Embodiment 1～4

[0034] Examples 1-4 illustrate the effect of using the vegetable oil or / and animal oil catalytic conversion method provided by the present invention.

[0035] The catalyst (containing 10% by weight of zeolite beta, 20% by weight of ZSM-5 zeolite, and the balance as a carrier, all based on the total weight of the catalyst) was aged at 800°C with 100% steam for 10 hours, using a medium-sized test device, compounded The catalyst loading in the reactor was 60 kg.

Embodiment 1

[0036] Palm oil only enters riser reactor 1 among the embodiment 1;

Embodiment 2

[0037] In Example 2, 80% palm oil enters riser reactor 1, and 20% palm oil enters riser reactor 2.

Abstract

A catalytic conversion method of vegetable oil and fat or / and animal oil and fat is characterized in that the raw material of the vegetable oil and fat or / and the animal oil and fat is in contact with a modified Beta-zeolite-containing catalyst in a composite reactor to carry out the catalytic cracking reaction; the reaction product is separated from the spent catalyst; the separated spent catalyst returns to the reactor for reutilization after being stripped and regenerated by burning coke; and the separated reaction product is subjected to fractionation to obtain the target products including low-carbon olefin, gasoline, diesel oil and heavy oil. The method adopts the modified Beta-zeolite and the catalyst which contains zeolite with the MFI structure as the essential active composition, so as to achieve higher yield of the low-carbon olefin, particularly propylene. The total yield of C2-C4 olefins based on the carbon balance is over 45wt%, and the yield of propylene is as high as more than 24wt%.

Description

technical field [0001] The present invention relates to a method for catalytic conversion of bio-oil, more specifically, relates to a method for producing low-carbon olefins with high selectivity through catalytic conversion of bio-oil. Background technique [0002] The main components of vegetable oils and animal oils are triglyceride fatty acid lipids, which mainly contain carbon, hydrogen, and oxygen elements, and the content of sulfur and nitrogen is very small. It is a green and renewable resource. With the application of transgenic technology, vegetable oil , The output of animal fat increased rapidly. Early studies mainly used vegetable oil and animal oil to pyrolyze to produce fuel, but the selectivity of the target product was low. However, by converting vegetable oil and animal oil into fuel through catalytic cracking, the selectivity of the target product will be improved. [0003] US2006 / 0151357A1 discloses a method for treating organic waste, which converts or...
