Abstract

An improvement in a process for the pyrolytic conversion of rubber and plastic waste to hydrocarbon products which results in reduced levels of nitrogen and sulfur impurities in these products. The improvement comprises pyrolyzing the waste in the presence of at least about 1 weight percent of salts, based on the weight of the waste, preferably chloride or carbonate salts, of zinc or copper (I). This invention was made under contract with or subcontract thereunder of the Department of Energy Contract #DE-AC02-78-ER10049.

Pyrolytic conversion of plastic and rubber waste to hydrocarbons with basic salt catalysts

Patent Wingfield, Jr., Robert C. ; Braslaw, Jacob ; Gealer, Roy L

The invention relates to a process for improving the pyrolytic conversion of waste selected from rubber and plastic to low molecular weight olefinic materials by employing basis salt catalysts in the waste mixture. The salts comprise alkali or alkaline earth compounds, particularly sodium carbonate, in an amount of greater than about 1 weight percent based on the waste feed.

Pyrolysis of tire rubber: Porosity and adsorption characteristics of the pyrolytic chars

Journal Article Miguel, G S ; Fowler, G D ; Sollars, C J - Industrial and Engineering Chemistry Research

Tire rubber has been pyrolyzed at various temperatures under a nitrogen atmosphere. The resulting chars have been analyzed for their porosity using nitrogen gas adsorption and for their aqueous adsorption characteristics using phenol, methylene blue, and the reactive dyes Procion Turquoise H-A and Procion Red H-E3B. Nitrogen adsorption isotherms were modeled to the BET and Dubinin-Astakhov (DA) equations to determine effective surface areas, mesopore volumes, and micropore volumes. Results showed that pyrolysis of tire rubber was essentially complete at 500 C and resulted in a char yield of approximately 42 wt%. Pyrolytic chars exhibited BET surface areas up to 85more »« less

Catalytic conversion of rubber wastes to produce aromatic hydrocarbons over USY zeolites: Effect of SiO ₂/Al ₂O ₃ mole ratio

Journal Article Wang, Jia ; Jiang, Jianchun ; Wang, Xiaobo ; ... - Energy Conversion and Management

Catalytic conversion of rubber wastes to produce an alternative fuel resource is a promising approach to dispose of solid wastes and address environmental issues. In this study, catalytic fast pyrolysis (CFP) of rubber wastes over acidic zeolites was conducted, and the effect of SiO ₂/Al ₂O ₃ mole ratio of USY zeolites on the formation of aromatic hydrocarbons was explored. Experimental results indicated that alkenes and aromatic hydrocarbons were the main pyrolytic products obtained from fast pyrolysis of rubber wastes, and the pyrolysis temperature played a vital role in the formation of aromatics with the highest concentration achieved at 750more »« less

Quality improvement of pyrolysis oil from waste rubber by adding sawdust

Journal Article Wang, Wen-liang ; Chang, Jian-min ; Cai, Li-ping ; ... - Waste Management

Highlights: • Rubber-pyrolysis oil is difficult to be fuel due to high proportion of PAHs. • The efficiency of pyrolysis was increased as the percentage of sawdust increased. • The adding of sawdust improved pyrolysis oil quality by reducing the PAHs content. • Adding sawdust reduced nitrogen/sulfur in oil and was easier to convert to diesel. - Abstract: This work was aimed at improving the pyrolysis oil quality of waste rubber by adding larch sawdust. Using a 1 kg/h stainless pyrolysis reactor, the contents of sawdust in rubber were gradually increased from 0%, 50%, 100% and 200% (wt%) during themore »« less
