Abstract

The invention relates to a method for preparing bio-oil by catalyzing and cracking microalgae with a supported Hangjin No.2 soil solid base catalyst. The method comprises the steps as follows: microalgae and supported Hangjin No.2 soil solid base catalyst are mixed at the weight ratio of (10:1)-(2:1) and then are placed in a thermal cracking reaction device, wherein nitrogen gas is taken as a carrier gas, the heating rate is 10-30 DEG C / min, and the temperature is raised to 350-600 DEG C; and gas generated during thermal cracking process is taken out of the reactor by the carrier gas, undergoes a three-stage cooling system of liquid nitrogen, dry ice and ice-water mixture, and then is collected to obtain liquid bio-oil. The invention further discloses the supported Hangjin No.2 soil solid base catalyst. According to the invention, on the basis that the supported compound solid base catalyst with high activity, high selectivity and low cost is synthesized, microalgae with high grease content is adopted and is transformed into bio-fuel oil through high-temperature catalytic cracking reaction, so that reaction temperature is lowered, green biological energy sources with excellent performances are obtained, and dual purposes of microalgae environmental management and high-value utilization of resources are achieved.

Description

technical field

[0001] The invention belongs to the technical field of bioenergy, in particular to a load-type Hangjin 2 # Soil solid alkali catalyst.

[0002] The present invention also relates to the use of the above load-type Hangjin 2 # The invention discloses a method for preparing biofuel oil by cracking microalgae with earth solid alkali catalyst. Background technique

[0003] The increasing depletion of global non-renewable energy and the global climate change caused by the greenhouse effect pose a serious threat to human survival and sustainable development. The development of green energy with high added value has become a research hotspot. Microalgae is the simplest photosynthetic organism. It is reported that more than 90% of the oxygen in the atmosphere is produced by microalgae. It has the advantages of high photosynthetic efficiency, fast growth and reproduction, strong environmental adaptability, and easy cultivation and amplification. It has been widely u...
