Embodiment 1
[0110] Example 1: Provides a first mixture component containing renewable components according to a preferred embodiment of the present invention
[0111] Three different renewable crude oils (Oil A, Oil B, and Oil C) use figure 1 The trial process in is produced from birch and pine. The analysis of the wood chips received is shown in Table 1 below.
[0112] Table 1: Composition of dry ash-free carbonaceous materials.
[0113]
[0114] Feed preparation
[0115] Wood chips are comminuted into wood flour in a hammer mill system and mixed with circulating water (including dissolved salts and water soluble organics), circulating oil, catalyst to produce a homogeneous and pumpable feed mixture. Potassium carbonate was used as a catalyst and sodium hydroxide was used to adjust the pH. Try to keep the potassium concentration constant during the run by measuring the potassium concentration in the aqueous phase and based on that determine the catalyst concentration that needs t...
Embodiment 2
[0140] Example 2: Providing a First Blend Component Containing Renewable Components by Upgrading Renewable Crude Oil
[0141] Renewable crude oils (Oil A, Oil B and Oil C) were produced from pine wood as described in Example 1, partially upgraded by hydrotreating, as image 3 shown.
[0142] The process was carried out in a continuous experimental process unit using a downflow tubular reactor. Three separate heating zones are used to ensure an isothermal distribution in the catalyst bed. Thus, the reactor is divided into three sections comprising a preheating zone, a catalyst bed (isothermal zone) and an outlet zone. The reactor is filled with 25% to 50% degradation catalyst with silicon carbide inert material. A commercially available NiMo-S catalyst was used.
[0143] First, the catalyst bed was dried in a nitrogen atmosphere at a temperature range of 100°C to 130°C, and then activated by a presulfurization process using Sulfur-spiked diesel containing 2.5% by weight of ...
Embodiment 3
[0149] Example 3: Providing a First Blend Component Comprising Renewable Components by Further Upgrading Partially Upgraded Oil
[0150] Such as image 3 As indicated, the partially upgraded oil product as described in Example 2 was subjected to a further hydrotreatment stage.
[0151] The process was carried out in a continuous experimental process unit using a downflow tubular reactor. Three separate heating zones are used to ensure an isothermal distribution in the catalyst bed. Thus, the reactor is divided into three sections comprising a preheating zone, a catalyst bed (isothermal zone) and an outlet zone. The reactor was filled with 50% degradation catalyst with silicon carbide inert material. A commercially available NiMo-S catalyst was used.
[0152] The catalyst bed was first dried in a nitrogen atmosphere at a temperature range of 100°C to 130°C and then activated by a presulfidation process using sulfurized diesel oil containing 2.5% by weight of dimethyl disulf...
