Rejected from Chemical Engineering Journal? The 6 Best Journals to Submit Next

CEJ's enormous submission volume forces rapid editorial triage. The editors are evaluating thousands of papers per month, and the standards have risen sharply as the journal's impact factor has climbed.

Volume-driven desk rejection

With 30,000+ annual submissions, CEJ desk-rejects a large fraction of papers, often within days. The editors don't have time for borderline cases. If your paper didn't immediately signal novelty in its title, abstract, and graphical abstract, it may not have received careful attention. This is a reality of high-volume journals, and it doesn't necessarily reflect the quality of your work.

The environmental science overlap problem

CEJ has expanded heavily into environmental applications: photocatalysis, adsorption, water treatment, membrane technology. This area now represents a huge fraction of submissions, and the competition is fierce. If your paper reports a new adsorbent for dye removal, a new photocatalyst for organic degradation, or a new membrane for water purification, you're competing against hundreds of similar papers. The editors are looking for something that stands out from this crowd, and incremental improvements to known materials or processes don't clear the bar.

Insufficient engineering relevance

Despite its broad scope, CEJ is still a chemical engineering journal. Papers that are purely chemistry (without engineering application or scalability considerations) or purely materials science (without process context) may be rejected for scope. The editors want to see engineering thinking: mass transfer, reaction kinetics, process design, scalability, or economic feasibility.

Novelty concerns

CEJ increasingly prioritizes papers that introduce new concepts, mechanisms, or approaches rather than papers that apply known methods to new substrates. If your paper uses an established technique on a new material without revealing new engineering principles, the editors may view it as routine.

1. Journal of Hazardous Materials

JHM is the closest alternative to CEJ for environmental engineering and remediation papers. The journal publishes research on hazardous materials detection, treatment, and management, including adsorption, advanced oxidation, electrochemistry, and nanomaterial-based remediation. Its impact factor (~12) is close to CEJ's, and the editorial team is experienced with the same types of submissions CEJ receives. If CEJ rejected your environmental paper on borderline grounds, JHM's editors may see more value in the environmental application angle.

Best for: Environmental remediation, pollutant removal, hazardous waste treatment, toxicology of engineered materials.

2. Water Research

For papers focused on water and wastewater treatment, Water Research is a premier journal with an impact factor around 11. It's more focused than CEJ, specifically covering drinking water treatment, wastewater processing, water reuse, and aquatic environmental science. If CEJ rejected your water treatment paper for being "too applied" or "too environmental," Water Research's scope may be a better match. The journal values thorough treatment studies with real water matrices and pilot-scale data.

Best for: Water treatment processes, wastewater engineering, membrane bioreactors, disinfection, and water quality monitoring.

3. Separation and Purification Technology

SPT covers all separation and purification methods: membrane separation, adsorption, extraction, distillation, chromatography, and crystallization. For CEJ papers that focused on separation science, SPT's specialized scope means reviewers who deeply understand your specific technique. The impact factor (~8) is lower than CEJ, but SPT is the top journal specifically for separation engineering. Papers that CEJ considered "too narrow" for its broad scope often thrive at SPT.

Best for: Membrane processes, adsorption studies, liquid-liquid extraction, gas separation, and purification methodology.

4. Chemical Engineering Science

CES is the oldest journal in chemical engineering and the most focused on engineering fundamentals. It publishes reaction engineering, transport phenomena, process systems engineering, and multiphase flow. If CEJ rejected your paper because it was "too fundamental" or lacked application data, CES values exactly that type of fundamental engineering science. The impact factor (~4) is lower, but CES carries strong historical prestige and reaches the core chemical engineering audience.

Best for: Reaction engineering fundamentals, transport phenomena, process modeling, multiphase systems.

5. Applied Catalysis B: Environmental

For photocatalysis, electrocatalysis, and environmental catalysis papers, Applied Catalysis B (IF ~22) is actually a step up from CEJ. The journal is extremely selective (~15% acceptance), but if your catalytic work is strong, the higher impact factor and specialized reviewer pool can work in your favor. Applied Catalysis B values mechanistic insight into catalytic processes, not just performance metrics. If your CEJ paper included strong mechanistic data, this journal may appreciate it more.

Best for: Photocatalysis, electrocatalysis, environmental catalysis, and catalytic reaction mechanisms.

6. Catalysis Today

For catalysis papers that need a more accessible home, Catalysis Today (IF ~6) publishes applied catalysis research across all areas. The journal often publishes special issues tied to conferences, and the acceptance rate (~35%) is more forgiving. If your CEJ paper was a solid catalysis study without a surprising result, Catalysis Today values thorough, well-executed work. The journal is particularly receptive to papers that connect catalyst characterization with performance data.

Best for: Applied catalysis, catalyst characterization, industrial catalysis, and conference-associated special issues.

Rejected for "not novel enough" in environmental remediation? Check whether the specific application (dye removal, heavy metal adsorption, pharmaceutical degradation) has a more targeted journal. JHM is the closest alternative, but journals like Chemosphere (IF ~8) and Environmental Science and Technology (IF ~11) may also fit.

Rejected for "insufficient engineering content"? If your paper is really a materials chemistry study, submit to a materials journal. If it's really an environmental science study, submit to an environmental journal. Don't try to force engineering framing onto non-engineering work.

Rejected for "incremental advance"? Add mechanistic insight, scalability data, or economic analysis. If you can't strengthen the novelty, Separation and Purification Technology, Chemical Engineering Science, or Catalysis Today will value thorough execution over novelty.

Desk rejected within days? Rewrite your abstract and graphical abstract to clearly communicate the novelty in the first two sentences. Then target a journal with lower submission volume where editors can give your paper more attention.

Strengthen your graphical abstract. High-volume journals like CEJ and JHM rely on graphical abstracts for quick screening. A clear, informative graphical abstract that communicates the main finding immediately can determine whether your paper gets a full read or a desk rejection.

Add engineering context. If your paper was rejected for being too fundamental or too chemistry-focused, add discussion of scalability, process integration, energy consumption, or techno-economic analysis. Even brief discussion of practical implications can shift a paper from "chemistry" to "engineering" in editors' eyes.

Include real-world relevance. For environmental papers, testing with real water matrices, actual industrial wastewater, or ambient air samples is increasingly expected. Synthetic solutions alone may not satisfy reviewers at any competitive environmental engineering journal.

Update your literature review. In fast-moving fields like photocatalysis and membrane technology, papers published 6 months ago are already part of the baseline. Make sure your literature review covers the most recent work and clearly positions your contribution relative to it.

High-volume journals move quickly, and a second rejection costs more time than a careful revision. Run your manuscript through a free Manusights scan to check scope alignment, formatting, and completeness before submitting to the next journal. A few hours of preparation can save weeks of waiting.
