Embodiment Construction

[0023] It has surprisingly been found that the gaseous products obtained from the thermal processing of biomass can be converted in an efficient manner into a homogeneous product mixture useful as a product of value with a process in which oxidation of the gaseous products and condensation of the oxidation products takes place. In the process, a feedstock comprising gaseous products obtained from thermal processing of biomass is subjected to oxidation under conditions suitable for oxidation to produce an oxidation product, and the oxidation product is subjected to oxidation under conditions suitable for condensation. Condensation yields bio-oil. The quality of the bio-oil can be improved by treating the bio-oil vapor with an oxidizing agent (oxygen, hydrogen peroxide, ozone) and subjecting this oxidation product to condensation.

[0024] During the oxidation step, the organic molecule can be degraded whereby the oxidizing agent (oxidizing agent) forms the carboxylic acid funct...

Abstract

The present invention relates to a process for converting gaseous products, said process comprising the steps, where a feedstock comprising gaseous products obtained from thermal processing of biomass is subjected to oxidation in the presence of an oxidant, under conditions suitable for enacting said oxidation to yield an oxidation product, and subjecting the oxidation product to condensation in the presence of a basic catalyst to obtain bio-oil. The invention also relates to the use of bio-oil, obtainable by said process, as heating oil, as starting material in processes for producing fuels, fuel components, fine chemicals, chemical building-blocks, and solvents.

Description

field of invention [0001] The present invention relates to the conversion of gaseous products, especially feedstocks comprising gaseous products obtained from thermal processing of biomass, thereby modifying the composition of said feedstock, reducing the acid value and improving stability. The present invention also relates to subjecting gaseous products obtained from thermal processing of biomass to oxidation under conditions suitable for oxidation to produce oxidation products, and subjecting said products to condensation under conditions suitable for condensation to provide converted bio-oil . The invention also relates to the converted bio-oil obtainable by said method. Background of the invention [0002] Various methods and processes are used to obtain bio-oils with different properties and compositions. For example, bio-oil may be obtained from biomass using any suitable thermal processing, such as pyrolysis or the like. [0003] Pyrolysis is generally understood ...
