Definitions
- distillate fraction from (d) subjecting the distillate fraction from (d) to thermal cracking in the presence of steam thereby converting at least a portion of the liquid phase to normally gaseous hydrocarbons and recovering the normally gaseous olefins from the pyrolysis zone effluent.
- the present invention relates to a process for the production of normally gaseous olefins from atmospheric petroleum residue feedstocks.
- the residue from the atmospheric distillation unit hereinafter to be referred to as an atmospheric petroleum residue feedstock, is composed of fractions boiling under atmospheric pressure at a temperature greater than 300C. This residue may either be used directly as fuel oil or as feedstock to a distillation unit operating at reduced pressure.
- the distillate from the distillation unit operating at reduced pressure otherwise known as a vacuum distillate, may be used as catalytic cracker feedstock or used in lubricating oil manufacture whilst the residue, hereinafter to be referred to as the vacuum residue, may be blended for use as fuel oil.
- a process for the production of normally gaseous olefins from an atmospheric petroleum residue feedstock which process comprises contacting the atmospheric petroleum residue feedstock in a hydrogenation Zone with a hydrogenation catalyst and hydrogen under conditions which effect hydrogenation of aromatic hydrocarbons, separating from the resulting hydrogenated atmospheric petroleum residue feedstock a gaseous phase containing hydrogen and a liquid phase containing hydrocarbons. recycling at least a portion of said gaseous phase to said hydrogenation zone.
- Distillate fraction withinthe context of the present application means that fraction of the liquid phase containing hydrocarbons having a boiling range below 650C at atmospheric pressure and residue fraction that fraction having a boiling range above that of the distillate fraction.
- normally gaseous olefins within the context of the present application is intended to mean olefins which exist in the form of gases at normal temperature and pressure.
- the whole of the liquid phase containing hydrocarbons resulting from the hydrogenation of the atmospheric petroleum residue feedstock may, after separation of a gaseous phase containing hydrogen, be fed in the presence of steam directly to the pyrolysis zone wherein unvapourised feedstock is removed as a residue fraction-in a separation zone prior to entry of the vapourised distillate fraction into that region of the pyrolysis zone maintained under conditions which effect thermal cracking.
- the temperature of the liquid phase containing hydrocarbons/steam mixture fed to the pyrolysis zone is preferably regulated to maximise the proportion of hydrocarbons in the distillate fraction without promoting incipient thermal cracking of the mixture.
- Thermal cracking within the context of this application is intended to include steam cracking but not catalytic cracking.
- Hydrogenation of the petroleum residue feedstock not only achieves hydrogenation of aromatics thereby leading to a reduction in boiling point of the compounds involvedand an increase in the proportion of the feedstock available for thermal cracking to gaseous olefins but also effects desulphurisation of the feedstock, leads to substantially increased yields of useful olefins for a given quantity of feedstock and results in a reduction of coke laydown in the cracking coil and of tar deposits in transfer lines and heat exchangers.
- a typical nickel/tungsten/silica/alumina catalyst may have the composition 1-6 per cent by weight of nickel and 9-27 per cent by weight of tungsten, with a silica to alumina ratio in the range 90:10 to 25:75 but compositions outside this range are also effective.
- Cobalt- /molybdnum/alumina catalysts produced commercially may contain up to 0.5% silica. I
- the catalyst may conveniently be prepared by impregnating the support with an aqueous solution of a salt of each of the metals, either consecutively or simultaneously.
- nickel may be added in the form of nickel nitrate, tungsten as ammonium metatungstate, cobalt as cobalt nitrate, acetate etc. and molybdenum as ammonium molybdate. It will usually be found convenient to impregnate the support first with the salt of the metal which is to be present in the highest concentration in the finished catalyst though this is not essential.
- Other methods of preparing the catalyst include precipitating the metals on the support from a solution of their salts and co-precipitation of the metals with the hydrated support material.
- the catalysts be activated before use in the reaction by contact with a stream of hydrogen at a temperature in the range 100 to 800C, more preferably 300 to 600C for a period of 1 minute to 24 hours.
- the catalyst may also be used in the sulphided form.
- the sulphided form of the catalyst may conveniently be prepared by passing hydrogen through liquid tetrahydrothiophene and then'over the catalyst maintained at a temperature in the range 100C to 800C, preferably 300C to 600C for a period of l minute to 24 hours.
- the hydrogenation temperature may be in the range 50 to 500C, preferably 300 to 400C and the pressure may be in the range 50 to 500 psig. preferably 200 to 3000 psig.
- Hydrogenation may be carried out in a singlestage or in a series of two or more operations using the same or different catalysts.
- Thermal cracking of the distillate fraction in the presence of steam may suitably be effected at a steam to hydrocarbon weight ratio of about 0.5:1 to 2.0: l in a heated zone, preferably a tube, at a maximum temperature in the range 700 to 1000C with a residence time in the temperature range between 0.01 and 5 seconds, preferably 0.1 to 2.0 seconds.
- the products may be rapidly cooled in a heat exchange system and separated and purified by conventional means.
- olefins e.g. ethylene and propylene are used as feedstocks for the production of a wide variety of chemical and polymeric products.
- iEXAMPLE 1 A 300 g sample of the Kuwait atmospheric residue used in the comparison test was hydrogenated in a 1 litre rocking autoclave at 370C under 2500 psig. of hydrogen during 24 hours using g of a cobalt oxide/' molybdenum oxide/alumina catalyst.
- the catalyst containing 3.9 per cent weight cobalt, 19.7 per cent weight molybdenum, and less than 0.1 per cent weight silica, and after calcination in air at 550C for 2 hours was activated in a stream of hydrogen at 400C for 24 hours.
- the recovered hydrogenated'atmospheric residue had a hydrogen to carbon atomic ratio of 1.86 and a sulphur content of 0.14 per cent weight.
- the vacuum distillate was steam cracked under the same conditions as were used in the comparison test.
- the ethylene and propylene yields were 24 and 1 1 per cent weight on feed respectively with a total conversion to cracked gas of 57 per cent.
- EXAMPLE 2 A 300 g sample of the Kuwait atmospheric residue used in the comparison test was hydrogenated in a 1 litre rocking autoclave at 370C under 2500 psig. of hydrogen during 24 hours using 54.5 g. of a nickel oxide/- tungsten oxide/silica/alumina catalyst.
- the catalyst contained 4.9 per cent weight nickel, 15.9 per cent weight tungsten and the silica to alumina ratio was 3: 1.
- the catalyst was again first calcined in air at 550C for 2 hours and then immediately before use it was activated at 400C in a stream of hydrogen for 24 hours.
- the recovered hydrogenated atmospheric residue had a hydrogen to carbon atomic ratio of 1.79 and a sulphur content of 0.28 per cent weight.
- a process for the production of normally gaseous olefins from an atmospheric petroleum residue feedstock which process comprises the steps of:
- a hydrogenation catalyst selected from nickel/molybdenum/alumina, cobalt- /tungsten/alumina, nickel/tungsten/alumina, cobalt/molybdenum/alumina. nickel/cobalt/molybdenum/alumina. cobalt/molybdenum/- silica/alumina. nickel/molybdenum/silica/alumina,
- thermal cracking of the distillate fraction in the presence of steam is effected at a steam to hydrocarbon weight ratio of 0.5:1 to 2.021 in a heated zone at a maximum temperature in the range 700 to 1,000C with a residence time in this range between 0.01 and 5 seconds.
