Title: Production of diesel fuel from light olefins

Abstract

Mobile Research and Development Corporation has developed a catalytic process for converting light olefinic compounds to high quality gasoline and distillate. The process has been named Mobil Olefin to Gasoline and Distillate (MOGD) Process. Based on the Mobile zeolite catalyst ZSM-5, light olefins can be shape selectively oligomerized to higher molecular weight iso-olefins. In the gasoline boiling range, these olefins have a high octane number and for the diesel fuel range product a high cetane number and low pour point following hydrogenation. Through normally designed to process propylene or butylene, MOGD is applicable to a wide range of feed streams ranging from ethylene to 400/sup 0/F endpoint olefinic naphtha. The process has been tested using commercially-produced catalyst in refinery scale equipment.

  • Mobil Research and Development Corporation has developed a catalytic process for converting light olefinic compounds to high quality gasoline and distillate. The process has been named Mobil Olefin to Gasoline and Distillate (MOGD) Process. This process is based on a synthetic zeolite catalyst which shapes selectively oligomerized light olefins to higher molecular weight iso-olefins. In the gasoline boiling range, these olefins have a high octane number and for the diesel fuel range product a high cetane number following hydrogenation. The process is highly flexible, and a commercial plant can be designed to produce distillate/gasoline ratios of 0/100 to 90/10 dependingmore » on market requirements. Though normally designed to process propylene or butylene, MOGD is applicable to a wide range of feed streams ranging from ethylene to 400/sup 0/F end point olefinic naphtha. The process has been tested using commercially-produced catalyst in refinery scale equipment.« less
  • Mobil Research and Development Corporation has developed a fluid-bed process for the production of olefins from methanol. The olefins can be converted to gasoline, distillate, and/or aviation fuels by commercially available technologies. The process is based on the ZSM-5 family of shape selective zeolite catalysts. Initial development in fixed and fluid-bed micro-units gave total olefins selectivities exceeding 75 wt% of hydrocarbons with complete methanol conversion. Scale-up to a 4 BPD fluid-bed pilot plant was successful in maintaining high olefin yield. The process has recently been scaled up in a 100 BPD demonstration plant in Germany.
  • Exhaust emissions from a diesel passenger car were characterized and measured to examine the effect of ambient temperature on emissions performance. The vehicle was tested at three temperatures on a chassis dynamometer located within a coal cell. Three driving cycles and three fuels of varying quality were used. The effort included measurements of regulated exhaust gases and particles, particulate organic fractions and their molecular-weight distributions, particulate fractions under 2 microns in diameter, trace metal contents, and fuel economy. Results indicate that reductions in ambient temperature had little effect on emissions or fuel economy in this study. In some cases, statisticallymore » significant increases in NO/subX/ emissions were measured with decreases in ambient test temperature. Other differences related to temperature effects occurred more frequently with the lower quality fuels.« less
  • In many countries, cetane number and distillation properties of diesel fuel have been changing, thus affecting the performance of diesel engines. This paper describes investigations made on the effect of diesel fuel quality on white smoke (one of the important emissions of diesel engines). The result of simple laboratory tests simulating high altitude conditions plus field tests using three types of diesel engines supplied with various types of diesel fuels is given. It was found that white smoke appearing tendency correlated best with cetane number and the 90 percent distillation point of the fuel. The field test performed at highmore » altitude correlated well with the simple laboratory tests.« less
