Title: Systems and processes for conversion of ethylene feedstocks to hydrocarbon fuels

Abstract

Systems, processes, and catalysts are disclosed for obtaining fuels and fuel blends containing selected ratios of open-chain and closed-chain fuel-range hydrocarbons suitable for production of alternate fuels including gasolines, jet fuels, and diesel fuels. Fuel-range hydrocarbons may be derived from ethylene-containing feedstocks and ethanol-containing feedstocks.

  • Systems, processes, and catalysts are disclosed for obtaining fuel and fuel blends containing selected ratios of open-chain and closed-chain fuel-range hydrocarbons suitable for production of alternate fuels including gasolines, jet fuels, and diesel fuels. Fuel-range hydrocarbons may be derived from ethylene-containing feedstocks and ethanol-containing feedstocks.
  • Described is a method to make liquid chemicals, such as functional intermediates, solvents, and liquid fuels from biomass-derived cellulose. The method is cascading; the product stream from an upstream reaction can be used as the feedstock in the next downstream reaction. The method includes the steps of deconstructing cellulose to yield a product mixture comprising levulinic acid and formic acid, converting the levulinic acid to .gamma.-valerolactone, and converting the .gamma.-valerolactone to pentanoic acid. Alternatively, the .gamma.-valerolactone can be converted to a mixture of n-butenes. The pentanoic acid so formed can be further reacted to yield a host of valuable products.more » For example, the pentanoic acid can be decarboxylated yield 1-butene or ketonized to yield 5-nonanone. The 5-nonanone can be hydrodeoxygenated to yield nonane, or 5-nonanone can be reduced to yield 5-nonanol. The 5-nonanol can be dehydrated to yield nonene, which can be dimerized to yield a mixture of C.sub.9 and C.sub.18 olefins, which can be hydrogenated to yield a mixture of alkanes. Alternatively, the nonene may be isomerized to yield a mixture of branched olefins, which can be hydrogenated to yield a mixture of branched alkanes. The mixture of n-butenes formed from .gamma.-valerolactone can also be subjected to isomerization and oligomerization to yield olefins in the gasoline, jet and Diesel fuel ranges.« less

  • A multi-zone fluidized bed hydrocarbon conversion process and apparatus are disclosed for producing gas and distillable liquid products from heavy hydrocarbon feedstocks. The feedstock is introduced into an upper fluidized bed primary cracking zone maintained at temperature of 850/sup 0/-1400/sup 0/ F. for cracking reactions therein, and resulting tars and coke are deposited on and within a particulate carrier material contained therein. The carrier material containing said tars and coke descends successively through a stripping zone to remove tars and an interim controlled temperature zone for secondary cracking against an upflowing hot reducing gas, then descends into a lower fluidizedmore » bed gasification zone. The gasification zone is maintained at temperature of 1600/sup 0/-1900/sup 0/ F. by oxygen-containing gas and steam introduced therein to gasify the coke deposits and produce the reducing gas. The stripping zone contains a stationary packing material such as coarse particulate packing which is supported by a refractory apertured grid, or an ordered array of multiple structural members. The decoked hot particulate carrier material is recirculated upwardly through a transfer conduit to the upper fluidized bed primary cracking zone by a transport gas. Hydrocarbon liquid and gas products are withdrawn from the upper cracking zone.« less
