实验结果表明：回流比对甲缩醛收率和塔顶甲缩醛纯度的影响不同于一般的精馏过程，存在一个最优回流比，本过程最佳回流比在1-2之间；提高催化剂浓度，甲缩醛收率和塔顶甲缩醛纯度均增加；提高进料醇醛摩尔比也会提高甲缩醛收率；进料总流量对甲缩醛的收率的影响十分明显，进料总流量减少可以使甲缩醛的收率得到明显提高。

The active reaction between steam and carbon became severely. SBET of the steam activated carbon reached the maximum after activated at 700℃, which was 830.59m2/g, however, the yield and microporosity were as low as 3.21%和16%, respectively. H3PO4 and ZnCl2 activation processes can obviously increased SBET and yield.

It was found that the samples PVP-PdCl2-CdCl2 and PVP-PdCl2-HgCl2, compared with PVP-PdCl2, exhibited much higher catalytic activity and dechlorination selectivity, and the yields of the coupling by-products were obviously decreased. For example, when p-chloroaniline was used as substrate, the reaction time was shortened to 1/8, and the yield of dechlorination product was about 25 times as much as the original one, and when p-chlorotoluene was used as substrate, the yield of coupling by-product catalyzed by bimetallic catalyst was 1/390 of that catalyzed by monometallic catalyst.

与负载型单金属催化剂PVP-PdCl2相比， PVP-PdCl2-CdCl2和PVP-PdCl2-HgCl2对氯代芳烃脱氯有高得多的催化活性和脱氯选择性，且偶联副产物显著减少；以对氯苯胺为底物时，双金属催化下的反应时间缩短为单金属催化下的1/8，而脱氯产物收率提高25倍；底物为对氯甲苯时，双金属催化下的偶联副产物仅为单金属催化下的1/390。

The yield of morpholine can be 35% and the yield mixed alcohol can be 42% under temperature of 210℃, pressure of 2.0 MPa, the mass ratio of the water and morpholine by-product was of 1:1, using sodium hydroxide as catalyst, and the amount of 1.5% for the by-product, reaction time of 4 hours.

在210℃，2.0MPa下，水与副产物的质量比为1：1，采用氢氧化钠为催化剂，用量为副产物的15%，反应时间为4小时，吗啉的收率可达35%，混合醇的收率可达42%。

The yield and the utilization rate of solar energy and heat increased by more than 20%. It showed that this new multiple cropping pattern is an effective way to further increase yield in this region.
