Embodiment 3

[0073] according to Figure 1a Fuel blends were prepared using the protocol shown in . The tall oil pitch (TOP) feed used in the experiment was analyzed, which contained the properties shown in Table 3, the animal fat (AF) feed used in the experiment was analyzed, which contained the properties shown in Table 4, and the The waste cooking oil (UCO) feed used in the experiments contained the properties shown in Table 5. The TCC reactor was operated at 460°C at atmospheric pressure with a WHSV setting of 0.3 l / h. The reactor was filled with TCC catalyst (silicon aluminum oxide, 3-5 mm) using glass beads at the top of the catalyst bed and quartz sand at the bottom. The obtained product was distilled using a batch still and a thin film distillation unit to obtain a diesel (160-370° C.) fraction and hydrotreated.

Abstract

A method of making a renewable fuel blend is disclosed. The process comprises catalytically cracking at least two feedstocks of different biological origin in a catalytic cracking unit and hydrotreating in a hydrotreating unit to form a fuel blend, measured according to ASTM D2425‑04 (2011), which The fuel blend has an aromatic content of 26 to 42 wt-% and a paraffin content of less than 53 wt-%. The fuel blend is formed by mixing together at least two feedstocks prior to subjecting them to catalytic cracking and hydrotreating, or by obtaining a first fuel component and at least one additional fuel component formed by mixing together said first fuel component and said at least one additional fuel component.

Description

technical field [0001] The present invention relates to a renewable fuel blend, and more particularly to a method for preparing the renewable fuel blend. Background technique [0002] Fossil or petroleum-based fuels can be replaced at least partially by fuels from biological resources (so-called co-feeds) including renewable raw materials such as fats and / or oils. Various types of fuels can be obtained from these triacylglycerol-containing feedstocks. One of these is biodiesel, which is defined as a monoalkyl ester of vegetable oil or animal fat. Biodiesel is produced by transesterifying oils or fats with alcohols, such as methanol, under mild conditions in the presence of a basic catalyst. Another class of products that can be obtained from lipid feedstocks are fuels with a composition simulating fossil diesel fuels, i.e. renewable diesel, which is produced from fats by hydrodeoxygenation reactions at elevated temperatures and pressures in the presence of catalysts. or o...
