Five models were used to investigate the "Changdong"" s anti-tumor effect: mice S180 sarcoma solid model, mice liver cancer H22 solid model, mice Lewis lung cancer model, as well as human liver cancer QGY and colon cancer LOVO implanted in naked mice; mice liver cancer H22 was also used to evaluate the enhancive effect of "Changdong" when it was co-applied with other anti-tumor agent or with radiotherapy; The "Changdong"" s cytotoxic effect in vitro on such tumors as QGY, LOVO, lung cancer A549, breast cancer MCF-7, as well as mice leukemia P388 was observed through MTT method. And investigate the effect of "Changdong" on proliferation of spleen lymphocyte, on activity of NK cell and on synthesis of IL-2 in mice bearing Lewis lung cancer, respectively. With propidium iodide straining, cell aigptosis and cell circle were analyzed by flow cytometry. Result:"Changdong" has an evident tumor inhibitive effect on mice tumor model as well as human tumor implanted in naked mice with a quantity-effect relationship.

A process for partial conversion and low-temp transform of CO in the synthetic ammonia plant where coal is used to generate gas features that the Fe-Mo catalyst for partial conversion of CO, anti-poisoning agent and Co-Mo catalyst for low-temp conversion are used and the temp of semi-water gas is controlled to 200-260 deg.C at entering anti-poisoning layer, and 150-250 deg.C at the segments of said Co-Mo catalyst layer, and lower than 300 deg.C at bed layer to prevent high-temp reversal of sulfurizing reaction and make the catalyst activity optimal. Its advantages are long service life of catalyst, low system resistance, saving energy and convenient operation.

本发明是中小合成氨厂以一种CO部分转化抗毒保护层配低温变换的工艺，涉及煤造气合成氨厂0.6～2.0MPa半水煤气变换工艺流程，该工艺用铁－钼CO部分转化催化剂、抗毒剂，配钴－钼低变催化剂，半水煤气进入部分转化抗毒层温度为200～260℃，进钴－钼低变催化剂各段温度为150～250℃，床层温度控制在300℃以内，避免高温下反硫化反应发生，保护催化剂活性处最佳状态，寿命延长、系统阻力小、节汽、节电，具有比其他变换工艺更好地节能效果，操作方便，有效生产时间长，经济效益显著等特点。
