The present invention discloses catalyzed hydrogen reduction process of alkyl halide to dehaloginate and produce hydrocarbon. The process adopts alkyl halide as main material, inorganic palladium salt microcapsule as catalyst in the amount of 0.01-2 %, methanol and ethanol, n-hexane or tetrahydrofuran as solvent, and has hydrogen as reductant in 0.1-2.0 MPa introduced to react at 20-120 deg.c for 1-10 hr. The present invention has reuse of inorganic palladium salt microcapsule as catalyst, and possesses the advantages of no pollution, mild condition, high operation safety, easy separation of the catalyst for reuse, etc.
