  coke
An empirical catalyst deactivation function is incorporated into the model accounting for the loss in activity because of coke formation on the catalyst surface during the long-term operation.
      
Formation of coke in thermal cracking of jet fuel under supercritical conditions
      
Continuous-flow reactor experiments were carried out to study coke formation from thermal cracking of home-made jet fuel RP-3 under supercritical conditions.
      
The mechanism and precursor of coke forming were analyzed.
      
More than 90% of coke deposits are carried away by the supercritical fluid, which has strong capabilities of extraction for coke deposits and their precursors.

  the coke
There were 17.1 wt-% of iron and 11.1 wt-% of chromium found on the coke surface detected by energy dispersive spectroscopy (EDS) which suggests carburetionon alloy.
      
The model including the structure inhomogeneity of the coke of a typical "charring" heat-shielding material (HSM) is used to investigate the process of high-temperature heat and mass transfer in a layer of HSM coke.
      
The deactivation by coke is explained by the poisoning of α-sites, whose concentration decreases linearly with an increase in the coke content, rather than by the blocking of zeolite pores.
      
The coke amount equivalent to 100-120 benzene molecules is shown to result in the deactivation of one active site.
      
The available linear and exponential relations between the activity and the coke concentration are the specific cases of these equations.

  cokes
The samples of petroleum cokes obtained from the feedstock of different compositions were analyzed for the sulfur content, and their microstructure was thoroughly studied in detail.
      
Low-temperature oxidative modification of lignites and lignite-based cokes
      
The kinetics of oxidation of lignites and cokes with ozone in the gas and liquid phases and the composition of oxidation products were studied.
      
Changes in the composition of functional groups on the surface of lignites and cokes were determined IR spectroscopically.
      
The designing and installation of vent-cap aim to get relatively uniform gas distribution, to reduce the temperature fluctuation of cokes at outlet and realize stable operation of CDQ apparatus.

Several kinds of bituminous coal higher in volatile matter content and with moderate plasticity were rapidly pre-heated by using a solid heat carrier to a given temperature for a given period of time. The plasticity of coal after this treatment changes regularly with the preheating temperature and the period Of heating, it was found that the plasticity decreased to a minimum as the preheating temperature increased, andthen increased to a value much higher than that of the untreated coal when the preheating temperature...

Several kinds of bituminous coal higher in volatile matter content and with moderate plasticity were rapidly pre-heated by using a solid heat carrier to a given temperature for a given period of time. The plasticity of coal after this treatment changes regularly with the preheating temperature and the period Of heating, it was found that the plasticity decreased to a minimum as the preheating temperature increased, andthen increased to a value much higher than that of the untreated coal when the preheating temperature raised further. The changes of the % of thermal bitumen extracted and the mechanical strength of the coke obtained from the treated coals exhibit also the same regularity.

將有一定粘結性的高揮發分烟煤用固体热載体进行快速預热,至一定的溫度并保持一定恒溫时間,使其进行热分解后再冷却。这样处理后的煤,其粘結性的变化因預热溫度升高而下降,到最低后又复上升。有的可以超过原煤样的粘結性,这种变化規律也表現在处理后煤样的热瀝青抽出量及焦炭强度上。快速預热时,揮發分的析出量較少,但也降低了揮發分,对煉焦时有减少收縮的作用。預热对于没有粘結性的高揮發分烟煤的作用则不明显。

本文叙述了国产合成1号聚合汽缸油、2号聚合汽缸油、1号縮合汽缸油和2号縮合汽缸油的性質評价結果,以及从玉門原油制造的过热汽缸油的性貭評价結果,并和一种商品过热汽缸油的性貭作了比較。說明聚合油1号的性能比被研究的这种商品过热汽缸油要好得多,有可能在400°以上的过热蒸汽溫度下使用。由玉門油制出的汽缸油經过高真空蒸餾和精制后,除揮发損失略高于聚合油1号和抗氧化安定性两者相等外,生成焦炭性能和潤滑性能均比聚合油1号好。

In view of the weak caking property, and high softening point of Datong coal, and of the high fusinite content of each coal in the experimental charge, a way of using more Datong coal in the coking charge is suggested. That is, the charge should contain a very fat coal with good caking property, and the quantities of low volatile lean coal in the charge should be reduced when Datong coal is increased. This has been proved by experimental results. Coke oven results indicate that the strength of the coke obtained...

In view of the weak caking property, and high softening point of Datong coal, and of the high fusinite content of each coal in the experimental charge, a way of using more Datong coal in the coking charge is suggested. That is, the charge should contain a very fat coal with good caking property, and the quantities of low volatile lean coal in the charge should be reduced when Datong coal is increased. This has been proved by experimental results. Coke oven results indicate that the strength of the coke obtained using 35% Datong coal is the same as that produced with 10% Datong coal (charge No. 1). On altering the crushing method, the coke strength using 45% Datong coal also meets the metallurgical requirements.

根据大同煤粘结性弱和软化点高的特点,以及试验配煤中各种煤的丝炭质含量高的特点,提出了在炼焦配煤中多用大同煤的途径.即配以粘结性好的强肥煤,井在多用大同煤的同时,相应降低瘦煤用量.牛工业铁箱试验结果表明,在配煤中大同煤用量增加到35%时,焦炭强度和现行配煤(大同煤占10%)所得焦炭强度基本一样,甚至大同煤用量45%的配煤所得焦炭强度也能符合冶金要求。
