It becomes necessary to regenerate the molecular sieve under harsher conditions, and in extreme cases, it becomes necessary to replace it with a new one. However, this regeneration or exchange is extremely disadvantageous economically, and in order to avoid this, conventionally, high-quality oil such as Arabian Light JNOX oil or Minas crude oil, which has a relatively low content of polar substances such as nitrogen compounds, has been used. Petroleum fractions such as kerosene or light oil obtained from crude oil are hydrorefined under severe conditions of a hydrogen pressure of 95 kg/cJ or more and a liquid hourly space velocity of 0.8 to 1.0, and then subjected to adsorption separation.

For this reason, there has been a need for a method for producing normal paraffins from petroleum fractions obtained from crude oil that is inexpensive and contains relatively large amounts of polar substances such as nitrogen compounds.

方法にも適用できる。In the method of adsorbing and separating normal paraffins from a petroleum fraction using a molecular sieve, first, the petroleum fraction is fed and passed through an adsorption tower filled with the above-mentioned molecular sieve to adsorb normal paraffins in the petroleum fraction. next,
When adsorption reaches saturation, the petroleum fraction remaining in the adsorption tower is discharged and the adsorbed normal paraffin is applied to the skin. There are two methods for this: adsorption in a gas phase, depressurization and desorption in the gas phase, adsorption in a liquid phase, and replacement undergarment in the liquid phase; the present invention can be applied to any of these methods. .

０〜３５０℃の範囲で適宜、条件を選定し得る。Prior to adsorption separation using the molecular sieve, the petroleum fraction is hydrorefined. Hydrorefining is carried out in the presence of a catalyst in which metals selected from Groups 1 and 1, such as nickel, cobalt, and molybdenum, or their metal compounds are supported on porous inorganic refractories such as silica, alumina, and silica-alumina. The process is carried out under hydrogen pressure. In this case 5, in the present invention, hydrorefining under mild conditions is sufficient than the conventionally required hydrorefining, that is, hydrogen pressure of 25 to 80 kg/cm.

℃の範囲で適宜選定される。This hydrorefined petroleum fraction is first treated with clay, and this clay is preferably natural clay such as acid clay or bentonite, or activated clay obtained by treating these with sulfuric acid. White clay treatment can be done simply and efficiently using percolation or contact filtration methods. The conditions for clay treatment cannot be determined unconditionally depending on the properties of the hydrorefined petroleum fraction or the type of clay used, but usually the liquid hourly space velocity (LH8V) is 1 to 10 hr-'' and the treatment conditions are Room temperature?llll~250

温〜１００℃の範囲で適宜選定される。In this clay treatment, weakly polar substances and water are eluted from the clay. This also inhibits the adsorption capacity of the molecular sieve. To remove this, the clay-treated petroleum fraction is then brought into contact with zeolite. Both natural and synthetic zeolites are effective. In particular, A-type zeolite with a pore size of 4 or 5 pores or an As with the above-mentioned clay treatment, the contact method is preferably carried out by percolation method or contact filtration method because it is simple and efficient. In addition, the contact conditions cannot be determined unconditionally depending on the weak polar substances eluted into the petroleum fraction, the tik of water, etc., but usually the liquid hourly space velocity (LHS V) is 1 to 10 hr-1. , the contact temperature is appropriately selected within the range of room temperature to 100°C.

的な効果も有する。[Effects of the Invention] The present invention is an inexpensive method for producing normal paraffin from petroleum fractions using molecular sieves, in which a hydrorefined petroleum fraction is treated with clay and then pretreated by contacting it with zeolite. It has a special effect in that normal paraffin can be produced from a petroleum fraction obtained from crude oil containing relatively large amounts of polar substances such as nitrogen compounds without reducing the adsorption ability of normal paraffin to molecular sieves. In addition, in the present invention, since hydrorefining can be performed under milder conditions than the conventional hydrorefining, existing hydrorefining equipment can be reused and there is almost no need to construct a new one. It also has the additional effect of
