Composite Catalysts in the Processing of Secondary Raw Materials for ABS Plastic Production
摘要
This study examines the potential for producing ABS plastic from secondary raw materials. The selection of secondary raw materials is based on their availability in Ukraine, which presents novel opportunities to develop alternative catalytic technologies for the production of ABS plastic precursors that are independent of oil prices. In order to achieve this objective, it is of particular importance to create selective and highly active catalysts. Currently, catalysts are understood to be composites comprising aluminosilicates, various carriers with an extensive range of modifiers, and the so-called PNNL catalysts. Accordingly, the aim of this study was to review existing catalytic technologies and promising catalysts for processing secondary raw materials (technical glycerol, bioethanol, and PS plastic waste) into monomers (acrylonitrile, butadiene, and styrene) for the subsequent synthesis of ABS plastic. The analysis of existing literature indicates that the production of acrylonitrile from glycerol represents a promising avenue for the advancement of environmentally sustainable organic synthesis technologies. Furthermore, the utilization of water-containing ethanol as a raw material for butadiene production offers a dual advantage in terms of financial and environmental considerations. The production of styrene from polystyrene using natural clinoptilolite presents significant advantages, offering an economically beneficial alternative for processing polymer waste into fuel-like products. It has been established that developing catalytic technologies for synthesizing ABS plastic precursors from secondary raw materials represents a promising direction, offering alternative, economical, and ecological technologies for their production.
