Processes for catalytic conversion of lignin to liquid bio-fuels and novel bio-fuels

InactiveUS20080050792A1Increase productionAcceptable processing conditionBiofuelsSolid fuelsLiquid productLignin degradation
Processes for conversion of lignin to liquid products such as bio-fuels and fuel additives are disclosed and described. A process for conversion of a lignin material to bio-fuels can include subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin. The partially depolymerized lignin can then be subjected to a stabilization / partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product. Following partial hydrodeoxygenation, the partially hydrodeoxygenated product can be reacted in a hydroprocessing step to form a bio-fuel. Each of these reaction steps can be performed in single or multiple steps, depending on the design of the process. The production of an intermediate partially hydrodeoxygenation product and subsequent reaction thereof can significantly reduce or eliminate reactor plugging and catalyst coking. A variety of useful bio-fuels such as fuels, fuel additives, and the like, including gasoline and jet or rocket fuels are describe which can be readily produced from renewable lignin materials in an improved conversion process.

Process to obtain N-paraffins from vegetable oil

The process described by this invention involves the hydroconversion of vegetable oils appropriately selected for the production of N-paraffins, through hydrotreatment of a stream of vegetable hydrocarbon oils in and / or natural fats that may be used in a pure state or in a mixture with mineral hydrocarbon oil. This mixture flow is submitted to the process of hydrotreatment, obtaining as a result, a product flow with an elevated content of N-paraffins in the range of C10-C-13. This process provides an alternative to the usual process that uses a mineral hydrocarbon oil load (petroleum kerosene of paraffin base) to produce C10-C13 N-paraffins that are raw materials for the production of detergents (LAB), being, therefore, especially advantageous for use in situations where kerosene is a limiting factor for producing N-paraffins, resulting in a product of good quality with a reasonable gain in the production of N-paraffins.

Slurry dewatering and conversion of biosolids to a renewable fuel

ActiveUS20060096163A1Readily removed mechanicallyLow oxygenBio-organic fraction processingBiofuelsEmission standardSlurry
In the processes for treating municipal sewage and storm water containing biosolids to discharge standards, biosolids, even after dewatering, contain typically about 80% water bound in the dead cells of the biosolids, which gives biosolids a negative heating value. It can be incinerated only at the expense of purchased fuel. Biosolids are heated to a temperature at which their cell structure is destroyed and, preferably, at which carbon dioxide is split off to lower the oxygen content of the biosolids. The resulting char is not hydrophilic, and it can be efficiently dewatered and / or dried and is a viable renewable fuel. This renewable fuel can be supplemented by also charging conventional biomass (yard and crop waste, etc.) in the same or in parallel facilities. Similarly, non-renewable hydrophilic fuels can be so processed in conjunction with the processing of biosolids to further augment the energy supply.

The gasification uses a rotary kiln reactor and gas-gas cyclonic separation process to separate synthesis gas into purified hydrogen and purified carbon monoxide. Purified bulk carbon monoxide issued in metallurgical reduction, and purified bulk hydrogen as fuel for an emission-neutral hydrogen combined cycle (HCC) turbine power generation station. The carbochlorination is integrated with: a) the concurrent separation and purification of all metal-chlorides (metchlors) and capture of CO2 for passage to the carbon oxides management system; b) the direct reduction of metchlors to nanoscale metallurgical powders and / or to dendritically-shaped particles, including metchlor reduction for the ultrahigh-performance semiconductor metals of the III-V group; and, c) the reforming of metal-oxides with improved crystalline structure from metchlors.
