The method solves the problems better through adopting the following technical proposal that: the method takes the solid super acid consisting of the VIB group elements or the VIB group elements and the IVB group elements in the periodic table of elements and loaded on a symbiosis molecular sieve as catalyst, and naphtha with the component being C4-C10 as a raw material so as to carry out catalytic cracking reaction at a temperature of between 550 and 700 DEG C, under a pressure of between 0.01 and 0.5 MPa, at a reaction weight space velocity of between 0.1 and 4 hours and with the weight ratio between water and naphtha of between 0.5:1 and 4:1, thereby generating ethylene and propylene.

本发明涉及一种催化裂解制乙烯丙烯的方法，主要解决现有催化裂解制乙烯丙烯催化剂的使用温度高，活性低，乙烯丙烯选择性差的问题，本发明通过使用在共生分子筛上负载由元素周期表VIB族元素或VIB族元素和IVB族元素组成的固体超强酸作为催化剂，以组份为C 4 ～C 10 的石脑油为原料，在反应温度为550～700℃，反应压力为0.01～0.5MPa，反应重量空速为0.1～4小时-1 ，水/石脑油重量比为0.5～4∶1的条件下，进行催化裂解反应生成乙烯丙烯的技术方案，较好地解决了该问题，可用于催化裂解制乙烯丙烯的工业生产中。

The dose-dependent experiment revealed that Id1 antagonised E47 and Ets1 mediated transcriptional activation in a dose-dependent manner. With pGL3-870 as a template, site-directed mutagenesis of E-box and / or ETS-binding site was introduced into p16 promoter. E47 could not activate the transcription of p16 promoter with E-boxes mutated, and Ets1 could not activate the transcription of p16 promoter with EBS mutated. The synergy effect between E47 and Ets1 would occur only if the E-boxes and EBS were present. These facts demonstrated that E47 and Ets1 proteins were not recruited to the promoter by binding to other cis-elements or through interaction with other protein factors, however, they bound to DNA directly through respective consensus sequences in p16 promoter.

以pGL3-870为模板，构建了E-box或/和EBS点突变的p16启动子报告基因载体，将野生型和突变型的报告载体分别与pI-E47、pI-Etsl以及pI-E47+pI-Ets1共转染，发现E47和Ets1所诱导的转录激活作用依赖于启动子DNA上存在的各自的特异结合序列，二者的协同作用也只有当两个结合位点都存在时才会发生，说明E47和Ets1不是与其它作用元件或其它蛋白质因子相作用而被招募到该启动子的，它们是通过启动子上各自的特异结合位点与DNA直接结合的。
