New way to break Carbon Dioxide into useful chemicals

A novel catalyst breaks carbon dioxide into useful chemicals faster, cheaper, and more efficiently than the standard method, an advance that could make it possible to economically turn CO2 into fuels, scientists say. The extra carbon dioxide in the atmosphere is changing the planet’s climate, and many chemists are working on efficient ways to turn it into other useful products. However, the researchers noted that carbon dioxide’s stability makes this tough. It’s hard to get the molecule to react with anything else. The best existing technique to electrochemically break carbon dioxide into pieces that will chemically react uses a catalyst made of platinum, which is a rare, expensive metal, they said. In the research the scientists created an electrochemical cell filled with a porous, foamy catalyst made of nickel and iron, metals which are cheap and abundant.

The supply-chain inflation threat to petrochemicals demand

Article | June 6, 2022

Petrochemicals themselves remain in short supply. This is partly because of reduced feedstock from refineries, a consequence of the pandemic-related collapse in transportation fuels demand.Global petrochemical supply is still edging back to something like normal following the US winter storms in February, during which most US capacity was shut down. A point of discussion is whether containers will become available in the right places at the right prices to relieve tightness in the European polyethylene (PE) market, once US supply has normalised. The container issue is making it difficult to move PE and polypropylene (PP) cargoes from Asia to Europe.Market intelligence from the US-based ICIS CDI team indicates that enough container freight space will be available to resume significant shipments of US PE to Europe, albeit at high prices. It will be several more weeks before domestic pipelines have been refilled, enabling US producers to refocus on exports, added CDI.

Key Trends in the Digital Transformation of the Chemical Industry

Article | August 2, 2022

The chemical business is intricate, with numerous sub-sectors dealing with various challenges. Thus, there are some differences in the sector's main areas of digitalization. For instance, while specialty chemicals with smaller batches but larger profit margins are concerned with improving quality, large factories are concentrated on accelerating throughput speed. To be able to react to quick and repeated changes in demand, supply, and working circumstances, however, every plant must optimize output, reduce waste, improve safety and sustainability, and become more nimble. Therefore, the Industrial Internet of Things (IIoT), artificial intelligence (AI), and cloud computing are expected to be the three most popular applications for digital transformation during the coming two years. Key Trends Production Optimization The first and most valuable use cases of digitalization in chemical plants center on production optimization through improved equipment performance, process automation, remote and predictive monitoring, and simplified maintenance. Chemical factories, which often provide basic chemicals for use as end products in other sectors, have a special responsibility to maintain consistently high product quality. However, doing so can be challenging given the significant variations in raw material supply and quality. In addition, as process engineers can change the mix on the fly in reaction to fluctuations in quality, feedstock, or ambient temperatures, better data and analytics enable finer and more frequent adjustments. Lowering Waste The main advantage of digitally transformed plants so far has been cost reduction. The price volatility of raw materials is a problem for the chemical production sector because customers naturally want constant low prices. Minimizing waste is critical since facilities must contend with rising energy costs. Analytics tools that monitor fluctuating raw material prices aid factories in negotiating the best deals with suppliers and preparing in advance for price spikes. The risk of oversupply is reduced since plants can prepare the proper quantities of various products thanks to more precise demand predictions. Sustainability, Compliance, and Safety The chemical industry is heavily regulated as a result of the quantity of hazardous chemicals and the number of end-use industries that rely on it. Businesses are adopting digital transformation to boost safety awareness, reduce emissions and dangerous flare incidents, and guarantee a transparent and accurate audit trail. Plants that quickly adopt digital solutions for remote monitoring, supply chain visibility, waste reduction, production optimization, raising their safety profile, and opening up new opportunities will profit from higher profits and increased revenue, whereas those that hesitate for too long risk failing in the long run.

Organic Catalyst Boasts Big Benefits

Article | June 6, 2022

An enzyme-mimicking catalyst opens a new route to important organic molecules such as glycolic acid and amino acids from pyruvate, report researchers in Japan. Moreover, the new catalyst is cheaper, more stable, safer and more environmentally friendly than conventional metal catalysts used in industry, they note, adding that it also displays the high enantioselectivity required by the pharmaceutical industry. “On top of these advantages, our newly developed organic catalyst system also promotes reactions using pyruvate that aren’t easily achievable using metal catalysts,” says Santanu Mondal, a PhD candidate in the chemistry and chemical bioengineering unit at Okinawa Institute of Science and Technology (OIST) Graduate University, Okinawa, Japan, and lead author of a study recently published in Organic Letters. “Organic catalysts, in particular, are set to revolutionize the industry and make chemistry more sustainable,” he stresses. The researchers use an acid and an amine mixture to force the pyruvate to act as an electron donor rather than its usual role as an electron receiver (Figure 1). Effectively mimicking how enzymes work, the amine binds to the pyruvate to make an intermediate molecule. The organic acid then covers up part of the intermediate molecule while leaving another part that can donate electrons free to react to form a new product. Currently, the organic catalyst system only works when reacting pyruvate with a specific class of organic molecule called cyclic imines. So, the researchers now are looking to develop a more-universal catalyst, i.e., one that can speed up reactions between pyruvate and a broad range of organic molecules. The challenge here is to try to make the electron-donating intermediate stage of pyruvate react with other functional groups such as aldehydes and ketones. However, different catalysts create different intermediates, all with different properties. For example, the enamine intermediate created by the researchers’ new reaction only reacts with cyclic imines. Their hypothesis, currently being investigated, is that creation of other intermediates such as an enolate, if possible, would achieve a broader pyruvate reactivity. In terms of cost, the researchers note that a palladium catalyst used in similar reactions is 25 times more expensive than their organic acid — which also is made from eco-friendly quinine. In addition, they believe scale-up of the process for industrial use definitely is possible. However, the researchers caution that the current amine-to-acid-catalyst loading ratio of 1:2 probably would need to be optimized for better results at a larger scale.

NGOs file suit over transparency of TSCA new chemicals programme

Chemical Watch | March 18, 2020

A coalition of NGOs has sued the US EPA over an alleged lack of transparency in the TSCA new chemicals programme, which "thwart[s] the ability of the public to be informed and to provide input". According to a complaint filed by five environmental nonprofits in federal court today, the EPA has operated its TSCA premanufacture review process in a "black box, denying the public information to which they are legally entitled". Having access to timely information, they contend, is necessary to ensure the members they represent "are able to provide input on the potential risks of new chemicals and the need for protections from those risks prior to completion of EPA’s reviews." And they therefore have asked the court to ensure that the EPA complies with TSCA’s disclosure provisions, including by requiring that it:
