Production process of novel environment friendly biological rubber aromatic oil

Abstract

The invention provides a novel process for producing environment-friendly biological rubber aromatic oil. The method takes lauraceae, apocynaceae, compositae, orchidaceae, flacourtiaceae, asclepiadaceae, plant edible extract oil and the like as raw materials to manufacture the aromatic oil. The method is characterized in that: (1) the raw materials are softened at a high temperature between 80 and 200 DEG C; (2) then the raw materials are steamed and fried for 60 minutes in a steaming-frying machine; (3) the raw materials are put into a cooling bucket and subjected to low-temperature treatment till the raw materials are at a suitable temperature between 30 and 40 DEG C; (4) squeezing and leaching are carried out through a squeezing machine, so as to squeeze out liquid; (5) the obtained liquid is subjected to high-temperature treatment at a temperature of 280 DEG C in a tower-type distillation machine; and (6) finally the liquid is refined and filtered in a filter, so as to obtain the aromatic oil. The process has the advantages of extensive raw material sources, no pollution, low cost and the like.

Description

technical field [0001] The invention relates to a method for refining reformed aromatic oil. Background technique [0002] The oil produced by the catalytic reforming reaction of naphtha is rich in aromatics and solvent naphtha, and also contains a small amount of olefins. For the reforming unit that produces aromatics and solvent oil, to produce qualified aromatics and solvent oil, it is faced with the problem of how to remove olefins in the produced oil. At present, there are two methods for industrially removing olefins from aromatic oils. One is a hydrorefining process, which uses platinum or palladium as a catalyst on alumina, and performs a "post-hydrogenation" process behind the reforming reactor to saturate olefins and achieve the purpose of removing olefins. Typical catalysts are CN85100760A, CN85100215A, CN1448474A patent report, the MH-508 noble metal catalyst that Shanxi coal institute develops is used now on the industry. Experiments show that the "post-hydro...

Problems solved by technology

The acid-treated clay mainly achieves the purpose of removing olefins in aromatic oil through adsorption or partial alkylation and olefin superposition condensation reaction. Although the refining method of clay has been widely used in industry, the effect of removing olefins Poor, and due to the high operating temperature, the colloid content in the produced oil becomes higher and the color deepens; at the same time, in the actual processing process, the clay has a short service life and a large amount, and the clay after deactivation cannot be regenerated, generally 2 to 3 It needs to be replaced with new white clay within a month, which frequently increases the loss of aromatics and workload, and a large amount of waste white clay needs to be dumped.
