Abstract

A method for producing a hydrocarbon from a biological material, the hydrocarbon and a fuel, the method comprises a reaction step, a separation step, a distillation step and a cycle step; in the reaction step, a feed material and hydrocarbon are fed into a reactor for hydrogenation saturation reaction, deoxygenation reaction, and alkane isomerization in the presence of a catalyst to produce a reaction product comprising a liquid hydrocarbon component, a gas component and water; in the separation step, the liquid hydrocarbon component, the gas component and the water are separated; in the distillation step, the liquid hydrocarbon component from the separation step is distilled to collect a target hydrocarbon product; in the cycle step, the liquid hydrocarbon component from the separation step or the target hydrocarbon product from the distillation step is cycled, and the cycled liquid hydrocarbon component or target hydrocarbon product is used in the reaction step, wherein in the reaction step, the catalyst is a supported catalyst of a Group VIII metal supported on a ten-membered-ring one-dimensional pore molecular sieve. The method dilutes the feed material by the cycle step, alleviates reaction heat release and reduces the influence of the reaction heat effect on the catalyst.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for producing hydrocarbons using biological materials, hydrocarbons and fuels thereof. Background technique [0002] The reduction of primary energy such as oil and coal has brought about the problem of energy shortage. In recent years, the price of crude oil and coal has continued to rise, and the price of fuel has also risen accordingly. At the same time, because both petroleum and coal contain elements such as nitrogen and sulfur, toxic gases that are harmful to the environment will inevitably be produced during their conversion and product use. Based on this, some countries have introduced relevant restrictive policies for the use of fossil energy products. The above factors have prompted researchers to start looking for new energy sources that can replace fossil energy sources. There are many carbon-containing renewable biomaterials in nature. After hydrogenatio...
