Abstract

The invention relates to the technical field of biological engineering and preparation of clean energy sources, in particular to a preparation method of microalgae biodiesel with high caloric heat. The preparation method comprises the following steps of using chlorella as a raw material to prepare chlorella grease; esterifying the chlorella grease, and centrifugally delaminating, so as to obtain alower biodiesel crude product; continuing to distill, so as to obtain the microalgae biodiesel with high caloric heat. The preparation method has the advantages that the microalgae is promoted to quickly grow under the conditions of relatively moderate light radiation and light quality, highly-concentrated soil extracting solution as culture liquid, proper temperature and the like, so that the diesel production efficiency is improved; the chlorella is single cell pyrenoid chlorella, the pyrenoid chlorella has stable suitability to the environment, the rich nitrogen and phosphor elements and the inorganic elements in biogas slurry can be absorbed, the function of promoting accumulation of chlorella cell grease is realized, the production efficiency of the biodiesel is improved, the maximumcontent of grease is obtained, the content of carbon in the grease is increased, and the purpose of improving the caloric heat of the biodiesel is realized.

Description

technical field [0001] The invention relates to the technical fields of bioengineering and clean energy preparation, in particular to a method for preparing high calorific value microalgae biodiesel. Background technique [0002] With the rapid development of the world economy, fossil fuels can no longer meet the needs of world economic development. Especially in recent years, the international oil price has soared sharply, which has an increasing impact on the economies of various countries. Biodiesel is an excellent renewable new energy. As a renewable energy project that is being actively promoted in the world, it will become the main energy source of human beings in the 21st century together with clean nuclear energy, wind energy, and photovoltaic power generation. [0003] The most common way to produce biodiesel is esterification, which is the process of adding a certain amount of methanol to vegetable oil, heating it to a certain temperature, and reacting with a cata...
