Both catalytic cracking and thermal cracking of waste polystyrene(WPS) were investigated.Fluid catalytic cracking catalyst from refinery was used in catalytic cracking of WPS.Effects of reaction temperature,reaction time and catalyst dosage on conversion of WPS,oil yield and selectivities of liquid produc...
The meaning of THERMAL CRACKING is cracking of petroleum or similar oils by means of heat and pressure alone —distinguished from catalytic cracking.
Catalytic cracking reaction dominates below around 540 ℃, and the ratio of (C_1+C_2)/i-C_4 is less than 0.6. When the reaction temperature exceeds around 610 ℃, thermal cracking reaction is the key process and the ratio of (C_1+C_2)/i-C_4 is greater than 1.2. The rate of ...
Compared to thermal cracking, the yield of catalytic cracking is higher. It can not only promote the tar conversion but also upgrade the fuel gas quality even at a low temperature of 1023 K, especially for CO, CH4, CO2, and C3H6. The tested activation energies (Ea) of tar conversion and...
THERMAL CRACKING, THERMAL HYDROCRACKIKG AND CATALYTIC CRACKING OF DEASPHALTED OILSThis paper present results of the thermal hydrothermal and catalytic cracking of heavy residues. In this investigation, ethvl acetate was used as deasphalting agent because it allows the elimination of both resins and ...
(reaction temperature,catalyst to oil ratio,contact time) have great influence on thermal and catalytic cracking reactions.There exist some points of reaction temperature inflexion for catalytic cracking reaction and thermal cracking reaction.Catalytic cracking reaction plays the main role below around 538...
a他笑得很开心 He smiles very much happy [translate] aMost of the cracking is catalytic, but some thermal cracking also takes place 大多数裂化是催化作用的,但一些加热分裂也发生[translate]
The gaseous products of cracking were analyzed for hydrocarbons using GC. Most sulfur in the feed was present in molecules heavier than dibenzothiophene and was distributed in a variety of structures. The surviving coal liquid was analyzed by LC. The results indicated that deoxygenation of phenols,...
