Title:
PROCESSING SYSTEM AND METHOD FOR PREPARING ACETAL BY USING MONOHYDRIC ALCOHOL-AIR CATALYTIC CONVERSION
Document Type and Number:
WIPO Patent Application WO/2019/104810
Kind Code:
A1
Abstract:
Disclosed by the present invention are a processing system and method for preparing an acetal by using monohydric alcohol-air catalytic conversion, which solves the problems in the existing technology wherein costs are high, safety and environmental protection risks are high, conversion efficiency is low, fast and precise control of production conditions is not possible, and continuous industrial chemical production is not possible. The feeding system of the present invention comprises a raw material tank, a reciprocating metering pump, an air generating device, and a mass flow meter; a heating mixing system comprises a gas pre-heater, a liquid pre-heater, a gas pre-heating pipe, a liquid pre-heating pipe, a gas-liquid mixed pre-heating pipe, a vaporization mixer, and a overheating pipe; a catalytic conversion system comprises a fixed bed catalytic reactor; a condensing system comprises a deep cooler and a circulating refrigerator; a gas-liquid separation system comprises a gas-liquid separation tower, a product tank and a wet flow meter. A monohydric alcohol and air enter the heating mixing system by means of the feeding system and are heated and mixed, then entering the catalytic conversion system to react, a reaction tail gas being condensed by means of the condensing system and being separated by means of the gas-liquid separation system to obtain a liquid product containing the acetal.
