Definitions
- the steam cracked gasoline may be given a mild hydrogenation treatment to remove part of the gumforming constituents before a distillation stage and thereafter a narrow cut, obtained by distillation, fed to a second hydrogenation over a nickel catalyst for the removal of substantially all of the remaining gum-forming constituents.
- a major constituent of the gum-forming material will usually be in the form of dienes; these, under the hydrogenating conditions for the removal of gum-forming materials, will be mainly converted to mono-olefins.
- hydrogenation may be carried out using a gas consisting of hydrogen together with inert constituents.
- the gas contains at least mol percent of hydrogen, the proportion suitably lying within the range 2590 mol percent of hydrogen.
- a preferred gas is a platforrner tail gas.
- a gas is employed containing 70 mol percent of hydrogen.
- a typical gas will consist of 70 mol percent of hydrogen and mol percent of methane.
- Other suitable gases are steam cracker tail gas, catalytic cracker tail gas and tail gas derived from the dehydrogenation of hydrocarbons.
- the olefin-removing stage is carried out in the presence of a catalyst comprising cobalt oxide and molybdenum oxides on a support.
- a catalyst comprising cobalt oxide and molybdenum oxides on a support.
- the support is alumina.
- the catalyst contains 1 to 10% Wt. of cobalt oxide, expressed as C00 and 5 to wt. of molybdenum oxide, expressed as M00
- the catalyst comprising cobalt oxide and molybdenum oxide is preferably used within the following ranges:
- Pressure 100 to 1000 p.s.i.g. Temperature 150 to 480 C. Space velocity 0.5 to 8.0 v./v./hr. Gas recycle rate 500 to 8000 s.c.f./b.
- the conditions of operation of the olefin-removing stage are selective to favour the desulphurisation of the feedstock which is fed to this stage.
- the product being mainly a mixture of parafiins and aromatics, is very suitable for further treatment by solvent extraction, for example, by means of dior tri-ethylene glycols, for the recovery of an extract of high aromatic content.
- the stabilised gasoline product had the following characteristics: Spccific gravity 60/60 F 0.817.
- Type Nickel and cobalt hydroxides supported on aluminium silicate.
- Reaction pressure 445 lbs./s in. gauge.
- Table 2 o q Mean catalyst bed temperature--- 223 F. 1 Space velocity t 1.75 v./v./hr.
- Recycle gas hydrogen content (H 3 free) 92-95 percent mol.
- Hydrogen consumption was initially 160 s.c.f./b.; this value declined rapidly to zero at 336 hours on stream. During this run the pressure differential across the catalyst bed increased rapidly until the termination of the run at 336 hours. On examination of the reactor it was found that substantial blockage had occurred in the pre-heating zone prior to the catalyst bed. The catalyst was coated with polymer which probably accounted for the nil hydrogen consumption immediately prior to shut-down.
