られた精製液化天然ガスを製品液化天然ガス貯槽に貯留する液化天然ガスの製法であって、上記製品液化天然ガス中の高炭化水素濃度を、検出機で検出し、その高炭化水素の濃度のばらつきを、精留塔の精留条件の調節により、所定範囲内におさめることを特徴とする自動車用液化天然ガスの製法。
