摘要： A method of reducing wax deposition in an oil wellbore tubing includes providing an aqueous bioslurry comprising at least one microbe capable of degrading paraffin wax at about 20-45° C. and a nutrient medium containing one or more carbon source and an oxygen slow-releasing compound. The method further includes providing an oil wellbore completion having a production tubing with an interior surface including a zone that is susceptible to wax deposition when the well is operated to produce oil. The method further includes, while oil production from the well is stopped, incubating the biological slurry in the wax-deposition zone tubing for a sufficient time to multiply the microbe(s) and form a biofilm on at least the wax-susceptible zone.
摘要翻译：降低油井筒管中蜡沉积的方法包括提供含水生物乳液，其包含至少一种能够降解约20-45℃的石蜡的微生物和含有一种或多种碳源和缓释氧的营养培养基复合。该方法还包括提供一种具有生产管道的油井筒完井，其具有内表面，该内表面包括当井被操作以产生油时易于蜡沉积的区域。该方法还包括，当从井中产生石油停止时，将生物淤浆在蜡沉积区管中温育足够的时间以使微生物倍增，并在至少蜡敏感区上形成生物膜。

摘要： A method of reducing wax deposition in an oil wellbore tubing are disclosed which comprise providing an aqueous bioslurry comprising at least one microbe capable of degrading paraffin wax at about 20-45° C. and a nutrient medium containing one or more carbon source and a source of O2. The method further includes providing an oil wellbore completion having a production tubing with an interior surface including a zone that is susceptible to wax deposition when the well is operated to produce oil. The method further includes, while oil production from the well is stopped, incubating the biological slurry in the wax-deposition zone tubing for a sufficient time to multiply the microbe(s) and form a biofilm on at least the wax-susceptible zone

摘要： A method for processing lignocellulosic materials in which a lignocellulosic feedstock material is contacted with a mixture of dilute acid, metal salt catalyst and hydrogen peroxide and/or hydrogen peroxide-producing chemicals, resulting in the formation of an impregnated lignocellulosic material impregnated with at least one hydroxyl radical. The impregnated lignocellulosic material is then hydrolyzed.
摘要翻译：一种用于处理木质纤维素材料的方法，其中木质纤维素原料与稀酸，金属盐催化剂和过氧化氢和/或产生过氧化氢的化学品的混合物接触，导致形成浸渍了至少一种的木素纤维素材料羟基自由基。然后将浸渍的木质纤维素材料水解。
