Abstract

The invention discloses biodiesel prepared by performing ester exchange reaction on the Idesia polycarpa var.vestita Diels oil and low-carbon alcohol under catalysis of solid acid serving as a catalyst. A process method and condition of the biodiesel comprise the following steps of: hydrating to degum; performing alkali refining to deacidify; decoloring; performing reaction under the catalysis ofthe solid acid; and separating. The Idesia polycarpa var.vestita Diels with high yield and good oil quality is developed and utilized, so that the raw material cost is effectively reduced. In particular, when the yield of the Idesia polycarpa var.vestita Diels in the initial period cannot reach the scale, the Idesia polycarpa var.vestita Diels oil is utilized so as to contribute to development ofthe Idesia polycarpa var.vestita Diels, enlarge planting area and contribute to increasing farmer income. The biodiesel is prepared by using the solid acid Zr(SO4)2.4H2O, so a series of troubles, such as equipment corrosion, potential safety hazard, environmental pollution and the like, caused by the traditional strong acid method are avoided, recovery rate is high, reaction time is short, and cost is reduce.

Description

technical field [0001] The invention relates to the technology of preparing biodiesel from vegetable oil, in particular to the preparation of biodiesel from tung oil through solid acid catalysis and its preparation method. technical background [0002] At present, the diesel oil used in large quantities is the diesel oil refined from petroleum, which is a non-renewable resource, and the amount of its resource is becoming more and more worrying. During the production, processing and use of this kind of diesel oil, there are hidden and direct threats to the ecological balance of the natural environment that cannot be underestimated, and it has become one of the prominent problems in the global warming greenhouse effect. Biodiesel has the characteristics of extremely low sulfur content, low aromatic hydrocarbon content, high oxygen content, and less exhaust gas escape. The development of biodiesel is beneficial to the protection of the ecological environment. The development ...
