Chemical Engineering Journal Impact Factor 2026: Ranking, Quartile & What It Means

Chemical Engineering Journal (CEJ) has an impact factor of 13.2 according to the 2024 Journal Citation Reports — the latest official figure available in 2026. The 5-year impact factor is 13.5, indicating stable and slightly rising performance.

What the number means

Ranking 3rd out of 83 chemical engineering journals puts CEJ in the top 4% of the field. An IF of 13.2 means the average paper published in CEJ in 2022-2023 was cited roughly 13 times by the end of 2024. For an engineering journal — where citation rates are typically lower than in basic sciences — this is an exceptionally strong figure.

CEJ's rise in IF over the past decade reflects the growth in materials-related chemical engineering work, particularly environmental remediation, energy storage, and catalysis. These areas generate high citation volumes because they are interdisciplinary and attract readers from materials science, environmental science, and applied chemistry, not just chemical engineering proper.

Benchmark against peers

CEJ sits in an interesting middle tier — well above traditional chemical engineering journals like Chemical Engineering Science and AIChE Journal, but below the elite energy/materials journals. For authors doing applied materials or process engineering work, CEJ is often the right practical target.

Why the 5-year IF matters here

The 5-year IF of 13.5 is slightly higher than the 2-year IF of 13.2. This means papers in CEJ are accumulating citations consistently over time rather than getting a burst of early citations that fades. For researchers in environmental engineering and materials-heavy areas, this long-term citation pattern reflects broad utility of CEJ papers as references in subsequent work.

What the IF doesn't capture

Journal scope has broadened. CEJ now publishes extensively in environmental applications, photocatalysis, electrochemistry, and materials for energy. Authors from adjacent fields target it heavily. If your work is primarily a materials science paper without strong engineering framing, reviewers may flag scope.

Acceptance has become more competitive. CEJ's growth in IF has attracted more submissions. The journal's acceptance rate has tightened; papers that would have cleared review five years ago may face tougher scrutiny now. Strong characterization, clear engineering application, and practical context are expected, not optional.

Not all subfields benefit equally. The IF is an average. Papers in high-activity areas like photocatalytic water splitting or CO2 reduction get cited heavily; papers in niche process engineering topics may cite fewer times but reach a more targeted audience.

Who should submit to CEJ

Submit to CEJ if:

• Your work addresses a chemical or environmental engineering problem with clear practical relevance
• The study involves materials synthesis or process design with engineering characterization (not just physical property measurement)
• Results have application potential in energy, environment, separation, or reaction engineering
• You have solid data with mechanistic insight, not just performance reporting

Consider alternatives if:

• Work is primarily fundamental chemistry without engineering application (JACS or Angewandte Chemie may be better)
• The engineering is primarily mechanical or civil (separate journal families)
• The work is incremental within a specialized niche; a lower-IF specialist journal may give better community visibility

CEJ editors are attentive to engineering framing and practical context. If you want a read on whether your manuscript meets CEJ's current bar, Manusights pre-submission review checks scope fit and framing before you submit.
