Abstract:
1. A process for producing distillate transportation fuels from municipal solid waste and triglycerides, which process comprising: a) feeding a municipal solid waste stream comprised of inorganic material, organic material, and water to a treatment zone wherein it is converted to a refuse derived fuel by removing at least a portion of the inorganic material; b) conducting at least a portion of the refuse derived fuel to a drying zone wherein the level of water is adjusted to a level that will produce a syngas having a H c) gasifying said refuse derived fuel to produce a syngas containing particulates and having a H d) treating said syngas to remove at least a portion of any particulates and at least one contaminant selected from the group consisting of H e) passing said cleaned syngas to a hydrogen recovery zone wherein hydrogen in excess of the amount needed for downstream Fischer-Tropsch synthesis is removed, thereby resulting in a hydrogen depleted syngas stream; f) passing at least a portion of said hydrogen depleted syngas stream to a Fischer-Tropsch synthesis zone wherein it is reacted under Fischer-Tropsch reaction conditions and in the presence of a Fischer-Tropsch catalyst to produce a vapor phase stream, a light liquid stream comprised predominantly of hydrocarbons the carbon range of about C5 to about C20, and a heavy liquid stream comprised predominantly of hydrocarbons in the carbon range of about C8 to about C20+; g) separating the vapor stream from the liquid streams; h) combining said light liquid stream with a triglyceride stream and passing the combined stream to a hydrotreating zone wherein it is subjected to hydrotreating conditions in the presence of a hydrotreating catalyst to produce a hydrotreated liquid hydrocarbon stream substantially free of oxygenates and unsaturated bonds; i) passing the hydrotreated stream to a hydroisomerization zone wherein it is subjected to hydroisomerization conditions in the presence of an hydroisomerization catalyst thereby resulting in an isomerized hydrotreated stream containing substantially more branched compounds than the hydrotreated stream before hydroisomerization; j) passing said heavy Fischer-Tropsch liquid stream from the synthesis zone to a hydrocracking zone wherein it is subjected to hydrocracking conditions in the presence of a hydrocracking catalyst, to produce a lower boiling product stream boiling primarily in the distillate boiling range; k) co-feeding the product streams from the hydrocracking zone and the hydroisomerization zone into a common fractionating zone, to produce at least two predetermined fractions one of which is a distillate boiling range transportation fuel stream.
