Catalytic pyrolysis of mixed plastic wastes using commercial grade kaolin and Ukpor clay from Nigeria
نویسندگان
چکیده
The aim of this study is to convert mixed plastic waste into usable liquid fuel via pyrolysis technique using Ukpor clay as a low-cost catalyst and commercial grade kaolin. Waste was catalytically degraded in laboratory scale semi-batch reactor at temperature 400 °C, residence time 45 min, heating rate 16 ˚C/min. catalysts were characterized by XRF analysis while proximate the feed carried out gave volatile materials content 95.17 wt%, fixed carbon 1.51 wt% ash 2.6 wt%. kaolin employed catalytic same feedstock for catalyst-to-plastic ratio 1:1, 1:2, 1:3, 1:4 operating parameters. Optimum yields obtained 1:3 both with yield 85.80, 3.58, 10.62 89.80, 6.33, 3.87 liquid, gaseous, solid products, respectively. products cracking optimum conditions their suitability fuel. properties determined density, viscosity, flash point, pour calorific value. results suggest that produced whose are comparable conventional fuels (gasoline diesel oil) process producing higher yield. GC-MS found most oil high aromatic some aliphatic other hydrocarbon compounds, FTIR product from also shows it contains hydrocarbons different functional groups such aromatics, olefins, carbonyl, amines, sulphides, hydroxyl.

Potential for energy recovery from municipal plastic wastes generated in Nigeria
Management of municipal solid wastes (MSW) in most developed societies now involves the use of thermo-chemical conversion methods. This leads to energy and material recovery while also protecting the environment. However, till date most of the wastes generated in Nigeria (including plastic wastes) are either land-filled or openly burnt. These methods are not sustainable and environmentally non-...

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...
Recycling Techniques of Polyolefins from Plastic Wastes
Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...

Synthesis of Bio-aromatics from Black Liquors Using Catalytic Pyrolysis
Bio-aromatics (benzene, toluene, xylenes, BTX) were prepared by the catalytic pyrolysis of six different black liquors using both in situ and ex situ approaches. A wide range of catalysts was screened and conditions were optimized in microscale reactors. Up to 7 wt % of BTX, based on the organic fraction of the black liquors, was obtained for both the in situ and ex situ pyrolysis (T = 500-600 ...
