چکیده

Bioemulsifiers are a unique class of compounds that have been shown to have a variety of potential applications in the use of bacteria, in enhanced oil recovery and reduce oil viscosity. In this project, a bioemulsifier was synthesized by strain of Bacillus licheniformis and was separated by autoclave and centrifugal process; the purification of bioemulsifier and the increase quality of product was done by add sulfuric acid (H2SO4) (98%) to solution and centrifuged again. This bioemulsifier has the property of emulsification a wide range of heavy oils to form a stable oil-water emulsion. This bioemulsifier could reduce heavy oil viscosity of about 10000 cp to 250 cp for O/W emulsion. It is about 97% decreasing in heavy oil viscosity. the viscosity decrease measurements abide for a period of up to about 8 days.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
