Secondly, the silver based catalysts modified by phosphorus, zirconium, zinc, potassium and so on using molecular sieve as carrier, which were produced by ion-exchange method, had also good catalytic performance for 1,2-propane glycol oxidation to methylglyoxal. The conversion of 1,2-propane glycol and the selectivity of methylglyoxal were both high, and the impurity such as formaldehyde and acetaldehyde in the product is little. At the condition of the temperature 300 ℃, the molar ratio of oxygen to 1,2-propane glycol 1.7:1, the space velocity 6000h~(-1), and the concentration of 1,2-propane glycol 70wt%, the conversion of 1,2-propane glycol is 90% and the selectivity of methylglyoxal is 45% on the Ag-P catalyst.

其次对采用离子交换法制备的负载在分子筛上的银系催化剂进行了研究，发现此催化剂在助催化剂磷、锆、锌、钾等的作用下对丙二醇的低温氧化脱氢具有很高的活性，可以得到较好的丙酮醛的收率，并且产物中的甲醛、乙醛副产物的量比较低；经过对Ag-P催化剂上反应条件的考察，发现当温度为300℃、氧醇比1.7：1、空速6000h~(-1)、丙二醇浓度为70wt%时，丙二醇的转化率为90%，丙酮醛的选择性为45%。

It showed that the propane recovery rate of new process would be 23%~27% higher than that of cryogen refrigeration process at the same refrigeration temperature. To increase the absorption tower pressure appropriately was good to improve the propane recovery rate. However, the choice of pressure must take the pressure of the feed natural gas and product gas into account together. The flow rate of absorbent had great effect on propane recovery rate and tower heat load.

本文实例研究表明：相同制冷温度下，冷剂制冷－油吸收复合工艺的丙烷回收率比原冷剂制冷工艺可提高23%~27%适当提高吸收塔的压力，对增大丙烷回收率有利，但吸收塔压力的确定要综合考虑原料气压力和外输气压力的大小。
