Embodiment 1

[0078] In this embodiment, straw is used as biomass raw material, the processing capacity is 12tpd, and the production capacity is 10bpd synthetic oil. All equipments are arranged and installed in one container, please refer to Figure 4 . The Fischer-Tropsch synthesis reactor 15 adopts a microchannel reactor, the Fischer-Tropsch synthesis catalyst adopts a bifunctional catalyst with cracking effect, and the Fischer-Tropsch synthesis oil product does not contain wax, so the wax oil processing unit 105 is not used. All light hydrocarbon tail gas is used for power generation to supply energy for the system. The specific process parameters are shown in Table 1.

Embodiment 2

[0080] In this embodiment, sapwood is used as biomass raw material, the processing capacity is 18tpd, and the production capacity is 30bpd synthetic oil. The Fischer-Tropsch synthesis reactor 15 adopts a microchannel reactor, the Fischer-Tropsch synthesis catalyst adopts a bifunctional catalyst with cracking effect, and the Fischer-Tropsch synthesis oil product does not contain wax, so the wax oil processing unit 105 is not used. All light hydrocarbon tail gas is used for power generation to supply energy for the system. The specific process parameters are shown in Table 1.

Embodiment 3

[0082] In this embodiment, straw briquette fuel is used as biomass raw material, the processing capacity is 45tpd, and the production capacity is 50bpd. The Fischer-Tropsch synthesis reactor 15 is a tubular fixed-bed reactor, and the catalyst is an iron-based catalyst. The oil produced by the Fischer-Tropsch synthesis contains wax oil, so a wax oil processing unit 105 is required. Half of the light hydrocarbon tail gas is recycled to the Fischer-Tropsch synthesis reactor, and the other half is used to generate electricity for the system. The specific process parameters are shown in Table 1.

Abstract

The invention discloses a method and a system for preparing synthetic oil by using miniaturized biomass based on a mobile platform. According to the method, a biomass raw material gasifying unit, a synthesis gas purifying converting unit and a fischer-tropsch synthesis unit which are successively connected with each other are integrally arranged on the mobile platform, the mobile platform is flexibly transported to a biomass distribution site or a preset processing place according to the requirement and then the synthetic oil production process is directly performed on the mobile platform. The system comprises the biomass raw material gasifying unit, the synthesis gas purifying converting unit and the fischer-tropsch synthesis unit which are integrally arranged on the mobile platform, wherein the biomass raw material gasifying unit is used for gasifying the biomass; the synthesis gas purifying converting unit is used for purifying and converting the rough synthesis gas; the fischer-tropsch synthesis unit is used for performing fischer-tropsch synthesis on the synthesis gas after the synthesis gas is purified and converted. The system is moved through the mobile platform, the production is performed on the mobile platform and the system has the characteristics of microminiaturization, mobility, economical and feasible effect, flexibility and convenience.

Description

technical field [0001] The invention relates to a system for producing synthetic oil from biomass, in particular to a method and system for producing synthetic oil from biomass based on a miniaturized mobile platform. Background technique [0002] With the decrease of traditional fossil energy and the increasing degree of environmental pollution, the development of renewable and environmentally friendly energy has attracted more and more attention from human society. Among them, as an important renewable and environmentally friendly energy, biomass can not only make an important contribution to improving the world's primary energy structure and reducing the demand for fossil energy, but also reduce greenhouse gas emissions, ensure energy supply security, and improve trade. balance, promoting rural development and improving the way urban waste is disposed of. [0003] Biomass to synthetic oil technology (BTL) is one of the most potential biomass energy conversion technologie...
