| 摘 要： | 在以分子筛为催化剂的甲醇转化研究领域中，最为成功的是甲醇在ZSM-5分子筛上转化制汽油的研究。由于在孔道结构以及酸性质上，ZSM-5型分子筛有着不同于HM、HY等其他分子筛的特点，使得它在甲醇转化制汽油的反应中有着其他分子筛不可比拟的优势。

| Abstract: | The methanol conversion over HY zeolite was studied at 1atm, 280℃~360℃. The effects of temperature, GHSV, and reaction time on the performance of reaction of methanol were discussed. The results showed that HY catalyst gave isoalkanes with high selectivity. Higher temperature(280℃~340℃) and lower GHSV decreased the selectivity to dimethyl ether and increased that to C2，C3，i-C4 ，i-C5. With the further increase of temperature, the selectivity of C2，C3 increased while that to i-C4 ，i-C5 decreased. The selectivity to isoalkanes decreased quickly with the reaction time. |
