At lower temperature, the interaction between the Ir particles and the adsorbed ethoxyl species is not strong enough to abstract H atom from the nearby CH3 group, and thus acetaldehyde acts as the key intermediate. Acetaldehyde can decompose to methane and CO and/or convert to acetone through decarbonylation.

低温时Ir粒子与吸附的乙氧基的相互作用的强度不足以从-CH3基团中提取H原子，此时乙醛是关键的反应中间物，乙醛可以裂解生成甲烷和一氧化碳或脱羰基生成丙酮。

It was discovered that when ethyl nitrite was introduced to the surface of catalyst, Pd ethoxyl compound was formed and simultaneously the active site Pd was transferred to the surface of catalysts with the change from Pd〓 to Pd〓. Then lined-adsorbed CO inserted into Pd alkoxyl compound to form the carboethoxypalladium complex.

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。

A common feature in all these applications is that the exponential part of the progress curve has to be first determined by certain graphical methods such as the semilog-plots.
