Definitions

  • porous inorganic solids that were originally found useful for catalytic processes included certain clays, aluminas, silica-aluminas and other silicas coprecipitated with magnesia, for example, and such solids are still extensively used in the industry. In general, all of these solids had pores that were not of uniform size, and most of the pore volume was in pores having diameters larger than about 30 Angstroms, with some of the pores as large or larger than 100 Angstroms.
  • Zeolite molecular sieves have been found to be highly effective as hydrocarbon conversion catalysts.
  • the conversion of gas oil to gasoline and distillate by catalytic cracking, the alkylation of benzene to ethylbenzene, the isomerization of xylenes and the disproportionation of toluene all involve molecules which are smaller in critical diameter than 1,3,5-triethylbenzene, and such molecules are occluded and acted upon by zeolite molecular sieves having an effective pore diameter of about 10 Angstroms.
  • a particularly interesting catalytic transformation which requires a molecular sieve catalyst is the reduction of the pour point of waxy distillates and residual hydrocarbon fractions.
  • Effective pour point reduction depends on the selective conversion of normal, high melting point paraffin molecules that have an effective critical diameter of about 5 Angstroms to substances of lower molecular weight that are easily separated from the low-pour product.
  • Effective catalytic dewaxing depends at least in part on the regularity of the pore size of the crystalline zeolites, which allows selective conversion of unwanted constituents.
  • Crystalline zeolite ZSM-11 is disclosed in U.S. Patent 3,709,979.
  • Example 9 of this patent taught fluid catalytic cracking at 875°F of a gas oil having a pour point of 100°F. High yields of olefins were obtained. The pour point of the product was reduced.
  • U.S. 4,332,670 taught catalytic dewaxing of middle distillates to produce a low pour fuel oil by using an intermediate pore size zeolite. There are no examples showing use of ZSM-11.
  • ZSM-11 which has been ignored experimentally by all prior workers in the lube oil and fuel oil area, is better for catalytic dewaxing than ZSM-5.
  • the present invention provides a process for catalytically dewaxing a wax containing hydrocarbon feedstock to produce a dewaxed oil which comprises contacting said stock at a temperature of 230 to 450°C, at a pressure of atmospheric to 14,000 kPa, and in the presence of hydrogen in a reaction zone with a catalyst comprising ZSM-11.
  • the present invention provides a process for producing lubricating oil base stock with high viscosity index comprising contacting a lubricating oil base feedstock containing waxy components with a dewaxing catalyst comprising 10 to 95 wt % ZSM-11 catalyst and 90 to 5 wt % refractory inorganic oxide binder in a catalytic dewaxing zone operated at 230 to 400°C, a pressure of atmospheric to 14,000 kPa, liquid hourly space velocity of 0.1 to 20 and wherein hydrogen is present and the ratio of hydrogen to hydrocarbon is 50 to 1,000 volumes of Ha at standard conditions per volume of liquid oil at standard conditions to produce a lubricating oil base stock with reduced wax content.
  • a dewaxing catalyst comprising 10 to 95 wt % ZSM-11 catalyst and 90 to 5 wt % refractory inorganic oxide binder in a catalytic dewaxing zone operated at 230 to 400°C, a pressure of atmospheric to 14,000 kPa, liquid
  • the present invention provides a process for catalytic dewaxing of a wax containing oil comprising contacting said oii in the presence of hydrogen at a temperature of 23D to 450°C, a hydrogen partial pressure of atmospheric to 14,000 kPa with a fixed bed of catalyst comprising ZSM-11 and a platinum group metal component to produce a catalytically dewaxed oil.
  • the silica to alumina mole ratio of ZSM-11, and other zeolites may be determined by conventional analysis. This ratio is meant to represent, as closely as possible, the ratio in the rigid anionic framework of the zeolite crystal and to exclude aluminum in the binder or in cationic or other form within the channels. Although zeolites with silica to alumina mole ratios of at least 10 are useful, it is preferred to use zeolites having higher ratios than about 12, preferably about 15 to 200. In addition, zeolites as otherwise characterized herein but which are substantially free of aluminum, that is zeolites having silica to alumina mole ratios of up to infinity, are found to be useful and even preferable in some instances.
  • Such "high silica” or “highly siliceous” zeolites tend to be hydrophobic and are intended to be included within this description. Also included within this definition are substantially pure silica analogues of the useful zeolites described herein, that is to say those zeolites having no measurable amount of aluminum (silica to alumina mole ratio of infinity) but which otherwise embody the characteristics disclosed.
  • the acid activity may be adjusted by crystallizing the ZSM-11 with only a little, or a lot, of aluminum, steaming the ZSM-11, acid extracting, or any other means conventionally used to adjust acid activity.
  • One method of measuring acid activity is to measure the cracking activity of a catalyst to obtain an alpha value or alpha activity.
  • a method of determining alpha activity is described in U.S. Patent 4,016,218.
  • the alpha test is a good measure of cracking activity, but not a measure of hydroisomerization activity.
  • 0ur ZSM-11 dewaxing process is believed to proceed by both cracking and hydroisomerization, so alpha activity provides some information about only one of the several reactions believed to occur during dewaxing.
  • An activated large pore zeolite, e.g., RENaX might have an alpha activity of over 10,000 and be a good FCC catalyst but do little or no dewaxing.
  • a good dewaxing catalyst e.g., Ni-ZSM-5, partially deactivated by coking, might have a low alpha activity and still do a good dewaxing job, so long as reactor temperatures were raised somewhat to adjust for the low alpha activity.
