Abstract

The invention provides a hydrodeoxygenation method of bio-oil as well as a catalyst and a preparation method used thereby. The preparation method comprises: contacting a catalyst carrier dipped with active components with an oxygen-containing organic matter during the process of roasting the catalyst carrier dipped with the active components, completing the roasting to obtain an oxidized catalyst; vulcanizing the oxidized catalyst to obtain the product, wherein the active components comprise at least one or more of VIB group metals, one or more of VIII group metals, and one or more of VB group metals. By preprocessing the catalyst with the oxygen-containing organic matter, the selectivity of hydrogenated decarboxylation and decarbonylation reaction is increased; the sulfur fixation performance and thermal stability of the catalyst are improved.

Description

technical field [0001] The invention relates to the technical field of oil upgrading, in particular to a bio-oil hydrodeoxygenation method, a catalyst used therein and a preparation method thereof. Background technique [0002] With the increasing of heavy crude oil and environmental pollution, coal liquefied oil, Fischer-Tropsch synthetic oil and bio-oil (various animal and vegetable oils) have attracted the attention of researchers as ideal alternative energy sources, especially bio-oil, because of its It has the characteristics of less pollutant discharge and short cycle period, so it has become the focus of research. Compared with crude oil, the content of oxygenated compounds in bio-oil is higher, and the main types of oxygenated compounds include phenols, furans, esters and ketones. Due to the existence of a large number of oxygen-containing compounds, the oxygen content of bio-oil sometimes reaches as high as 50% by weight, resulting in bio-oil with low combustion ca...
