The invention relates to a fatty alcohol-polyoxyethylene ether sulfate with high content and a production technology thereof, and aims at providing a surfactant which is small in moisture content, good in mobility, convenient to transport, low in cost and convenient to use. The provided technology has the characteristics of simple process, and low energy consumption. The technical scheme is that the fatty alcohol-polyoxyethylene ether sulfate surfactant with high content comprises the following components by corresponding weight percent: 75-90% of fatty alcohol-polyoxyethylene ether sulfate, 0-9% of inorganic salt and the balance being water. The production technology of the fatty alcohol-polyoxyethylene ether sulfate surfactant is carried out according to the following steps orderly: (1) carrying out sulfonation on fatty alcohol-polyoxyethylene ether and SO3, so as to prepare fatty alcohol-polyoxyethylene ether sulphate; (2) feeding polyoxyethylene ether sulphate, alkali, water, inorganic acid or inorganic salt to a vacuum neutralization system according to the ratio, controlling the pH above 6.5 after neutralization; and (3) feeding the neutralized material to a tank zone to store through a delivery pump.
