Besides policy factors, five methods of cost - cutting of biodiesel are reviewed, including new raw material with higher oil content, shorter regeneration cycle, which is suitable for infertile soil and different climatic conditions ; heterogeneous catalysts ; new technologies ( e. g. supercritical methanol and ultrasonics ) ; higher added value utilization of by - product glycerin with simple method ( propylene oxide chloride, 1, 3 - propanediol, pyruvic alcohol etc. ) and moderate scale of production
摘要綜述了除政策因素外，降低生物柴油生產成本的5種方法：選擇含油率高、再生周期短、適應貧瘠土地及不同氣候條件的新型植物原料；研究新型固體催化劑；引入新工藝（超臨界法和超聲波法） ；使用比較簡便的方法將廢棄的甘油轉化為高附加值的產品（環氧氯丙烷、 1 ， 3 -丙二醇、丙酮醇等）以及適度生產規模等。The results showed that the environmental pressure and catalysts have various actions on the thermal decomposition characteristics of the propellant and its ingredients. the burning rates of the gap / tmo fuel - rich propellants were measured by use of the pipe - connected unchoked ducted rocket testing facility
實驗結果表明，在不同壓強下，貧氧推進劑各組分的熱分解特徵有所不同；在同一壓強下， tmo催化劑對貧氧推進劑中不同組分的催化作用不盡相同；同一催化劑，在不同壓強下對同一組分的催化能力也不同。The experimental results also showed that there is a correlation between the burning rates of gap fuel - rich propellant and the thermal decomposition temperature of kp and gap
具體表現在： gap tmo貧氧推進劑的燃速與常壓下tmo催化劑對ap kp gap模擬貧氧推進劑中gap和kp熱分解的催化作用相關。The gap fuel - rich propellant showed short ignition delay time, high burning rate, and sensitive to variation of gas generator pressure. the results also showed that some tmo, such as moo3 and 0203 can increase the burning rate of the gap fuel - rich propellant
測試結果表明， gap貧氧推進劑具有點火延遲期短、燃速高、燃速對壓強敏感性強等優點，且某些tmo催化劑如moo _ 3 、 co _ 2o _ 3等可顯著提高gap貧氧推進劑的燃速。The processing techniques to manufacture gap net polymer and gap fuel - rich propellant were determined by means of careful selections of curing parameter, proper curative and crosslinking agent, addition of stabilizer and etc. the mechanic property of gap propellant was modified by addition of chain extender. as a result, the gap fuel - rich propellant was developed. by means of dsc and pdta methods, the thermal decomposition characteristics of gap model fuel - rich propellant and its ingredients at both 0. 1 and 0. 5 mpa were investigated
通過調節固化參數，選擇合適的固化劑和交聯劑體系，添加安定劑以及改進工藝步驟等方法，解決了gap預聚物及gap貧氧推進劑制備工藝中的關鍵技術；採用添加擴鏈劑的方法改善了gap貧氧推進劑的力學性能；最後研製出一個可實用的gap貧氧推進劑配方。分享友人
