Preparation method of Ageratina-adenophora-base high-specific-area activated carbon

The invention relates to a preparation method of Ageratina-adenophora-base high-specific-area activated carbon, belonging to the field of environmental protection. The method comprises the following steps: uniformly mixing KOH and an Ageratina adenophora carbonization material in a solid-phase state, filling into a ceramic crucible, and putting into a microwave high-temperature reactor; introducing nitrogen to evacuate air in the furnace, heating under microwaves to the last fewer minutes, quickly blowing CO2 into a guide tube communicated with the bottom of the ceramic crucible, and meanwhile, starting an ultrasonic generator; after finishing heating, washing the activated material with water, and recovering the residual KOH activator; and sequentially carrying out acid washing, water washing and drying to obtain the high-specific-area activated carbon. By using the Ageratina adenophora as the raw material, the method uses the CO2 bottom blowing mode to enhance the activation effect of the carbonization material, thereby lowering the production cost of the activated carbon, relieving the environmental pollution, changing harmful substances and waste into valuable substances and implementing comprehensive utilization of natural resources. The high-specific-area activated carbon can be effectively used in the fields of adsorptive collection of gasoline and other organic substances in automobile exhaust emissions and fuel system volatile substances, solvent recovery and the like.

Method and device for high temperature sterilization by using steam explosion

InactiveCN103721274AShorten the sterilization cycleShorten the high temperature maintenance timeHeatNutrientProcess engineering
The invention provides a method and device for high temperature sterilization by using steam explosion, which are short in sterilization cycle, low in destruction rate of nutrient substances, loose in materials, easy to amplify, and high in production efficiency aiming at the defects that conventional high-pressure steam sterilization is long in cycle, serious in damage to nutrient substances, easy in caking and the like. According to the method and device provided by the invention, the sterilization time is shortened by improving the sterilization temperature, so as to possibly reduce the damage to the nutrient substances. Meanwhile, the materials and the steam are ejected in a burst state in a rapid emptying manner, so as to loosen a culture medium and simultaneously shorten the cooling time. Thus, the overall sterilization cycle is shortened. The method and the device can facilitate industrial production of solid state fermentation by improving the production efficiency and the fermentation effect of the culture medium.
