造纸法再造烟叶加工技术分析 总被引:1,自引:0,他引:1
《广东化工》2021,48(14)
对于再造烟叶来讲,常常被人们称作烟草薄片,其包含着较多的原料,例如有烟梗、烟叶等。在烟叶中,通过加入适量的再造烟叶,能够带来很多的好处,具体而言,可以减少卷烟所需的成本、增强填充能力,减少焦油含量,更好地体现卷烟特征以及风格,更为关键的是,有助于提高吸食安全性等。与辊压法等进行对比,造纸法有着更为突出的优势,如成丝率高、密度相对小等,基于此,本文对造纸法再造烟叶加工技术进行了分析,以期能为相关人员提供借鉴。 相似文献

添加造纸法再造烟叶是卷烟降焦的重要手段,但再造烟叶烟气中CO含量相对较高,降低造纸法再造烟叶烟气中的CO含量刻不容缓。研究了Cu和Co等过渡金属氧化物催化剂在降低造纸法再造烟叶烟气中CO含量的催化性能。经过对催化剂的初步筛选,Cu-Mn复合氧化物催化剂表现出最佳的CO催化氧化性能。为进一步提高催化剂的利用效率及催化活性,从两个方面进行深入研究:(1)在再造烟叶制备过程中的不同工艺阶段加入催化剂,结果发现,将催化剂的固体粉末分散在浆料中,有助于得到催化剂分散均匀的再造烟叶,烟气中的去除率为12.8%;(2)将催化剂以不同的形式分散,结果发现,将催化剂前驱体溶液与涂布液混溶是使催化剂均匀分散的最好方式,利用此方式将Cu-Mn催化剂加入再造烟叶中,使CO去除率高达15%。表明过渡金属氧化物催化剂对降低再造烟叶烟气中CO含量表现出良好的催化性能,且催化剂在再造烟叶中的分散性对催化性能有着至关重要的作用。 相似文献

ABSTRACT Volatile flavors are playing an increasingly important role in the quality control of cigarettes to enhance their smoke taste and odor. The cigarettes which contain a filter tip having an activated carbon for reducing the irritant and physiological effects of the smoke are popular in the Japanese market. We found that the flavors migrate from the tobacco column to the filter tip, while spontaneously water moves backwards, depending on the adsorption equilibrium of cigarettes and its packaging.materials during storage. A new "Ethanol Adsorption Treatment" for a filter tip has been presented to decrease this undesirable flavor and water migrations. The treatment is performed by applying the binary vapor of water and ethanol to the filler tip before connecting ii with a tobacco column. Then during storage, the presence of ethanol vapor decreased the flavor migration mainly by decreasing the amounts of flavors adsorbed on the activated carbon within the filter lip. The treatment was confirmed to be effective for decreasing both flavor and water migrations simultaneously. 相似文献

为了开发新型烟用香料,将烟酸与各种香味醇合成3-吡啶甲酸酯添加到卷烟中,并对其卷烟加香效果进行评价。以3-吡啶甲酸和一系列具有香味的醇为原料,经酰氯化反应先制成3-吡啶甲酰氯,再与香味醇回流反应生成3-吡啶甲酸酯类衍生物。所有化合物结构均经1 H NMR、13^ C NMR、IR和HRMS得到确证。对目标产物进行卷烟加香评吸,评吸结果表明,与对照卷烟相比,加入各种3-吡啶甲酸酯类衍生物的卷烟香气质改善,香气量增加,达到烟香协调、余味净化、杂气减轻的效果。合成的新型吡啶酯类衍生物将有可能作为香原料应用到卷烟中。 相似文献

Regulations for cigarette ignition resistance (CIR) of soft furnishings (beds and upholstered furniture) and less fire‐prone cigarettes have contributed substantially to the decrease in losses from cigarette‐initiated fires over time. Two standard reference cigarettes play key roles in mitigating these losses and in sustaining the effectiveness of the fire safety regulations as exogenous changes occur. SRM 1082 provides a uniform, durable supply of cigarettes for use in ASTM E2187 that assures manufacturers and regulators of compliance with regulations for reduced ignition propensity cigarettes; enables quality control of cigarette fire test performance; enables assurance of uniform interlaboratory test results; obviates effects on fire safety as tobacco crops and smokers change over time; and, when the original ASTM E2187 substrate material was no longer available, enabled adding a new, equivalent substrate. SRM 1196 provides a uniform, durable supply of cigarettes for assurance of consistent interlaboratory evaluation of the ignition resistance of soft furnishings using the mandated test methods; obviates possible unknown changes in soft furnishings' CIR due to the evolving ignition strength of the original test cigarette over time; and provided a test cigarette that was stronger than most cigarettes being smoked after manufacture of the original commercial test cigarette ceased. 相似文献
