Technical bottleneck for bio-based acrylates to replace petroleum-based products?

Technical bottleneck of bio-based acrylate replacing petroleum-based products

as the global focus on sustainable development continues to increase, bio-based materials have gradually become the focus of research to replace traditional petroleum-based products. As an important chemical, acrylate is widely used in coatings, adhesives, plastics and other industries. The development and promotion of bio-based acrylates still faces many technical bottlenecks, especially in the process of replacing petroleum-based products. This article will analyze these technical bottlenecks from the aspects of raw material acquisition, production process and cost competitiveness, and explore possible solutions.

1. The challenge of access to raw materials

the production of bio-based acrylates typically relies on renewable resources such as starch, cellulose, fatty acids, etc. The supply stability of these feedstocks is a key issue. Compared with petroleum-based products, bio-based feedstocks are more seasonal and volatile, making it difficult to stabilize production plans. The high cost of production of bio-based feedstocks also adds to the overall cost of bio-based acrylates.

Another problem is the conversion efficiency of the feedstock. At present, the production process of many bio-based acrylates requires multi-step chemical reactions, resulting in low utilization of raw materials. For example, in the production of acrylic acid by fermentation technology, both the conversion efficiency of microorganisms and the product separation efficiency need to be further improved. This not only increases the production cost, but also limits the market competitiveness of bio-based acrylates.

2. Technical limitations of the production process

compared with petroleum-based acrylate, bio-based acrylate production process is not yet fully mature. The production of petroleum-based acrylate mainly depends on the addition and polymerization of propylene, and the process is relatively simple and efficient. The production of bio-based acrylates usually requires complex biological fermentation or chemical synthesis processes, which may lead to longer production cycles and higher energy consumption.

Product isolation and purification processes for bio-based acrylates also present technical challenges. Due to the complexity of bio-based raw materials, the products often contain more impurities, and the separation and purification process requires additional energy consumption and cost. These process limitations further increase the difficulty of producing bio-based acrylates.

3. Cost and market competitiveness

despite the environmental and sustainable advantages of bio-based acrylates, their production costs are still higher than petroleum-based products. This is mainly due to the cost of raw materials and the immaturity of production technology. For example, the production of bio-based acrylates requires the use of special enzymes or catalysts, and the cost of these materials is high and the supply is unstable. The scale effect of bio-based production process has not been fully reflected, which makes it difficult to reduce the unit production cost.

The market awareness of bio-based acrylate is low, which limits its market demand. Many companies still prefer to choose petroleum-based products with lower prices and more stable performance. This difference in market perception further increases the difficulty of replacing petroleum-based products with bio-based acrylates.

4. Environmental and sustainability considerations

although bio-based acrylates are considered a more environmentally friendly option, there may still be some environmental issues during their production. For example, the cultivation and processing of bio-based feedstocks can place significant pressure on land, water and energy resources. The disposal of bio-based acrylates also requires more research to ensure that their impact on the environment is minimized.

5. Future development direction and solutions

faced with these technical bottlenecks, future research needs to focus on the following aspects:

• optimized raw material utilization: Improve the conversion efficiency of microorganisms through genetic engineering technology and develop more efficient raw material conversion processes.
• improve the production process: Study new catalysts and reaction conditions, simplify the production process and reduce energy consumption.
• Cost reduction: Reduce production costs and improve the market competitiveness of bio-based acrylates through large-scale production and technological improvements.
• Strengthen market promotion: Improve the market awareness of bio-based acrylates and promote their application in more fields.

Epilogue

the replacement of petroleum-based products by bio-based acrylate is an important direction to achieve sustainable development, but it still needs to overcome the technical bottlenecks of raw material acquisition, production process, cost competitiveness and so on. Through technological innovation and market promotion, it is expected to further break through these restrictions in the future, promote the wide application of bio-based materials, and contribute to the realization of the goal of green chemical industry.
