The transformations of decalene, tetralene and β-n-butylnaphtalene on microspherical zeolite-containing catalysts at Deep Catalytic Cracking temperature (560°C) have been studied. It has been established that nikel on the catalyst results the increasing of the amount of unsaturated and aromatic ...
Hydrocarbon catalytic cracking catalyst and its preparation methodA catalyst for catalytic cracking of hydrocarbons contains carrier, adhesive, active cracking component and active isomerizing component. It features that said active isomerizing component is composed of modified HZSM-5 molecular sieve with ...
PURPOSE: A novel catalyst for producing olefins such as ethylene and propylene from paraffin hydrocarbons by steam cracking is provided, which represents excellent elimination efficiency of coke while minimizing the amount of COx to be generated during coke gasification into COx, which causes plugging ...

The catalyst of the present invention is capable of efficiently decomposing hydrocarbons including hydrocarbons having 2 or more carbon atoms (C 2 or more hydrocarbons), is less expensive, and exhibits an excellent catalytic activity for decomposition and removal of hydrocarbons, in particular, an ...
A method and arrangement of catalyst handling steps is described for practicing a selective high temperature catalytic cracking of hydrocarbons which will take advantage of the low coke producing catalyst of high activity and selectivity. H Owen - US 被引量: 104发表: 1974年 Catalytic cracking of ...
it has now been discovered that high boiling hydrocarbons may be catalytically cracked and hydrogenated, or "hydro cracked," to obtain predominantly gasoline boiling range products of high octane number, by contacting the hydro carbons with hydrogen gas in the presence of a catalyst essentially compri...
Catalyst Deactivation 2001 A.A.Brillis., G.Manos., in Studies in Surface Science and Catalysis, 2001 1 INTRODUCTION Catalytic cracking of hydrocarbons has long reached technological maturity with only little benefit of a fundamental understanding and quantification of its elementary processes. Without ...
