| titleOfInvention | Process for preparing an adsorbent which is loaded with an oil |
| abstract | The present inventionn n n a) extracting oil from the oil crude product by using supercritical fluid extraction to obtain a loaded supercritical fluid (SCF);n n n b) expanding and then heating the loaded SCF of step a) to obtain a reduced SCF phase of liquid phase and in-loading;n n n c) optionally reducing the pressure on the SCF of step b) and / or increasing the temperature under adsorption conditions;n n n d) introducing the SCF of step b) or c) into the fixed bed adsorbent to obtain an adsorbent loaded with purified oil and pure SCF;n n n e) feeding the liquid phase of step b) to the extraction device of step a) as reflux;n n n f) pressing and adjusting the pure SCF of step d) to extraction conditions;n n n g) recycling the pure SCF to the extraction apparatus of step a).n n n The invention also includes a method of purifying oil from an oil crude product by desorbing the adsorbed oil.n n n The present inventionn n n A) using supercritical fluid extraction (SFE) to extract oil containing fractions with high volatility components from crude synthesis or natural oil mixtures to produce raffinates and loaded supercritical fluids containing low volatility components of the crude product ( Obtaining SCF);n n n B) After expanding the loaded SCF of step A), it is heated to obtain a liquid and unloaded gaseous phase containing oil and highly volatile components (step B-1) or to obtain a phosphorus-loaded reduced SCF and liquid phase. (Step B-2);n n n C) optionally reducing the pressure on the in-loading reduced SCF of step B-2) and / or increasing the temperature under adsorption conditions;n n n D) optionally introducing the in-loading reduced SCF of step B-2) or step C) into a fixed bed adsorbent to obtain an unloaded gaseous and oil loaded adsorbent;n n n E) collecting the unloaded gas phase of step B-1) or step D) in the vessel and controlling the content of gaseous components;n n n F) optionally supplying pure gas to the vessel of step E) to ensure the same gas composition over the entire process time;n n n G) feeding part of the liquid phase of step B-1) or both of the liquid phase of step B-2) to the extraction apparatus of step A) as reflux at the temperature and pressure of the same column;n n n H) pressurizing the gas phase of step E) or step F) and then cooling to separation conditions;n n n I) recycling the SCF of step H to the extraction device of step A);n n n J) optionally feeding the liquid phase of step B-1) to a second extraction device;n n n K) extracting a fraction of the high volatile components from the extract of step B-1) using SFE to obtain loaded SCF and pure oil as raffinate;n n n L) treating the reflux and the SCF as disclosed in steps B-1) to I);n n n M) collecting oil at the bottom of the column as raffinaten n n It further comprises a method of purifying the oil, optionally in combination with a method for producing a high-loaded adsorbent comprising a. |
