精萘生產(chǎn)工藝及其技術(shù)進(jìn)展

精萘的生產(chǎn)主要依賴于工業(yè)萘的提純過程,目前常用的生產(chǎn)工藝包括區(qū)域熔融法、分步結(jié)晶法、催化加氫法和動(dòng)態(tài)結(jié)晶法等。其中,分步結(jié)晶法和動(dòng)態(tài)結(jié)晶法因其高效性和低能耗的特點(diǎn),成為近年來研究的熱點(diǎn)。例如,乳化結(jié)晶法通過使用特定的乳化劑和輔助劑,能夠有效提高精萘的產(chǎn)率和質(zhì)量,實(shí)驗(yàn)表明其產(chǎn)率可達(dá)到90%以上。

The production of refined naphthalene mainly relies on the purification process of industrial naphthalene. Currently, commonly used production processes include regional melting method, stepwise crystallization method, catalytic hydrogenation method, and dynamic crystallization method. Among them, the stepwise crystallization method and dynamic crystallization method have become hot research topics in recent years due to their high efficiency and low energy consumption. For example, the emulsion crystallization method can effectively improve the yield and quality of refined naphthalene by using specific emulsifiers and adjuvants, and experiments have shown that its yield can reach over 90%.

除了傳統(tǒng)的物理方法,化學(xué)方法如催化加氫法也在不斷優(yōu)化。該方法通過在催化劑的作用下,將工業(yè)萘中的雜質(zhì)轉(zhuǎn)化為易于分離的副產(chǎn)物,從而提高精萘的純度。近年來,研究者還嘗試將動(dòng)態(tài)結(jié)晶與靜態(tài)結(jié)晶相結(jié)合,以進(jìn)一步提升精萘的生產(chǎn)效率和產(chǎn)品質(zhì)量。

In addition to traditional physical methods, chemical methods such as catalytic hydrogenation are also constantly being optimized. This method improves the purity of refined naphthalene by converting impurities in industrial naphthalene into easily separable by-products under the action of a catalyst. In recent years, researchers have also attempted to combine dynamic crystallization with static crystallization to further improve the production efficiency and product quality of refined naphthalene.

隨著技術(shù)的不斷進(jìn)步,精萘的生產(chǎn)工藝正朝著更高效、更環(huán)保的方向發(fā)展。未來,隨著新技術(shù)的推廣應(yīng)用,精萘的生產(chǎn)成本將進(jìn)一步降低,同時(shí)其產(chǎn)品質(zhì)量也將得到進(jìn)一步提升,為下游產(chǎn)業(yè)提供更優(yōu)質(zhì)的原料支持

With the continuous advancement of technology, the production process of refined naphthalene is developing towards a more efficient and environmentally friendly direction. In the future, with the promotion and application of new technologies, the production cost of refined naphthalene will be further reduced, and its product quality will also be further improved, providing higher quality raw material support for downstream industries
