本人英语水平较差，求助各位高手给翻译一下，不胜感激。 本论文在实验室前期研究采用类固相法低成本合成Beta沸石工作的基础上，按照优化后的合成方案进行中试放大试验：进一步优选现有的工业化合成原料，向可实现工业化生产的原料及工艺过渡；采用添加晶化促进剂方法进一步优选晶化促进剂、物料配比及晶化时间；确定适合本反应釜的搅拌器类型。解决放大实验过程中遇到的问题，以达到节约原料及能耗、提高生产效率及产品质量，提高Beta沸石综合性价比，进一步降低生产成本的目的。使用本方法按不同的投料硅铝比成功中试放大合成出一批Beta沸石产品，对这批产品进行了XRD，XRF，FT-IR，SEM，Py-IR，NH3-TPD及N2吸附等全面表征分析。 以中试放大合成不同硅铝比的Beta沸石为活性组分，将其引入模式催化剂中，在微活评价装置上测试其催化活性，并优选活性较好的样品在固定流化床上装置上考察其催化裂化性能。最终得到一套类固相法低成本合成Beta沸石以及性能检验的中试方法，为之后的工业生产积累经验。 |

| Based on synthetizing β- zeolite by solid phase method at low cost in the earlier stages of laboratory, we have performed semi-works production according to the optimal synthetic scheme, further have optimizated the existing industrialized synthetic raw material, have realized the transition of industrialized raw material and technology; further have optimizated crystallization accelerator, material ratio and crystallization time by adding the crystallization accelerator; and have determined the stirrer suitable for agitated reactor. We have solved the problems in the course of enlargement experiment, so as to save raw materials and energy consumption, increase production efficiency and product quality, improve the comprehensive cost performance of β- zeolite, further decreasing the cost of production. We have succeeded to synthetize a number of β- zeolite products at pilot scale production by the method at the different feeding ratios of silicon and aluminium, and have performed comprehensive analysis of characterization for the adsorption of XRD, XRF, ft-ir, SEM, Py-IR, NH3-TPD and N2. We have synthetized β- zeolite with different ratios of silicon and aluminium at pilot scale production as active components, have introduced into mode catalyst, have tested its catalytic activity in micro live evaluation device, and have optimized active sample in fixed fluid bed to investigate catalytic cracking performance. Finally, we have obtained a set of solid phase method at low cost for synthetizing β- zeolite and pilot scale production of performance test, thereby gathering experience for the industrial production. |
