본 발명은 증가된 점도를 갖는 폴리아크릴아미드 용액을 제조하는 방법에 관한 것이다. 특히, 본 발명은 수성 아크릴아미드 용액의 폴리아크릴아미드로의 중합 전에, 생물촉매를 활용하여 제조된 수성 아크릴아미드 용액으로부터 생물촉매를 분리하는 것에 관한 것이다. 증가된 점도를 갖는 폴리아크릴아미드 용액은 3차 오일 회수에 사용하기에 매우 적합하다. 따라서, 본 출원은 3차 오일 회수에 사용하기 위한 폴리아크릴아미드 용액의 품질을 결정적으로 개선시키는 수단 및 방법을 제공한다. The present invention relates to a method for producing a polyacrylamide solution having increased viscosity. In particular, the present invention is related to the separation of a biocatalyst from an aqueous acrylamide solution prepared utilizing the biocatalyst prior to polymerization of the aqueous acrylamide solution to polyacrylamide. A polyacrylamide solution having increased viscosity is well suited to be used in tertiary oil recovery. Accordingly, the present application provides means and methods to crucially improve the quality of polyacrylamide solutions for use in tertiary oil recovery.
