Abstract: A crude oil processing plant that comprises a Fischer-Tropsch reactor is disclosed. The crude oil processing plant comprises a crude oil processing section and a hydrogen production section. The hydrogen production section is coupled to a hydrocracker in the crude oil processing section to deliver a high purity hydrogen stream. The Fischer-Tropsch reactor receives a syngas stream from the hydrogen production section and produces a hydrocarbon stream. When light crude oil is processed, the hydrocracker typically has excess capacities to upgrade the hydrocarbon stream from the Fischer-Tropsch reactor.

Abstract: Systems and methods for generating higher alcohols from synthesis gas produced from carbonaceous materials are described, which can include a reactor configured to produce an alcohol stream and CO2 from a syngas feed. The alcohol stream can be separated in one or more downstream separators to produce a net reactor product and a methanol stream that can recycled into the reactor. The net reactor product preferably comprises higher-order alcohols such as ethanol, propanol, and butanol.
