摘要:
The present invention relates to a liquid phase additive comprising an alkyl nitrate; a petroleum sulphonates; an aliphatic, aromatic, cyclohexylamines or hetroalkylated lower amines; a hindered phenol based compounds; a phosphate esters and an aliphatic alcohols for use in delayed coking process with decreased coke yield and increased yield of liquid and/or gaseous product and a process for preparing the liquid phase additive. The present invention also relates to a process for thermal cracking of petroleum residue producing petroleum coke and lighter hydrocarbon products by using liquid phase additive.
摘要:
A process for the preparation of a CO oxidation promoter which comprises in preparing a slurry of colloidal silica/clay and a binder with peptised pseudoboehmite. The slurry is then subjected to the step of spray drying to obtain microspheres. The microspheres are calcined and then impregnated with platinum.
摘要:
The present invention is directed to novel thermal cracking additive compositions for reduction of coke yield in Delayed Coking process and method for preparing the same. The present invention also provides that the thermal cracking additive compositions of the present invention are in micron-size and nano-size. Further, the present invention provides a process of thermal cracking of heavy petroleum residue used in petroleum refineries using Delayed Coking process to produce petroleum coke and lighter hydrocarbon products with decreased coke yield and increased yield of liquid and/or gaseous products.
摘要:
A process for preparation of fluidized catalytic cracking (FCC) catalyst, comprising silicon stabilized large crystallite sized synthetic faujasite zeolite, aluminum depleted and normal kaolin clay, alumina and silica. The cracking catalyst is highly active and selective for bottom upgradation, it produces less coke and higher gasoline and total cycle oil. (TCO) and possesses improved metal tolerance properties when evaluated and compared with a commercial catalyst under conditions of a typical FCC unit in a petroleum refinery.
摘要:
The invention relates to a process for catalytic cracking of petroleum based feed stocks to produce high yield of LPG and light olefins with C 3 and C 4 in presence of solid acidic catalyst and high pore size acidic components in a fluidized bed reactor The reactor operates in the range of 40-120 hr -1 weight hourly space velocity, 15-25 catalyst to oil ratio and riser temperature of 520-600°C.
