摘要
催化裂化油漿是分餾塔底油，含有少量催化劑粉末，為防止結(jié)焦以及維持裝置的熱平衡，許多煉廠采用外甩油漿的辦法解決這一矛盾，中國每年FCC（催化裂化）外甩油漿高達(dá)750萬噸以上，大量的外甩油漿一般作為廉價(jià)的鍋爐燃料，不僅浪費(fèi)了能源，而且油漿中的固態(tài)粉末會(huì)粘附在爐膛中、管壁上，降低傳熱效率。油漿中含有催化劑粉塵、膠質(zhì)、瀝青質(zhì)、稠環(huán)芳烴和烯烴，可利用油漿中大量高沸點(diǎn)的重芳烴、飽和烴制作活性炭纖維、橡—塑軟化劑、高溫導(dǎo)熱油、環(huán)保型輪胎橡膠油；FCC油漿中的稠環(huán)芳烴進(jìn)一步縮合可生產(chǎn)炭黑、針狀焦。
本文在對(duì)催化裂化油漿和其中的平衡催化劑粉末的性質(zhì)及其組成做了一定的分析后，對(duì)油漿的石油膠體分散體系進(jìn)行了重新認(rèn)識(shí)，將油漿看做以催化劑粉末作為分散相的核，在催化劑核以外包裹著瀝青質(zhì)作為分散相，并在瀝青質(zhì)以外由里到外按某種特性(芳香性、極性、溶解度參數(shù))遞減的規(guī)律構(gòu)成分散相核的溶劑化層，分散介質(zhì)則主要由某種特性最低的組分構(gòu)成，并與分散相達(dá)成動(dòng)態(tài)平衡形成一種穩(wěn)定的膠體分散體系。在重新認(rèn)識(shí)了油漿的這種膠體分散體系模型之后，將其考慮進(jìn)催化裂化油漿溶劑精制脫粉末過程中。
文中分別進(jìn)行了催化裂化油漿間歇式和連續(xù)式純糠醛抽提實(shí)驗(yàn)，分別得到了糠醛作溶劑的最佳溶劑抽提條件。
在提出了新的油漿固含量測(cè)定方法并綜合考慮了油漿的膠體分散體系理論模型和油漿抽提精制原理后，進(jìn)行了催化裂化油漿過濾脫除催化劑粉末試驗(yàn)，提出了兩種油漿溶劑精制聯(lián)合過濾分離脫粉末方案：第一種方案為催化裂化油漿與糠醛混合后在操作溫度為70℃，劑油比為4的實(shí)驗(yàn)條件下先萃取分離，再對(duì)抽出液和抽余液分別過濾催化劑粉末；第二種方案為先將催化裂化油漿與糠醛1:1混合加熱到100℃，進(jìn)行過濾后進(jìn)入抽提塔與糠醛抽提（劑油比為3:1），抽提后的抽出液、抽余液分別回收糠醛后獲得抽余油和抽出油，抽余油作為催化裂化原料返回催化裂化裝置，抽出油作為橡膠填充油或?yàn)r青調(diào)和組分進(jìn)行銷售。
兩種方案均能達(dá)到溶劑精制油漿，并脫除其中的催化劑粉末即對(duì)油漿進(jìn)行綜合利用的效果，可供煉廠在實(shí)際應(yīng)用時(shí)針對(duì)其的裝置實(shí)際情況以及相應(yīng)的經(jīng)濟(jì)效益進(jìn)行考量。

abstract：
Catalytic cracking slurry is fractionator bottom oil, containing a small amount of catalyst powder, to prevent coking and maintain the device thermal equilibrium, many refineries to jilt slurry outside using the method to solve this contradiction, the FCC (FCC) each year on China to jilt slurry oil is as high as more than 7.5 million tons, a large number of outside general as cheap jilt slurry boiler fuel, not only waste the energy, and solid powder will adhere to in the furnace of slurry oil, on the wall, reduce the heat transfer efficiency. Slurry containing catalyst dust polycyclic aromatic hydrocarbons, colloid and asphaltene, and alkenes, can use a large amount of high boiling point heavy aromatics in slurry oil, saturated hydrocarbon production of activated carbon fiber, rubber, plastic, softener, high temperature heat conduction oil, green tire and rubber oil; Polycyclic aromatic hydrocarbons in FCC slurry oil further condensation to produce carbon black, needle coke.
Based on catalytic cracking slurry and the nature of the equilibrium catalyst powder and do some analysis, on the slurry oil colloid dispersed system, the slurry oil as with catalyst powder as the disperse phase nuclear, wrapped in the asphalt outside the catalyst nuclear as a dispersed phase, and in the asphalt outside from the inside out by certain properties (aromaticity, polarity, solubility parameter) the law of the diminishing of dispersed phase nuclear solvation layer, dispersion medium is mainly made up of some characteristics of the lowest component, and to reach a dynamic equilibrium with the dispersed phase forms a stable colloidal dispersion system. In a new sense of slurry system of the colloidal dispersion model, to be considered in catalytic cracking slurry oil solvent refining process of powder.
Respectively in this paper has carried on the catalytic cracking slurry batch and continuous pure furfural extraction experiments, respectively obtained the optimum solvent extraction conditions of furfural as solvent.
In new slurry solids determination method was put forward and to comprehensively consider the colloidal dispersion of the slurry system theory model and the slurry after extraction of refined principle, has carried on the FCC slurry oil filter removal catalyst powder test, put forward two kinds of slurry oil solvent refining joint filtration separation powder off plan: the first kind of plan for catalytic cracking slurry mixes with furfural in the operating temperature is 70 ℃, agent oil ratio of 4 under the experimental conditions of extraction separation first, then to extract and raffinate fluid filtration catalyst powder respectively; The second scheme first to catalytic cracking slurry mixed with furfural 1:1 heated to 100 ℃, after filtering into the extraction tower and the furfural extraction oil ratio 3:1 (agent), after the extraction of extract and raffinate fluid respectively after the recovery of furfural raffinate oil and extract oil, raffinate oil return to catalytic cracking unit as a feedstock for catalytic cracking, extract oil as rubber filling oil or tar harmonic components for sale.
Two kinds of schemes can achieve solvent refined oil slurry, and removing the catalyst powder that is the effect of the comprehensive utilization of slurry oil available for refinery device in practical application for its actual situation and the corresponding economic benefits are tested.
