Fluidized catalytic cracking of hydrocarbons in risers, stripping vapors, cyclonesdoi:US4988430 AThe use of lift gas for FCC risers is improved by the direct use of reactor vapors as the source of the lift gas. Reactor vapors recovered primarily from the stripping section of an FCC reactor/...
The present invention relates to a process for the conversion of hydrocarbon streams with 95% true boiling point less than 400° C. to very high yield of liquefied petroleum gas in the range of 45-65 wt % of feed and high octane gasoline, the said proces
Method for preventing erosion in fluidized catalytic cracking of hydrocarbonsThe present invention is directed to catalytic cracking of the type which has come to be-known as"fluid catalyst cracking. 'In fluid catalyst cracking the catalyst is carried through an-elongated reactor in suspension -in'a...
A composition for passivating metal contaminants in catalytic cracking of hydrocarbons includes a non-layered, ultra-large pore crystalline material with at least one peak at a position greater than about 18 Angstrom Units d-spacing with a relative intensity of 100, and a benzene adsorption capacity...
METHOD AND DEVICE FOR FLUID CATALYTIC CRACKING OF HYDROCARBON FEEDSTOCK The invention concerns a method for fluid catalytic cracking of hydrocarbons. A considerable part of the hydrocarbons is pulverised and contacted with the catalyst in a specific contacting zone, which consists: of a mixing chamber...
Fluid catalytic cracking is one important part of the petroleum refining processes. The heavy oil is reacted in a lifting tube having a temperature of about 500 °C in the presence of a molecular sieve catalyst. The hydrocarbons of the born can be separated into cracking gas, high octane gas...
(A5). It was assumed that the water and the hydrocarbons are immiscible. In order to calculate the heat of vaporization of the hydrocarbon mixture (Lcond) the following procedure was applied. First, the mass and molar fraction of the condensed mixture should be determined by(A7)Yi=m˙i∑...
A process and an apparatus for the fluidized catalytic cracking of hydrocarbons are disclosed. A small vent conduit extends upward out of the flow diversio... CW Strother 被引量: 2发表: 1983年 Device for solid particles treatment in a fluidized bed and use therof Equipment for stripping or...
Catalyst containing entrained and sorbed hydrocarbons pass from the bottom of a reactor vessel into the small diameter rejection vessel that provides a hydrocarbon rejection zone and uses a fresh stripping medium to maintain a dense fluidized bed from which entrained hydrocarbons are quickly disengaged ...
Notwithstanding the well-established SMR technology, thermochemical conversion techniques such as auto-thermal reforming, partial oxidation, and plasma catalytic reforming were developed and applied by researchers for efficient hydrogen generation [23,26,27,28]. However, most of the abovementioned ...
