本人英語水平較差，求助各位高手給翻譯一下，不勝感激。 本論文在實驗室前期研究采用類固相法低成本合成Beta沸石工作的基礎上，按照優(yōu)化后的合成方案進行中試放大試驗：進一步優(yōu)選現(xiàn)有的工業(yè)化合成原料，向可實現(xiàn)工業(yè)化生產的原料及工藝過渡；采用添加晶化促進劑方法進一步優(yōu)選晶化促進劑、物料配比及晶化時間；確定適合本反應釜的攪拌器類型。解決放大實驗過程中遇到的問題，以達到節(jié)約原料及能耗、提高生產效率及產品質量，提高Beta沸石綜合性價比，進一步降低生產成本的目的。使用本方法按不同的投料硅鋁比成功中試放大合成出一批Beta沸石產品，對這批產品進行了XRD，XRF，F(xiàn)T-IR，SEM，Py-IR，NH3-TPD及N2吸附等全面表征分析。 以中試放大合成不同硅鋁比的Beta沸石為活性組分，將其引入模式催化劑中，在微活評價裝置上測試其催化活性，并優(yōu)選活性較好的樣品在固定流化床上裝置上考察其催化裂化性能。最終得到一套類固相法低成本合成Beta沸石以及性能檢驗的中試方法，為之后的工業(yè)生產積累經(jīng)驗。 |

| 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. |

| This paper has a research on the pilot-plant test in a optimized way ,which based on the early laboratory research on the solid phase method to obtain the low cost zeolite Beta .We prefer the industry raw material to achieve the commercial process .We add crystallization promoter to further optimization of crystallization promoter mmaterial composition and crystallization time and determine the suitable for agitator type of reactor .In this way ,we can solove the problem encountered in the laboratory and we can reach such a purpose ,saving raw materials and energy consumption ,improving production efficiency and product quality ,improving the comprehensive performance of zeolit Beta .In this way ,we have successfully synthsised a batch of zeolite Beta ,and we have totally analysised the product with XRD ,XRF ,FT-IR ,SEM ,PY-IR ,NH3-TPD ,and N2 absorption .We try to zoom in synthesis of zeolite Beta for active components of different silica alumina ratio, which is introduced into model catalysts, testing their catalytic activity on evaluation of micro-device, and selection activity better samples at fixed fluidized-bed catalytic cracking unit study on the performance .At last we achieved a suit of solid phase methods to synthesis the zeolite Beta ,which contribute to the industry product . |
