Experiments on purification technologies for the conversion of cornstalk biomass into the industrial product were made to produce cornstalk gas in the down-flow fixed by the gasifier. The experiment focused on the technical procedures for deoxygenation. catalytic cracking of tar, hydrogenation, etc. Quality straw syngas was produced for methanol synthesis. The catalysis of methanol synthesis for the production of cornstalk syngas was earned out in a tubular-flow integral and isothermal reactor under the pressure of 5MPa over Cu-based catalyst C301 (particle size: 0.833mm×0.351mm), a catalyst made in China. Thirty-three sets of test data were obtained.

Phenol derived from two stage water gas gasification is produced in upward, and in downward, after tar, suspension and sediment removed, phenol, which has been filtrated, pressurized and atomized, is sprayed into regenerative chamber where phenol and high temperature lattice bricks exchange heat each other and phenol get into superheated vapor, then phenol come into gasifier with making up steam and in fire layer phenol is decomposed into H 2O and CO 2 which will go on reacting with blazing carbon and fo...

两段炉水煤气气化工艺在上吹制气阶段产生含酚冷却水，下吹制气阶段，将脱除焦油、悬浮物、沉淀物并进一步过滤后的酚水加压、雾化、喷入燃烧蓄热室内与高温格子砖进行热交换，使之汽化并过热，然后与补充过热下吹蒸汽一起进入气化炉火层，酚在高温作用下分解成H2O和CO2，并进一步与炽热的炭发生反应，形成H2和CO。

Rotary vane pumps can be sealed container extraction in the dry gas, with gas if the town of devices can also be drawn in addition to a certain amount of condensable gas.

In low basicity, because of the low melting of the slag phase, it is bad for the gas-solid reaction of ferric iron oxide and separating iron from slag The research discovered: Sulfur can be deprived above 90% during direct reduction. The mechanic of desulphurization is gasification desulphur.

研究发现，在直接还原过程中可以脱除90%以上的硫，脱硫主要机理是气化脱硫，内配煤团块中的硫化物和有机硫进入气相，一部分随炉气脱离团块，一部分被配入的CaO吸收。

In gas phase, there are two reaction paths, the concerted and stepwise mechanisms, both of which produce the experimental product, hydroxamic acid; the stepwise mechanism is predominant.

在气相中均找到两条反应通道，即协同机理和分步机理，均生成实验产物氧肟酸，而且分步机理均为优势通道；除2-甲基-2-亚硝基丙烷的反应没有协同途径外，在溶剂中反应机理与气相中的类似。

The RE of TP, COD and turbidity except NH4+-N in the aeration process by adding AS and PAM for enhanced chemical phosphorus removal increased by 7.3~59.2%, 5.0~20.3% and 10.9~34.7%, respectively. Given enough dissolved oxygen, the nitrification was not affected by adding AS and PAM in the dosage range of the study. The RE of TP, COD and turbidity by postpose coagulation were better than by simultaneous coagulation, however, coagulation and sedimentation equipments were needed in postpose coagulation process. Therefore simultaneous coagulation was more suitable for transformation of AB process for chemically enhanced phosphorus removal.

曝气过程中投加AS和PAM复配化学强化除磷，总磷、COD、浊度去除率分别提高了7.3～59.2%、5.0～20.3%、10.9～34.7%，但不能提高氨氮的去除率；在溶解氧足够时，本研究投加量范围的AS和PAM的加入对硝化作用无影响；后置混凝对TP、COD、浊度的去除效果优于同步混凝，但需增加混凝沉淀设备，因此同步混凝更适合于于AB工艺的化学强化除磷改造。

There are more and more acid gas components,〓 and 〓, from petroleum refinery gasesbecause China will import mass sour crude oil in the near future. In order to improve theselective absorption behavior of desulfurizer, new sterically hindered amine desulfurizers aredeveloped.
