CONTINUOUS METHOD AND DEVICE FOR PREPARING HYDROCARBON FROM BIOLOGICAL ORIGINS USING HYDROTALCITES AS CATALYST

摘要

PURPOSE: Continuous method and apparatus for preparing hydrocarbon using biological originated lipid and hydrotalcite are provided to produce the hydrocarbon without using hydrogen, and to reduce the operational costs. CONSTITUTION: A continuous method for preparing hydrocarbon using biological originated lipid and hydrotalcite comprises the following steps: supplying raw materials selected from triglyceride, fatty acid, or fatty acid derivative into a first reactor(2); contacting the raw material in the first reactor with a hydrotalcite catalyst to obtain the hydrocarbon; recycling the used hydrotalcite after the termination of the reaction inside the first reactor; supplying the raw materials into a second reactor(3) during the recycling process of the hydrotalcite; contacting the raw materials in the second reactor with the hydrotalcite catalyst to obtain the hydrocarbon; and recycling the used hydrotalcite after the termination of the reaction inside the second reactor, and repeating previous steps.
