氟硼酸銨溶液裂化催化劑Heavy oil viscosity reduction of was studied by using toluene as additive for catalytic aquathermolysis reaction in this paper
摘要以鉬酸銨作為稠油水熱裂解反應的催化劑。The brine shrimp he was prepared and purified by 67 % ammonium sulfate precipitation, deae - sepharose fast flow ion - exchange chromatography, and sephacryl column gel - filtration, and its biochemical and enzymological properties were identified in this study. it was found that the deduced molecular weight of he in sds - page is about 98. 5 kda, and its proteolytic activity was optimized at ph of 7. 5 - 8. 5 and at temperature of 40, respectively
我們利用67硫酸銨沉澱、 deae - sepharosefastflow陰離子交換柱層析和sephacryl凝膠過濾柱層析，並以酪蛋白為其蛋白酶水解活性的檢測底物、以卵膜為其卵殼裂解活性的特異性底物，從鹵蟲胚胎孵化液中分離純化出了鹵蟲的孵化酶分子，其在sds - page電泳中的分子量約為98 . 5kda 。
