Abstract

The invention discloses a deactivation-resisting automobile three-way catalytic converter carbon deposit biological cleaning liquid comprising the following components: 5-15% of a petroleum hydrocarbon degrading bacterium extract, 0.5-1% of a buffering agent, 5-10% of a fatty acid salt surfactant, 1-5% of alcohol, 5-10% of an enzyme activity protecting agent, and 64-78.5% of deionized water. The enzyme activity protecting agent is one or more selected from bovine serum albumin, trehalose and beta-cyclodextrin. The petroleum hydrocarbon degrading bacterium extract comprises enzyme and a biological surfactant. The deactivation-resisting automobile three-way catalytic converter carbon deposit biological cleaning liquid provided by the invention is not prone to deactivation, and is environment-friendly and safe. The cleaning liquid is suitable to be used in cleaning automobile three-way catalytic converters.

Description

technical field [0001] The invention relates to a biological cleaning liquid for carbon deposits in a three-way catalytic converter of an automobile which is not easily deactivated, and belongs to the field of biological environmental protection. Background technique [0002] Three-way catalytic converter poisoning failure and clogging are the most common problems in environmentally friendly engines. Each system of the environmental protection engine works around the center of maximizing the conversion efficiency of the three-way catalytic converter. Once the three-way catalytic converter is poisoned, fails and is blocked, the conversion efficiency cannot be guaranteed, and the environmental protection engine cannot work normally. Therefore, the three-way catalytic converter Maintenance issues are at the center of environmental engine maintenance. [0003] Carbon deposits are a kind of sticky substance produced by unsaturated olefins and gums in fuel at high temperature dur...
