Description
工程（３）では、工程（１）の水素化脱硫処理油を工程（２）で軽質分をストリップ（除去）した後、温度１５０℃〜２５０℃、圧力１〜５ＭＰａの条件下でゼオライトにより直鎖飽和炭化水素を１０容量％以上抽出除去する。
直鎖飽和炭化水素の除去の抽出温度は１５０℃〜２５０℃であり、好ましくは１８０〜２００℃である。抽出温度が１５０℃未満の場合、十分な直鎖飽和炭化水素の除去速度が得られない。一方、２５０℃を超えると、直鎖飽和炭化水素の除去効率が低下する。また、この時の圧力は、１〜５ＭＰａであり、好ましくは１．５〜３ＭＰａである。圧力が１ＭＰａ未満であると十分な直鎖飽和炭化水素の除去速度が得られない。一方、５ＭＰａを超えると十分な直鎖飽和炭化水素の除去速度が得られない。直鎖飽和炭化水素の除去に使用するゼオライトは特には限定されないが一般的にはＡ型ゼオライトが使用され、その中でもモレキュラーシーブ５Ａが好ましい。以上の条件で、直鎖飽和炭化水素を１０容量％以上、好ましくは２０容量％以上抽出除去することが必要である。
In step (3), the hydrodesulfurized oil from step (1) is stripped (removed) of light components in step (2), and then straightened with zeolite under conditions of a temperature of 150 ° C. to 250 ° C. and a pressure of 1 to 5 MPa. Extract and remove 10% by volume or more of chain saturated hydrocarbons.
The extraction temperature for the removal of the linear saturated hydrocarbon is 150 to 250 ° C, preferably 180 to 200 ° C. When the extraction temperature is less than 150 ° C., a sufficient removal rate of linear saturated hydrocarbon cannot be obtained. On the other hand, when it exceeds 250 degreeC, the removal efficiency of a linear saturated hydrocarbon will fall. Moreover, the pressure at this time is 1-5 MPa, Preferably it is 1.5-3 MPa. If the pressure is less than 1 MPa, a sufficient removal rate of linear saturated hydrocarbons cannot be obtained. On the other hand, if it exceeds 5 MPa, a sufficient removal rate of linear saturated hydrocarbons cannot be obtained. The zeolite used for the removal of the linear saturated hydrocarbon is not particularly limited, but generally, A-type zeolite is used, and among these, the molecular sieve 5A is preferable. Under the above conditions, it is necessary to extract and remove linear saturated hydrocarbons by 10 volume% or more, preferably 20 volume% or more.
