Context. Primordial black holes (PBHs) have been proposed as potential candidates for dark matter (DM) and have garnered significant attention in recent years. Aims. Our objective is to delve into the distinct impact of PBHs on the gas properties and their potential role in shaping the cosmic structure. Specifically, we aim to analyze the evolving gas properties while considering the presence of accreting PBHs with varying monochromatic masses and in different quantities. By studying the feedback effects produced by this accretion, our final goal is to assess the plausibility of PBHs as candidates for DM. Methods. We developed a semianalytical model that works on top of the CIELO hydrodynamical simulation around z similar to 23. This model enables a comprehensive analysis of the evolution of gas properties affected by PBHs. Our focus lies on the temperature and hydrogen abundances, with specific emphasis on the region closest to the halo center. We explore PBH masses of 1, 33, and 100 M-circle dot, located within mass windows in which a substantial fraction of DM could exist in the form of PBHs. We investigated various DM fractions composed of these PBHs (f(PBH )> 10(-4)). Results. Our findings suggest that PBHs with masses of 1 M-circle dot and fractions greater than or equal to approximately 10(-2) would be ruled out due to the significant changes induced in the gas properties. The same applies to PBHs with a mass of 33 M-circle dot and 100 M-circle dot and fractions greater than approximately 10(-3). These effects are particularly pronounced in the region nearest to the halo center, potentially leading to delayed galaxy formation within halos.
