Abstract
Aspects of the present disclosure generally relate to processes and apparatus for producing fuels and fuel compositions. In an aspect, a process for converting a carbon-containing feedstock is provided. The process includes drying a carbon-containing feedstock comprising biomass to form a terpene stream and a dried carbon-containing material, and hydrotreating the terpene stream to form a first hydrocarbon stream. The process further includes gasifying the dried carbon-containing material to form syngas, converting the syngas to a second hydrocarbon stream, and introducing the first hydrocarbon stream and the second hydrocarbon stream to form a fuel composition.
Claims16
A process, comprising:
- drying a carbon-containing feedstock comprising biomass to form a terpene stream and a dried carbon-containing material using an integrated apparatus comprising a drying unit coupled to a gasification unit and coupled to a hydrotreatment unit, wherein the drying unit is coupled to the gasification unit via a first material transfer line and to the hydrotreatment unit via a second material transfer line, and wherein the dried carbon-containing material is directly transferred from the drying unit to the gasification unit through the first material transfer line;
- hydrotreating the terpene stream to form a first hydrocarbon stream;
- gasifying the dried carbon-containing material to form a syngas;
- converting the syngas to a second hydrocarbon stream;
- and
- combining the first hydrocarbon stream and the second hydrocarbon stream in a collection unit coupled to both the hydrotreatment unit and a syngas conversion unit to form a fuel composition, wherein the collection unit comprises a first inlet line receiving the first hydrocarbon stream from the hydrotreatment unit and a second inlet line receiving the second hydrocarbon stream from the syngas conversion unit, and wherein the collection unit is configured to blend the first and second hydrocarbon streams.
A process, comprising:
- converting biomass to a terpene stream and a dried carbon-containing material using an integrated apparatus comprising a coupling between processing units;
- introducing the terpene stream with hydrogen and a hydrotreatment catalyst to form a first hydrocarbon stream;
- introducing the dried carbon-containing material with a gasification agent to form a syngas, wherein the dried carbon-containing material is transferred from a drying unit to a gasification unit through a material transfer line;
- converting at least a portion of the syngas to a second hydrocarbon stream comprising:
- introducing the syngas to a Fischer-Tropsch catalyst to form the second hydrocarbon stream;
- or
- introducing the syngas to a microorganism to form ethanol and oligomerizing ethanol to form the second hydrocarbon stream;
- and
- combining the first hydrocarbon stream to the second hydrocarbon stream in a shared collection unit to form a fuel composition, wherein the shared collection unit is positioned to receive streams from multiple processing units via separate inlet lines and is configured to blend the streams.
